A Brief History of a “Silent” Tissue

Cartilage was first observed in detail by the “father of histology,” Marie François Xavier Bichat, in the late 1700s. At the time, early anatomists thought cartilage was simply a form of “soft bone” or a primitive precursor to the skeleton.

Later discoveries revealed it to be far more sophisticated. In the 19th century, researchers realized that unlike almost every other tissue in the body, mature articular cartilage has no blood vessels, no nerves, and no lymphatic system. It is an island unto itself, surviving in a high-pressure environment that would crush other tissues.

The Litany of Aging

Cartilage may be the single most important structure shaping not just how you age, but how you feel right now and what you are capable of as the decades pass. Consider the standard “litany” of age-related complaints:

• Stiffness

• Achiness

• Occasional sharp pains

• Tightness

• Pinching

These sensations can be many times be traced to the health of your cartilage, its thickness, what’s happening underneath it and how it responds to the internal environment of your joints. I recently watched a patient in the early phases of rehab tentatively demonstrating a step-down from a six-inch box. It is a movement that should be effortless, yet they were hesitant and wincing. Although they were weak, that wasn’t why they hurt. I see this play out repeatedly in patients, friends and family: the “hitch” in the get-up, the groan when sitting.

What is at the root of this mysterious structure, and what is the gold standard of self-care to preserve it? By the end of this post you’re going to have not just the knowledge, but a set of free tools to help you optimize your own joint protection plan.

Anatomy: The Living Hydrogel

To understand why things feel like they are “going downhill” as we age, we have to look at how cartilage is formed. Every physical structure in your body is constantly being remade; you are a work in progress.

In the world of biology, we use the suffix -blast for the builders and -clast for the recyclers. These terms apply to most musculoskeletal structures, but cartilage plays by different rules.

• Bones have osteoblasts (builders) and osteoclasts (recyclers).

• Tendons have tenoblasts.

• Cartilage? Cartilage has chondrocytes.

Here is the catch: while your bone cells are hyper-active and well-supplied by blood, and your tenocytes are triggered by specific loading strategies, chondrocytes are sparse and tucked away in a dense matrix. As we age, these cells don’t necessarily die off en masse, but their “metabolic machinery” slows down. This shift is guided by cellular senescence (where cells stop dividing but don’t die) and the shortening of telomeres, which act as the biological clocks of the cell.

Research suggests that we hit “inflection points”—notable shifts in our metabolic profile—around ages 44 and 60. During these windows, the gap between “tissue breakdown” and “tissue repair” can widen. This is why cartilage is unique: it has a very limited “repair budget” compared to muscle, tendon, or bone.

Think of cartilage not as “gristle,” but as a high-tech biological hydrogel. It is a microscopic mesh of collagen fibers packed with proteoglycans—molecules that act like powerful magnets for water. This creates a permanent state of internal swelling pressure. When you step down, you aren’t landing on a solid; you are landing on a pressurized cushion of trapped water that refuses to be displaced. It is the only material on Earth that can stay this slick and this durable for eighty years without a single drop of direct blood flow.

The Movement Diet

The good news is that the key to unlocking cartilage health is staring you in the face. Cartilage functions like a pressurized sponge. Because it has no blood supply, it relies on diffusion to stay alive.

Cartilage is a matrix of collagen, proteoglycans, and water. A healthy “movement diet” provides the mechanical pressure needed to squeeze this matrix. When you compress a joint, you push out metabolic waste; when you release the pressure, the cartilage sucks in fresh synovial fluid. This fluid is the “joint milk” that carries oxygen and nutrients to the chondrocytes.

Too little motion and the fluid becomes stagnant. The cartilage literally starves.

What is Arthritis, Really?

We can replace joints and repair tendons, but we cannot yet truly “regrow” original articular cartilage. This is where the “A-word” comes in.

In a typical joint, our chondrocytes number in the millions (roughly 7,000 to 10,000 cells per cubic millimeter). Over a lifetime, some of these cells are damaged. Like water eroding soil, these damaged areas leave tiny gaps like little potholes. Eventually, the erosion can reach the “subchondral bone” beneath.

Bone is incredibly strong, but it cannot handle the friction of motion. When bone rubs on bone, it becomes inflamed and painful. Is it always painful? No. Many people have “bone-on-bone” changes on an X-ray but feel zero pain. Why? Because cartilage loss is a mechanical state, not a sensory one. The pain only arrives when the underlying bone or the surrounding joint capsule becomes irritated.

The Repair Gap: Why Cartilage Is the Ultimate “Legacy” Tissue

We can set a broken bone and it knits back together stronger than before. We can suture a torn muscle and it heals with scar tissue. But cartilage? Cartilage is the one structure we can’t simply “fix.”

Because it lacks a blood supply, it lacks the raw materials for a traditional healing response. When you cut your skin, blood brings in the “cleanup crew” and the “construction crew.” In the white, silent world of cartilage, there is no road system for these crews to travel. If a chondrocyte dies or the collagen matrix is torn, the body essentially leaves the “pothole” as it is.

The Cortisone Conundrum

For decades, the medical “fix” for the resulting bone irritation has been cortisone. It is a powerful anti-inflammatory steroid that acts like a fire extinguisher. It doesn’t repair the cartilage; it simply numbs the “smoke alarm” of the underlying bone and the joint lining (synovium). While it provides temporary relief, we now know through research that repeated cortisone injections can actually accelerate cartilage breakdown by inhibiting the already slow metabolic activity of those chondrocytes. It is a short-term gain for a long-term cost.

The Rise of Regeneratives

This gap is where regenerative medicine—like Platelet-Rich Plasma (PRP) or Bone Marrow Aspirate—has entered the picture. These aren’t “magic erasers” that regrow a 20-year-old’s joint. Instead, they act like a high-octane fertilizer. By injecting concentrated growth factors directly into the joint environment, we aim to “wake up” the sluggish chondrocytes, reduce the toxic inflammatory soup, and potentially stabilize the existing matrix. It’s about optimizing the biology you have left, rather than replacing it.

The Modern Bionic Joint

When the “potholes” finally become “craters” and the bone can no longer handle the friction, we turn to joint replacement. The good news? We are living in the golden age of orthopedic engineering.

The latest generation of joint replacements has solved the “longevity” problem that plagued earlier models. We have replaced natural cartilage with Highly Cross-Linked Polyethylene (HXLPE)—an ultra-high-molecular-weight plastic that is chemically “cooked” to create incredibly strong bonds. This material is so durable and wear-resistant that the “shelf life” of a modern hip or knee has jumped from 10–15 years to 25 years or more. We are effectively replacing your living hydrogel with a “forever” plastic lining that can handle the mileage of an active life.

Before you make that call to get a new joint or to spend potentially thousands of dollars on regenerative therapies, make sure you’ve tried what’s been the gold standard for cartilage health and joint comfort - movement and exercise.

The Evidence for Action

We used to tell people with “wear and tear” to rest. We now know that was the worst possible advice.

• GLA:D Program: This landmark “Good Life with Osteoarthritis in Denmark” program proved that supervised neuromuscular exercise reduces pain and increases physical activity in people with knee and hip osteoarthritis (Source).

• The 2013 “Running” Study: Research published in Medicine & Science in Sports & Exercise found that runners actually had a lower risk of osteoarthritis compared to walkers, likely because the dynamic loading strengthened the cartilage matrix. Here’s a more recent review article and meta-analysis with additional info.

• The LIFTMOR Trial: This study showed that high-intensity resistance training in older women with low bone mass was not only safe but improved functional performance. Even with existing cartilage thinning, the “system” (muscles and bones) became more resilient (Source).

The Cartilage Playbook

How do we keep it healthy as long as possible?

1. Don’t be afraid of motion.

Motion is the only way to “feed” your joints. If a joint is sore, you don’t stop; you adjust the dosage.

2. Frequency over Intensity.

Synovial fluid is “thixotropic”—it thins when you move and gels when you sit. If you sit for hours, it thickens, leading to that “ugh” stiffness. Aim for a movement snack every 30 to 45 minutes. Even a 60-second walk to the kitchen “restarts” the clock.

3. The “Chill or Kill” Rhythm.

Do you need to move constantly? No. Research into “cyclic loading” suggests that cartilage cells respond best to short bouts of loading followed by rest. After about 10 to 15 minutes of continuous loading, the “pro-growth” signals in cartilage peak and then plateau. Pushing for three hours straight doesn’t necessarily help your cartilage more than 20 minutes of smart loading.

4. Watch for “Form Fatigue.”

Your muscles will fatigue before your cartilage does. When your knees start to cave or your pelvis collapses on a bike, your cartilage takes the “unaligned” brunt of the force. When your form breaks, your session is done.

If You Are in Pain: PEACE and LOVE

If your joint is already irritated, the bone beneath is likely the culprit.

• Micro-dose: Instead of a three-mile walk, do six half-mile walks.

• PEACE and LOVE: This is the modern replacement for RICE (Rest, Ice, Compression, Elevation). It stands for Protection, Elevation, Avoid anti-inflammatories (initially), Compression, Education... and Load, Optimism, Vascularization, and Exercise.

Can You Get Ahead of It?

Is cartilage loss genetic? Partly. Studies suggest heritability for osteoarthritis ranges from 40% to 60%. However, you are not your DNA. You can absolutely get ahead of the pain even if the structure isn’t optimal. By building the “muscular armor” around your joints and keeping your “movement diet” consistent, you can have a high-functioning, athletic life even with a “changing cartilage landscape.”

Now Let’s Move

To make this routine effective, we have to respect the biological rhythm of your chondrocytes. Research into cyclic loading suggests that cartilage responds best to short, frequent bouts of compression rather than one massive marathon of movement.

Think of these as “rehydration breaks” for your joints. Here is a high-value, low-friction Cartilage Movement Snack routine you can integrate into a standard workday.

The “Joint Milk” Daily Schedule

Goal: Move every 45–60 minutes to prevent synovial fluid from “gelling.”

How to Get the Most Out of This Routine

Remember, this isn’t about sets, reps, or burning calories. The goal is simple: rehydrate your cartilage matrix.

• The Squeeze-and-Release: Think of your cartilage like a hardened sponge. When you perform the slow bodyweight squat or the incline push-up, you are using muscle tension to compress that matrix. This squeezes out metabolic waste.

• The Inflow: As you stand up or release the push-up, you create a “vacuum” effect that draws in fresh synovial fluid (the “joint milk”). This delivers the oxygen and nutrients that your cartilage cells desperately need.

• Low-Load, High-Frequency: We aren’t trying to build massive muscle here; we are trying to maintain the chondrocyte phenotype (keeping the cells in “builder mode”). By keeping the intensity low, we avoid bone-on-bone irritation while maximizing the metabolic benefit to the cartilage.

• Combatting “Thixotropy”: As mentioned in the post, synovial fluid is thixotropic. It gets thicker and more viscous the longer you stay still. These snacks keep the fluid at a “water-like” consistency, which reduces the friction coefficient within the joint.

• Consistency Wins: Your cartilage doesn’t have a storage tank for these nutrients; it needs a steady “meal” throughout the day. Set a timer. Post this image on your desktop. Build the habit of moving, just a little bit, every hour.

Pro-Tips for the Playbook

• The 5-Minute Rule: If a specific movement causes a sharp pain that lasts longer than 5 minutes after you stop, reduce the range of motion (e.g., don’t squat as deep).

• Use a Timer: Don’t rely on your memory. Use an app like Focus To-Do or Stand Up! to nudge you every hour.

• Consistency > Intensity: Doing 10 squats every hour is significantly better for cartilage longevity than doing 100 squats once a week.

To your good health!

Burke

I’m in Pichilemu, Chile, for a few days of R&R after an intense window of racing at the Pan American continental championships. Pichilemu is a place where a world-class surfing destination and a traditional fishing village have amiably decided to coexist. There’s just enough specialty coffee to keep the surfers caffeinated and more than enough jumbo-sized, sandy churro carts to keep the tourists happy.

Punta de Lobos and La Puntilla deliver some of the most beautiful disciplined lines of swell on earth while five minutes away the sidewalks dissolve into gravel and dogs sleep diagonally across traffic lanes with complete authority. Nothing is optimized, everything is functional, just barely, and I love it.

As I watch the Pacific swells, I’ve been reflecting on my contract therapist role with the USA Track Cycling team. Behind every podium finish is a small army of coaches, therapists, mechanics, and analysts. We are the Biological Gyroscopes of the team. If we do our jobs well—tuning the bikes to the millimeter, timing the intervals, managing the recovery—we are hardly noticed. We provide the silent, self-correcting stability that allows the athlete to execute at 70kph without the wheels coming off.

This is exactly how your body’s most underappreciated structure works: The Rotator Cuff.

The Invisible Tripwire

After months of low-grade chronic soreness, Mike decided to jump back into the lap lane. He dove in, expecting the familiar glide of his freestyle stroke. Instead, the water felt like wet concrete. By the time he reached for a coffee mug the next morning, the sharp, biting pain in his shoulder made even that simple task feel like a feat of will.

Meanwhile, a high-power road ride for another athlete was catastrophically interrupted by a fall and a shoulder fracture. The surgery was a success—pins in place, bones compressed. But as the bones knit back together, a new problem emerged: the muscles had atrophied. The “hardware” was fixed, but the “software” had gone offline.

Whether it’s a slow fade in the pool or a sudden snap on the pavement, the crisis is rarely just the tissue; it’s the signals driving it. Your rotator cuff is the only thing standing between a functional limb and a catastrophic dislocation every time you reach for a glass of water.

An Anatomy Lesson in Awe

For millennia, it wasn’t like this. As our ancient ancestors transitioned from quadrupedal walking to upright reaching, our shoulders became the most mobile and most vulnerable joints in the kingdom.

Hold your arm out in front of you. Just hold it there. You are executing a balletic masterpiece of coordination, supporting the cantilevered weight of your entire limb through a joint roughly the size of a golf ball.

The Startling Reality: Your entire shoulder complex is attached to your skeleton by just one single bone-to-bone bridge: the clavicle (collarbone). Every other connection? Your shoulder blade isn’t bolted to your ribs; it “floats” on a bed of muscle. Your shoulder is less like a door hinge and more like a suspension bridge, held aloft by high-tension cables.

The joint itself is a lesson in elegance. Imagine a postage stamp (the glenoid) with two big scoops of vanilla ice cream (the humeral head) balanced on top. Instead of a sturdy waffle cone, you’re using a flat sugar cookie. Now, add the weight: the average adult female arm is about 8.5 lbs—roughly a gallon of milk. When you hold that arm at 90 degrees, physics multiplies that weight into 40–50 pounds of force pulling on four tiny muscles no thicker than duct tape.

The Ghost in the Machine

How does that scoop stay on the cookie? It’s held by the Invisible Choreographers: the four muscles of your rotator cuff.

Most people think of muscles like light switches: flip it, and the arm moves. But the cuff is a high-end smart gyroscope. It “pre-fires” milliseconds before you even touch a door handle, constantly adjusting the tension to keep the joint centered no matter where you move your arm and with whatever additional weight.

In my work with USA Cycling, the staff operates exactly like this. We aren’t the ones pushing the pedals (the “Big Movers”), but we are the Autopilot. We sense the “temperature” of the team, the fatigue, the mechanical drag, the wind resistance, and make micro-adjustments before the athlete even realizes there’s a problem.

The Silent Sabotage

When the software glitches, the car doesn’t stop, it just recruits a different driver.

When your cuff slacks off, the brain recruits the “Big Movers” (upper traps, deltoids, lats) to stabilize the joint. But these muscles are “Big and Dumb”; they lack the precision of the gyroscope to keep the golf ball centered on the postage stamp. They have other jobs to do, and those jobs suffer when they are forced to play bodyguard.

You don’t feel this immediately. You just feel “tight neck” or “heavy shoulders.” It’s like a hand on a steering wheel constantly pulling your car toward the curb. Just as a cycling team becomes vulnerable if the staff stops communicating, your shoulder performance crumbles when the gyroscope goes on strike.

The Good News: Rehab is a Software Update

If you have shoulder aches or a diagnosed tear, don’t panic. We need to leave the reductionist thinking that a tear is a “broken bike spoke” that must be replaced and truly understand the power of motor control, activation and programming.

• The MRI Paradox: 34% of people with zero pain have tears. Over age 60, it’s 54%. Tears are often just “wrinkles on the inside.”

• The Goal: As a 2016 review noted, the goal isn’t necessarily to “heal” the tendon, but to optimize the function of the remaining crew.

Actionable Intel: Reclaiming the Joint

If a gyroscope isn’t working, you don’t make it bigger, you calibrate it. Try these four movements to assess your “software.”

1. The “Snow Angel” (Alignment)

Lie on your back, knees bent. Slide your arms away from your body like you’re making a snow angel, keeping hands and elbows on the floor.

• The Glitch: If your arm lifts or your ribs flare, the “Big Mover” chest muscles are bullying your alignment.

• The Fix: One arm at a time lean your knees to the side to “feed” slack to the shoulder and breathe into the space. Rock back and forth as you move through your most restricted angles, controlling the slack as you go to find the right balance between floor support and fascial lengthening.

2. The “Side-Lying Arc” (Activation)

Lie on your side, top arm straight on your hip. Raise the arm until your shoulder joint is at 90 degrees and your arm is parallel to the floor in front of you (not towards the ceiling).

• The Challenge: Rotate the arm from the shoulder (thumb to ceiling, then to floor). Leading with your thumb rotated upwards, raise your straight arm until it’s vertical and then lower back to that 90 degree, parallel to the floor position.

• The Feel: You should feel it deep in the back of the shoulder blade, not the top of the arm.

3. The “Goalpost Lift” (Endurance & Calibration)

This is the ultimate test of whether your Biological Gyroscope can handle “chatter” and movement. By using both arms at once, you’re forcing your brain to coordinate stability across your entire upper back.

• The Setup: Stand tall, holding a light resistance band looped around both wrists. Bend your elbows to 90 degrees and tuck them into your ribs (your arms should look like the letter “U”). Create just enough tension on the band so your forearms are perfectly vertical—like two goalposts.

• The Move: Maintaining that 90-degree bend and constant outward tension against the band, slowly raise both elbows up toward shoulder height. Think of it as a slow-motion elevator ride for your arms.

• The Tell: Watch yourself in a mirror. As your elbows rise, do your hands want to cave inward toward your nose?

• The Meaning: If the “goalposts” collapse inward, your Big Movers (Deltoids) have taken over the lifting, and your Gyroscope (the external rotators) has stopped centering the joint. If you can keep the posts vertical all the way to the top, your software is elite.

4. The FMS Reach (The Stress Test)

Make fists with thumbs inside. Reach one arm over and one arm under behind you, trying to touch knuckles behind your back.

• The Goal: Fists within one hand-length of each other. A massive gap or lopsidedness means your “Suspension Bridge” is out of balance.

The 30-Second Fix

If any of these movements felt “hollow,” clunky, or shaky, don’t reach for a heavier weight. Add precision. In track cycling, a mechanic who over-tightens a bolt isn’t “stronger”—they’re a liability. The same goes for your shoulder. A staff team that’s “screaming” with unnecessary effort creates drag and fatigue. You want a crew that is strong enough to match the demands of the athlete, but quiet enough to stay out of the way. You are looking for efficiency, precision, and endurance.

Doing 30 seconds of the Snow Angel or the Side-Lying Arc twice a day and progressing to more complex motor control training is how you “debug” your movement code. You aren’t just building muscle; you’re training your internal staff to show up at the right millisecond, with the right amount of force, to keep the “golf ball” perfectly centered.

When your staff operates with this level of quiet competence, the “Big Movers” can finally stop playing bodyguard and get back to their real job: generating power.

The Return to Flow

Back to Mike. While he eventually chose surgery for his specific case, his recovery wasn’t about the stitches—it was about the rehab. He’s back in the pool now, reaching for that top-shelf coffee mug with the quiet power of a centered joint. Our athlete is still in the thick of it, but they aren’t just “resting”—they are retraining their Biological Gyroscope and making steady gains.

Our staff team has also used the end of our competition to pause and reflect. We are constantly asking how we can improve the accuracy of our actions and the effectiveness of our small team by leveraging our different talents. We want to be the precise, invisible force that makes the fast riders faster.

How did your cuff do in the screenings today? Are you unintentionally training just the Big Movers, or are you looking after the Gyroscope too?

Summary: The Rotator Cuff Cheat Sheet

If you remember nothing else, remember the Two As. Your shoulder isn’t a “fixed” joint; it is a high-speed, 100-update-per-second conversation between your brain and your muscles.

1. Alignment

• The Goal: Keep the “Golf Ball” centered on the “Postage Stamp.”

• The “Why”: If your chest is tight (the forward slouch), the rotator cuff is mechanically “locked out.” It physically cannot fire correctly because the “gears” are out of place.

2. Activation

• The Goal: Wake up the “Biological Gyroscope.”

• The “Why”: You don’t need heavy weights; you need precise signals. Training the cuff is about teaching the autopilot to stay engaged so the “Big Movers” can do their jobs.

Your 30-Second “Insurance Policy”

• The Morning Reset: Snow Angels (30 seconds) to recalibrate your alignment and open the chest after a night of sleep.

• The Afternoon Reboot: Side-Lying Arcs (30 seconds) to refresh the software and wake up the back of the shoulder after hours of sitting, typing, or driving.

A Call to Action for Your Cuffs

We spend thousands of hours training our Big Movers—the muscles we see in the mirror. But the longevity and power of your movement depend entirely on the Biological Gyroscope working in the shadows.

Give the Snow Angel or the Side-Lying Arc a try right now. Did you find a “glitch” in your software? Leave a comment below and let’s talk about it—your mystery ache might just be a gyroscope on strike. You can change it.

If you’ve felt this before, you know the mental spiral that comes with it. The restless nights trying to get comfortable. The concern when it shows up after a walk, a ski day, a bike ride. The quiet fear that something fundamental has changed.

In today’s post, I want to do two things clearly and honestly:

1. Help you diagnose the true source of activity-related buttock pain, and

2. Show you how to restore that tissue to something quietly capable and trustworthy again, without guesswork or unnecessary rest.

You’ll learn how to avoid babying this injury and how to understand it well enough to load it correctly.

Why these injuries show up more often as we age

I spend a lot of time solving soft tissue problems and understand the unique challenges we face as aging athletes. Muscle and tendon strains aren’t exclusive to athletes over forty, but they do become more common and more confusing as we accumulate years of training, living, and adapting.

That’s not a character flaw. It’s physiology.

I want to delve into this briefly because we’ll use the same strategies shared below for other injuries we’ll cover further into the publication and I want you to understand. Soft tissue changes are one of the core challenges we face as aging athletes.

So what happens?

When researchers compare injury patterns across age groups, a consistent trend emerges:

• Younger athletes tend to experience high-energy injuries: ligament ruptures, joint trauma, clear “snap” events. If there’s an overuse event it’s typically clear and obvious, and heals quickly with little additional help needed.

• Older athletes trend toward soft-tissue and tendon injuries: gradual onset pain, overuse patterns, spontaneous strains that seem to appear without a single inciting moment. Classically “i just woke up with it”, or “same activity, different day, and now it hurts” are common complaints.

The reason lives in our connective tissue and the predictable and modifiable changes it experiences as we age.

Younger tissues contain a high proportion of well-organized type I collagen with strong cross-links between fibers. These tissues are strong, stiff, and resilient—until they fail, often suddenly. I think of old-school denim versus the stretch jeans we wear now: the kind you had to lie on the floor to get into and peel off at the end of the day. They didn’t give much, but they were nearly indestructible.

In the same way, younger muscles are powerful, connective tissues are robust, and the system as a whole tolerates abuse remarkably well. Like those beloved jeans that lasted for decades, it holds up—right until it doesn’t.

As we age, several things begin to shift.

• Collagen production becomes less efficient. Fibroblasts still produce collagen, but it is more disorganized, thinner, and mechanically weaker. These are not abstract changes. They have real consequences. The same structures are present, but it now takes less force to cause damage.

• Elastin content declines, reducing the spring-like recoil that once protected tissues during rapid loading. With less elastin, there is less “give” in the system and fewer small shocks absorbed along the way. Think of the suspension on a mountain bike: when it’s working, you barely notice the terrain; when it’s not, every bump travels straight into the frame.

• Advanced Glycation End Products (AGEs) also accumulate, creating non-enzymatic cross-links that make tissue feel stiff without actually making it strong.

This creates what I call the “stiff but weak paradox.”
You feel tight. Motion feels restricted. But the tissue’s ability to tolerate load has actually decreased.

Add to that:

• Reduced tendon cell turnover - we don’t make new tendon cells to replace damaged or weakened ones as quickly or productively

• Slower repair of micro-damage - the small traumas inflicted by just living and being take longer to heal

• A growing mismatch between muscle force and tendon tolerance - muscles can retain or re-develop great force production qualities, often much faster than tendon tolerance can increase leading to quietly vulnerable connective tissue if we haven’t done the prep work

• Changes in blood supply in so-called “watershed” areas such as the shoulder and achilles

And suddenly, a perfectly normal training load or activity can exceed a tissue’s current capacity.

Are these changes reversible?
Partially—and in meaningful, felt ways. That’s the good news.

You can’t rewind tissue age entirely. But you can change tissue behavior, structure, and resilience at any age if you apply the right signals in the right proportions.

When a close friend recently strained her hamstring high near the buttock, her questions were exactly the ones I hear in the clinic every week. I’ll answer them below and we’ll use this opportunity to look closely at this specific injury and at the broader principles underneath it—principles that apply not just here, but to nearly any soft-tissue injury that shows up as we keep training and living. This way you’ll have a rough template you can begin to apply to your own twinges aches and pains.

When this kind of pain appears, the questions I hear are usually very practical:

• Should I be stretching this?

• How long does recovery usually take if there was no obvious tear?

• Should I stop biking or skiing if I feel it during activity?

• Is massage helpful—or could it make things worse?

Before answering any of those, let’s take a look at the specific tendon involved and how we diagnose it. Everything that follows depends on treating the right structure.

Diagnosis: Glute or High Hamstring?

This injury can be confusing. The pain sits in just the right place for a glute tendon insertion injury, and it often hurts simply to sit on—something we don’t usually associate with the hamstring.

When most people think “hamstring,” they picture an athlete sprinting across a field or down a track, suddenly pulling up in agony, hand clamped to the back of the thigh. They don’t picture someone rubbing their sit bone like they’ve sat on a thumbtack, or subtly shifting their weight during a long car ride or flight, trying to escape a deep, nagging ache.

And yet, that presentation fits a high hamstring strain remarkably well. As you’ll see, there are several clear factors that help us dial in the diagnosis and make sense of why this injury feels so different from what we expect.

So why NOT the glute? The gluteus maximus is the largest muscle in the human body. It’s short, powerful, and designed for explosive force over a relatively small range of motion. True overuse strains of glute max are very rare. It’s just too powerful and we don’t typically do heavy things accidentally in the ranges where it’s weakest (hip full flexed or full extended).

The other smaller gluteal muscles — glute medius and minimus — do strain, but when they do, pain tends to show up along the side of the hip, often toward the front of the pelvis, not deep at the base of the buttock where you sit.

High hamstring tendons, on the other hand, are a perfect storm:

• Long, slender tendons

• Crossing two joints

• Loaded heavily during acceleration, deceleration, and forward lean

• Vulnerable to age-related collagen changes

Deep buttock pain that worsens with running, skiing, sudden accelerations, or changes in direction?
Gradual onset soreness without a single “pop”?
Pain that’s aggravated by sitting, hinging, or long strides?

That profile fits proximal hamstring strain far better than a glute injury.

Once the diagnosis is clear, the path forward simplifies.

Treatment: What actually restores hamstring resilience

To come up with the best and truly transformative rehab plan we can lean on decades of work from sports where hamstring injuries are common and costly. Soccer alone has driven enormous investment into understanding what actually reduces recurrence and accelerates healing, and those principles will apply just as well to us when we adjust the load and the recovery timeframe expectations.

From that body of work, several core principles emerge consistently.

1. Start loading early — gently, but deliberately

It is safe — and beneficial — to begin isometric loading within 2 days of a strain.

This may be a surprise to many. Studies comparing early loading (within a few days) to delayed loading consistently show faster overall recovery and better tissue organization when loading starts sooner. And this is not a small effect, the time to return to sports is significantly faster when we start sooner.

I’ve been in practice long enough to remember learning the classic three stages of recovery. If you’ve taken any physiology, you may remember them too: acute (3–5 days), sub-acute (5–21 days), and chronic (21+ days).

For a long time, this was the roadmap. We predicted healing based on calendar days from injury and made decisions accordingly. It made a certain kind of sense to wait until the acute and even the sub-acute phase had passed before introducing meaningful load.

If that’s been your mental model after a strain, it’s time to update the software.

• Repeat 4 times

• Perform 1–2x/day

Gradually work into longer muscle lengths by increasing knee extension.

Pain should not spike after these contractions. Mild discomfort that settles within 20 minutes is acceptable and expected.

DO NOT SKIP THIS EXERCISE! Doing isometrics can sometimes feel like watching paint dry, but stay diligent and do them. In the early stages they are simply the safest way to introduce and increase load on your body and to scale the load up to the point where it matters and where you can begin to add more dynamic movements.

2. Progress toward hip-dominant strength

As tolerance improves, transition to hip-centered loading. Since the hamstring crosses two joints, the hip and the knee, it functions to control both joints. Hip-centered loading simply means doing motions that are generated or directed by the hip rather than the knee. This group of exercises will include:

• Hip thrusts

• Bridges

• Romanian deadlifts

• Split squats or lunges (as tolerated)

The goal here is not fatigue. It’s restoring force transmission through the hamstring–glute complex.

Since this is a high-hamstring injury we’re fixing, these hip-dominant moves are even more important.

3. Add knee-dominant hamstring work

Since most activities also involve the use of both the knee and hip, it’s important to include at least some knee-dominant strategies to strengthen the entire kinetic ‘chain’. Ignoring one end of the muscle leaves you vulnerable.

Effective options include:

• Supine ball bridge curls

• Slider curls

• Assisted Nordic hamstring lowers (if appropriate)*

*Nordics are powerful but demanding. They’re not mandatory early, and they’re not a badge of honor if the strain is simply too high.

4. Reintroduce general conditioning intelligently

If tolerated:

• Light jogging

• Uphill hiking

• Low-intensity cycling

Avoid aggressive accelerations and direction changes until strength work and jogging feel stable, even if mild soreness persists.

Use a symptom-based progression:

• Mild soreness during activity is acceptable

• Symptoms should not worsen and should settle within ~2 hours

The high-impact levers that matter most

This is where errors of omission and proportion matter most.

For active rehab-minded adults with good self-care habits, much of what I do in the early stages of the diagnosis is to fix these errors.

An error of omission means you’ve simply neglected to include an important step or rehab mix ingredient, like isometrics.

An error of proportion means you’ve been doing the right things but with the wrong priorities or focus, for example spending lots of time and energy on massage and passive modalities and breezing through the exercises without making sure you are consistent or are ramping up the intensity progressively.

Make sure you are putting these ingredients together in the right relative dosages for the best results. Here’s a diagram with common interventions and their relative power to transform you from restricted to radiant:

High-Load Resistance Training (HLRT)

Relative Power: ⭐⭐⭐⭐⭐

• 1–2 sessions/week

• ~80% of max capacity

• 5–8 reps

This is the most potent signal for reorganizing collagen and restoring tendon stiffness.

The catch: you must build toward it thoughtfully.

Examples: Hip thrusts, split lunges, dead lifts, bridges and nordics.

Eccentric-Focused Training

Relative Power: ⭐⭐⭐⭐☆

Slower lowering phases (3–5 seconds) exploit preserved eccentric strength and strongly stimulate tendon remodeling.

Examples: A ball bridge with a slow “roll-out” - letting your knees lengthen under tension for a knee-dominant move, and a slow forward single leg tip (aka a single leg RDL or “Tippy Bird”) with a dumbbell in your hand for a hip-dominant move.

Strength Training Over Stretching for Flexibility

Relative Power: ⭐⭐⭐⭐☆

Full-range strength training improves mobility and protects the new range.

Stretching alone improves sensation, not structure.

Example: The RDL is a great example of a move that can take your hamstring through a full range of motion. Do this instead of stretching and compare how you feel.

Nutritional Strategies: Collagen + Vitamin C (Adjunct)

Relative Power: ⭐⭐⭐☆☆

• 5-15g collagen

• 50mg vitamin C

• ~60 minutes before loading

Helpful, not essential. Some good evidence that supplementation improves collagen synthesis and health and shouldn’t be missed however exercise is still the main signal.

What about massage?

Massage and neuromotor techniques are valuable adjuncts, not foundations.

Used well, they can:

• Reduce pain and threat

• Improve movement confidence

• Improve neuromuscular organization and self-use

• Improve fluid dynamics and ease of motion

But early in healing, new collagen is fragile. Aggressive or poorly timed soft-tissue work can disrupt repair rather than support it. This is where injury timelines matter. Choose therapists who understand them.

I’ll admit something here: I love hands-on work. Whether I’m doing a cycling-style deep tissue session or guiding a neuromotor-focused Feldenkrais lesson, I find manual work deeply valuable and often transformative. It creates ease, clarity, and a sense of reconnection with the body that is hard to replicate any other way.

Still, this is where I see a common and costly error of proportion.

Hands-on work can make things feel better quickly. But if we lean on it too heavily, the tissue itself hasn’t changed enough to tolerate full load. That gap—between how good things feel and what the tissue can actually handle—is where re-injury happens and the downward spiral begins.

Do the soft-tissue and neuromotor work. Absolutely.
Just don’t let it replace the loading that actually restores resilience.

Should you stop activities that make you sore?

Not automatically.

High-speed, high-force movements should pause until baseline strength returns. That means high intensity running and sprinting, moves that require fast cutting or sudden changes of direction (this could be pickleball depending on your level - sorry!) or activities with inherent jumping (like many community exercise classes)

Low-to-moderate conditioning is extremely helpful if symptoms remain stable. Light to moderate intensity cycling is perfect, as is nordic skiing, walking and even easy jogging.

Avoid fear-based rest. Respect symptoms without surrendering capacity. From day one of an injury, you have two important jobs.

Healing the current injury is the obvious one. The second is easier to overlook: digging yourself out of the reduced-activity hole. The faster you recover, the less you need to modify your life. And the more strength, function, and control you maintain along the way, the less ground you have to reclaim later.

Closing: restoring trust in your body

High hamstring strains are unsettling because they sit at the crossroads of movement, power, and vulnerability. As tendon injuries, they often take appreciably longer to recover than muscle strains.

But they are also deeply trainable injuries.

With the right diagnosis, early loading, and progressive strength, these tissues don’t just heal — they adapt. You can make them stronger and more injury-proof than they were before.

This template works for most if not all soft tissue injuries. Do the right activities, include these ingredients and proportian them appropriately and have the confidence you are creating the right signals and the right environment to heal yourself.

The goal isn’t perfection.
It’s quiet competence.

It’s faith that these methods do work and they’ll work for you.

A hamstring you don’t think about.
A stride you trust again.
A body that feels capable, not fragile.

That’s the work.

For Tomas, the combo was:

• Gripping

• Elbow tension

• Finger movements

• Light wrist twisting during rasgueado techniques (that fast rolling strumming technique)

  

This is the same recipe you’ll find in climbers, carpenters, tennis players, golfers, keyboard warriors, and weekend wrench-turners. He reached out after seeing some of my elbow rehab videos, and over the course of an hour we built a program to help him reset, recover, and rebuild.

And he’s not alone. Many people have had, currently have, or will have this issue. Tendinosis is notoriously stubborn when the pain has been around a while. I’ve had patients come in strapped, taped, braced, and hurting after months of frustration.

But you can fix this. Let me show you how.

What’s actually going on in your elbow?

The muscles that move your wrist and fingers originate in your forearm. You can confirm this yourself: squeeze the muscle bellies just below your elbow and move your fingers, you’ll feel the entire forearm come alive.

• The back of the forearm houses the extensors—responsible for lifting your fingers and extending your wrist.

• The front houses the flexors—your gripping and wrist-bending crew.

• Both sides house important rotators—responsible for twisting and turning movements.

Both front and back groups converge at broad attachment sites on the elbow, either the lateral or medial epicondyle. Many muscles, one small landing zone. That’s why so many different tasks can trigger the same pain.

The problem recipe

When we do more than we’re adapted for, we cause microdamage, tiny fiber disruptions that normally heal in hours to days. But if we reload too soon, we stack new micro-injuries on top of old ones. Over time, the tissue becomes weakened, disorganized, and irritated. The brain steps in with a protective message:

“Danger. Don’t move.”

Helpful in theory, but flawed in reality because tendons must be loaded to heal.

Healthy tendon fibers look like uncooked angel hair pasta, long, organized, parallel strands designed to transmit force. Overloaded tendon fibers look like a sticky lump of cooked spaghetti. The repair tissue is immature and disorganized. The only thing that realigns those fibers into strong, efficient rows again?

Graded load. Not rest. Not stretching.
Progressive, targeted loading.

So let’s get into the plan.

The Elbow Tendinosis Protocol

This is the exact starting program I use in the clinic and one that’s well-supported by research. Start here, then layer on additional work depending on sensitivity and goals.

1. FlexBar Tyler Twist (Primary Treatment)

This is the cornerstone of eccentric loading for lateral elbow tendinosis.

How to Perform

• Start with the red FlexBar (light). If that feels too easy, move to green.

• Stand tall, shoulders relaxed.

• Hold the bar in both hands with your affected hand palm down.

• Use your unaffected hand to twist the bar toward you.

• Then slowly** untwist with the affected hand**, resisting the movement. That slow lowering is where the magic happens.

Sets & Reps (research-backed):

• 3 sets x 15 reps

• 1–2x/day

• Slow, controlled lowering (2–4 seconds)

Goal: pain ≤ 4/10 during, easing by the next day.

2. Accessory Strengthening (Support the Tendon)

Your tendon will respond better when the surrounding muscles are conditioned, too.

Hammer Rotations (Pronation/Supination)

• 3 x 12–15 reps

• Hold the handle close to the end to increase load.

Dumbbell Wrist Flexion / Extension

• 4 x 12 reps (hypertrophy zone)

• Use slow tempo, 2 sec up, 2 sec down

• Perform on both flexors and extensors.

Isometric Pinches + Carries

(Holding a plate, pinch block, or dumbbells)

• 3 x 30–45 seconds

• Pain-free or mild discomfort only.
  Great for early-stage pain reduction.

3. Don’t Miss These (They Matter!)

Kinetic Chain Strength

Shoulders + mid-back + core = power distribution. If these areas fatigue early, the elbow takes the hit.

Add:

• Rows or band pulls

• Scap stabilizers

• Rotator cuff control work

Lifestyle “Level-Uppers” for Healing

These surprise people:

• Stop smoking if you smoke—tendons hate nicotine.

• Sleep position matters: if you curl up and pin your elbows in deep flexion all night, you’re feeding the irritation cycle.

• Rest & nutrition—both absolutely influence tendon healing.

Should you keep doing your activities?

• Elective activities (tennis, climbing, playing guitar for fun): reduce volume or take a short break during early healing.

• Non-negotiable activities (your job): continue, but supplement with:

  • massage

  • heat/ice

  • forearm strap (temporary relief, not a fix)

Just remember: the only path to healing is exercise, not gadgets.

4. When to Get Additional Help

It can take a few weeks of consistent loading before your nervous system stops yelling. That early-phase sensitivity is partly protective brain behavior and partly the proximity of a very sensitive nerve on the lateral elbow.

If you’re doing the program consistently for several weeks and still not seeing progress, consider:

• professional PT evaluation

• imaging (rarely needed)

• guided injections (if indicated)

• nerve assessment if symptoms include burning or spreading

Most people don’t need anything beyond the program above—but guidance accelerates the process.

Research Spotlight: Why Progressive Loading Works for Elbow Tendinosis

Tendon pain improves when we load the tendon—slowly, progressively, and consistently.
Here are several key studies supporting the exact approach used in this program:

1. Eccentric loading reduces pain and improves function

Tyler et al., 2010

• In a randomized controlled trial of 21 patients with lateral epicondylosis, incorporating the Tyler Twist eccentric protocol produced significantly greater reductions in pain and improvements in strength compared to standard therapy.

• The FlexBar group showed a 22% greater improvement in Disabilities of the Arm, Shoulder, and Hand (DASH) scores.

2. Tendon remodeling requires load—not rest

Kjaer et al., Journal of Applied Physiology, 2009

• Demonstrated that mechanotransduction (how tendons sense and respond to load) is the critical driver of collagen alignment and tendon regeneration.

• Unloaded tendons deposit disorganized collagen; appropriately loaded tendons lay down strong, parallel fibers.

3. Isometric loading reduces pain and increases tendon capacity

Rio et al., British Journal of Sports Medicine, 2015

• Showed that isometric contractions can reduce tendon pain by altering cortical inhibition.

• Holds of 30–45 seconds reduced pain acutely and improved force output.

4. Forearm/wrist strengthening outperforms passive treatments

Struijs et al., American Journal of Sports Medicine, 2004

• Compared physiotherapy including wrist extensors strengthening vs. corticosteroid injection and “wait-and-see.”

• Active strengthening had better long-term outcomes at 6 and 12 months.

5. Proximal strength affects distal tendon load

Lucado et al., JOSPT, 2019

• Found that deficits in shoulder and scapular strength increase strain on the wrist extensor tendons by up to 25–30% during gripping activities.

• Reinforces the value of kinetic-chain strengthening—rows, cuff work, and postural stabilizers.

Takeaway

The strongest evidence consistently supports a program built around:

• Eccentric loading (Tyler Twist)

• Targeted wrist flexion/extension strength

• Isometrics for pain modulation

• Kinetic-chain strengthening

• Progressive load—not rest—as the driver of healing

This is exactly the approach Tomas used… and exactly the one you now have at your fingertips.
