Notes On Midlife Fitness

Many patients (and 32% of you in the survey) told me they didn't have time to exercise… we can fix that. This episode shows that fitness doesn't require an hour, a gym, or a change of clothes.

Two to three minutes of movement, repeated throughout the day, changes your metabolism more than a single workout followed by six straight hours in a chair. I explain exactly why, along with what it actually looks like to build this into a normal day.

After 40, most people notice the same pattern: recovery takes longer, strength and power fade, body composition shifts, joints get cranky, and the training that used to work stops working. Most are told this is just aging, and there’s not much you can do.

I disagree. This guide explains what is actually changing in midlife physiology and the specific levers that can change the trajectory: muscle mass, power, bone density, joint health, hormones, metabolic health, recovery, protein, sleep, and more. The framing is simple: decline isn't inevitable, as most people think. The biology still responds. You just have to give it the right signal.

A missed workout won’t derail your fitness, and even a few weeks away rarely erase the progress you’ve built. What often disappears much faster is momentum.

In this episode, I talk about my own recent issue, as well as a patient whose minor hamstring injury healed within weeks… but whose training routine didn’t recover nearly as easily.

We’ll discuss why interruptions can feel so much bigger than they actually are, why protecting your routine matters as much as building it, and how to start showing up again after injury, illness, work, family, or life gets in the way.

For those of us training in midlife, the goal isn’t a perfect streak. It’s developing a routine resilient enough to survive the inevitable interruptions—and learning how to pick it back up when they occur.

Robert showed up to his last appointment with a ring that tracks his sleep, a watch that scores his readiness, and a printout of a ‘metabolic’ supplement stack he wanted my opinion on. This was just before he admitted that he had not walked much, or lifted anything heavier than that printout in front of him in four weeks.

People do not decide their futures… they decide their habits. And their habits decide their future.

This episode is about why the boring things— the walking, the two days in the gym, the consistent bedtime— will always outperform nearly every hack on the market. And that is exactly the reason the wellness industry will never stop inventing new ones.

Check out the Guide Bundle (3-in-1) I put together that’s related to this topic. Midlife athletes are constantly sold isolated, ineffective solutions: A new recovery tool, a tendon supplement, a training hack, a single biomarker, or a protocol promising to reverse aging… the list goes on and on. And most of that misses the point: Staying capable requires a simple, repeatable, and borderline boring system.

This bundle brings together three practical guides covering how to structure training, how to understand and manage tendon pain, and how to interpret the metabolic markers that influence long-term health. It is designed for athletes who want to keep showing up, protect what allows them to train, and make better decisions about how they age.

Welcome back to Note on Midlife Fitness. I'm Dr. Howard Luks, an orthopedic surgeon, and this is the show about what actually keeps you strong, independent, and out of my operating room. This week, we're talking about why movement was never really about fitness in the first place and what stillness is quietly costing you at the cellular level, long before you'd notice.

You're waiting for the right day, the right program, or the right pair of shoes to start. You don’t need to… let’s get into this.

Because… Here's what the research shows: the biggest leap in longevity gains doesn't come from training like an athlete; it comes from going from nothing to something.

In this episode, I explain why stillness isn't a neutral state but active harm, measurable at the cellular level years before it ever shows up on a standard lab test, and why ten minutes today will do more for you than the perfect program you keep putting off.

No gym required. Just a pair of shoes and ten minutes.

If you have knee osteoarthritis, this guide will tell you what most physicians do not have time to explain in a fifteen-minute office visit:

Written by Howard Luks, MD, an orthopedic surgeon with thirty years of practice, the guide covers what knee osteoarthritis actually is, why your X-ray does not determine your future, why metabolic health drives a large share of the pain and progression, the supplements with real evidence (and the ones without), what GLP-1 medications are doing for OA pain, when injections help and when they do not, why strength training is one of the most effective interventions available, and how to think honestly about surgery. The framing throughout is that you have more agency than the standard conversation gives you. No fluff. No fear. The levers you actually have, in a guide you can read in an hour.

The wellness industry thrives on making us feel like we’re always falling behind. More tracking. More supplements. More gadgets. More optimization.

In this episode, I make the case for a different word: enough.

If you’re walking regularly, lifting a few times a week, sleeping reasonably well, eating real food, and staying connected to people who matter, you’re not doing the lesser version of health. You’re doing the things that actually matter.

We explore the difference between fundamentals and fitness theater, why consistency beats complexity, and how learning to say “enough” to both the pressure and the noise can be one of the healthiest decisions you make.

Sometimes the most powerful health strategy isn’t adding something new. It’s realizing you’re already doing enough.

GLP-1 medications are advertised as weight loss drugs. Yet they are so much more than that, and there are important factors you should consider before you decide if they’re right for you.

What do you need to know before you start? What lab tests or studies should you check before and during the treatment? What is the concept of the minimal effective dose, and why does that help to minimize side effects? This guide answers a lot of the questions and concerns you might have about this new class of powerful medications.

Everywhere you look, someone is selling you ‘longevity’. Live longer, add years, hack your biological age. Most of them are aiming at the wrong target. Living longer means very little if those extra years are spent unable to move well, think clearly, or take care of yourself.

We have gotten good at extending lifespan, the length of the movie, while healthspan, whether the movie is any good, has barely moved.

In this episode, I make the case for the goal that actually matters: the strong, sharp, independent years. I'll show you the simple signals that predict how you're aging better than any expensive lab, why you can't really turn back your biological clock, and why the people who age best have a certain rhythm.

Episode 3 — You Are Not Falling Apart

We have spent so long warning people about the dangers of moving that we have forgotten to warn them about the dangers of staying still. And stillness is the far more reliable source of harm. When you do less, your body loses more, and it loses it quietly: muscle, bone, balance, cardiovascular fitness, insulin sensitivity. After 50, if you’re not training, you lose one to two percent of your muscle every year, and your power fades faster still. Falls, frailty, and dependence don’t simply happen to people. They build in silence, in the absence of motion, until one day they aren’t silent anymore. In this episode, an orthopedic surgeon of thirty years on why most of what we call aging isn’t aging, and why the body you’re afraid of breaking is far more capable than you’ve been told.

Episode Title

Labral Tears After 40: Why Your MRI Is Lying to You

Podcast

The Three BoneheadsHoward Luks, MD · Jeffrey Berg, MD · Jonathan Hirsch, MD

Episode Summary

If you’re over 40 and have shoulder pain, there’s a very good chance your MRI report mentions a labral tear. And there’s an even better chance that tear has nothing to do with your pain.

In this episode, three experienced orthopedic surgeons unpack one of the most common—and most misunderstood—MRI findings in adult shoulders: superior labral (SLAP) tears. Drawing on decades of surgical experience, they explain why these findings are often age-appropriate, why MRIs frequently create unnecessary fear, and why surgery is almost never the right answer for adults with non-traumatic labral tears.

This is a candid discussion about judgment, restraint, and knowing when not to operate.

Key Topics Covered

1. What the Labrum Actually Is

* A 360-degree ring of tissue around the shoulder socket

* The superior labrum is where the biceps tendon attaches

* Age-related changes are extremely common and often mislabeled as “tears”

2. Why MRIs Overcall Labral Tears

* Most adults over 40 will have a “SLAP tear” reported on MRI

* Radiologists often describe normal age-related changes as pathology

* The word tear creates anxiety and drives overtreatment

* MRI findings frequently don’t correlate with symptoms

3. MRI Quality Matters More Than You Think

* 3-Tesla MRIs are far more accurate than 1.5-Tesla scans for labral pathology

* Contrast (arthrograms) improves detection but is invasive and often unnecessary

* Fellowship-trained musculoskeletal radiologists provide more reliable reads

* Not all MRIs—or interpretations—are created equal

4. When a Labral Tear Actually Matters

* Rare in adults without trauma

* More relevant after:

* Shoulder dislocation or instability

* Clear traumatic events

* Clicking, catching, or mechanical symptoms alone are not enough to justify surgery

5. Why Labral Repairs in Adults Often Fail

* High risk of post-operative stiffness and prolonged pain

* Long recoveries with questionable benefit

* Literature consistently discourages SLAP repairs in patients over age 40

6. What Surgeons Actually Do If They See a Tear

* Most labral findings are ignored during surgery

* Minor fraying may be gently debrided (“a haircut”)

* If the biceps is truly involved and symptomatic, biceps tenodesis is preferred

* True labral repair is exceedingly rare in adults

7. The Real Sources of Shoulder Pain

* Subacromial bursitis

* Rotator cuff tendinopathy (without a tear)

* Age-related tissue changes

* Many people improve without ever identifying a single structural cause

8. Why Time and Re-Examination Matter

* Shoulder diagnoses often evolve

* Multiple visits help clarify what actually provokes pain

* Healing, physical therapy, and patience often outperform early surgery

* Sometimes the pain resolves—and the “diagnosis” never matters

Key Takeaways

* A labral tear on MRI in adults over 40 is usually a normal finding

* The likelihood that it’s causing your pain is close to zero

* The likelihood that you need surgery for it is even closer to zero

* MRIs should inform—not replace—clinical judgment

* Treat the patient, not the picture

Who This Episode Is For

* Adults over 40 with shoulder pain

* Anyone confused or alarmed by an MRI report

* Clinicians navigating imaging-driven anxiety

* Patients told they “need surgery” for a labral tear

Final Word

Sometimes the hardest part of being a surgeon isn’t operating—it’s knowing when restraint, patience, and experience are the better tools. This episode is a reminder that wisdom often means doing less, not more.

Rotator cuff tears. MRIs. Fear. Surgery.

Three words that often get tangled together—and usually in the wrong order.

In this episode of The Three Boneheads, we unpack why MRI findings often matter far less than people think, how age-related “abnormalities” are frequently normal, and why pain, function, and real-life goals should drive decisions—not radiology reports.

Please leave a comment. We need to know your thoughts about these podcasts. We would also like to know which topics interest you.

We talk about:• Why many people with massive tears have little pain—and others with tiny ones can’t sleep• How MRIs can sometimes do more harm than good• When surgery truly changes outcomes—and when it doesn’t• Why rotator cuff care should be a conversation, not a knee-jerk reaction• How rehab, load management, and time often outperform the scalpel

If you’ve ever been told, “You have a tear—you need surgery,” this episode is for you.
