A day-to-day guide to preventing and surviving injury
Dr. Dave Heitmann on Injury, resilience, and reprogramming your body for performance and longevity.
Most people treat injuries like setbacks—but what if they were the doorway to becoming anti-fragile? In this episode, Dr. Dave unpacks how stress, recovery, and micro-programming in 90-day cycles can not only heal pain but unlock higher performance. From Patagonia trail tweaks to pro-athlete injuries, you’ll hear why embracing damage is the real secret to longevity and strength.
Key Bullet-Point Summary
The Stress Bucket Framework – Injuries happen when physical, mental, and nutritional stress drains your “bucket” faster than you can refill it.
Three Elements of Every Injury – Chemical (inflammation), neurological (nerve firing), and mechanical (tissue movement) all play a role in damage and recovery.
Trauma Isn’t Just Bad Luck – Even so-called “freak injuries” often trace back to poor pre-programming and lack of tissue resilience.
90-Day Programming Cycles – Healing and performance both thrive on 3-month blocks: adaptation, reinforcement, and expansion.
Movement is Medicine – Micro-dosing movement and ligament flexibility training prevents breakdowns better than marathon gym sessions.
Sharp Pain vs. Dull Pain – Sharp pain means stop; dull, deep pain can signal therapeutic progress and better range of motion.
Recovery Beats Workouts – Sleep, light, and environment matter more than just copying a pro athlete’s program.
Embracing Injury as Data – Instead of fearing setbacks, use them as feedback loops to reprogram your body and come back stronger.
Programming Beyond the Gym – The other 23 hours of your day—sleep, food quality, stress management—are as important as the one hour of training.
Anti-Fragile Longevity – True performance is about becoming resilient enough to handle volatility in sport, work, and life.
Five FAQs
1. What is the “stress bucket” and how does it cause injury?
The stress bucket is a model where all forms of stress—training load, poor sleep, work, and even nutrition—drain your body’s capacity. When the bucket empties, tissues break down, leading to overuse injuries or even traumatic injuries. The solution is balancing stress with recovery strategies like sleep, nutrition, and micro-movement practices.
2. What are the three main components of injury?
Every injury involves chemical inflammation, neurological shutdown, and mechanical dysfunction. Addressing all three—using anti-inflammatory nutrition, nerve-activating therapies, and mobility drills—creates faster and more complete recovery than painkillers alone.
3. Why do endurance athletes get injured so often?
Up to 85% of endurance athletes experience foot, knee, or hip injuries because of overtraining, poor recovery, and lack of tissue flexibility. The solution is adding tissue management (stretching, fascia work), movement variety, and better sleep/nutrition habits to offset high training volumes.
4. How should I recover from a meniscus or knee tweak?
Most minor meniscus issues don’t require surgery. Recovery focuses on reducing swelling, restoring the “screw-home” rotation of the knee, and building hip and adductor stability. Micro-movements, circular knee mobilizations, and progressive strength work in 90-day cycles rebuild function while preventing flare-ups.
5. How do 90-day programming cycles improve injury prevention?
The body adapts in three phases: shock, foundation building, and expansion—each lasting about four weeks. By programming in 90-day blocks, athletes allow ligaments, tendons, and neural pathways to remodel safely. This prevents overuse injuries and accelerates long-term performance gains.

Expanded Summary
Burnout, Overachievement, and the Stress Bucket
Dr. Dave Heitmann’s journey into sports medicine and high performance started in childhood as a multi-sport athlete, but the constant collisions, broken bones, and injuries taught him more than textbooks ever could. After founding a massive sports medicine clinic with teams, gyms, and nutrition services, he hit the wall of overwork. Long hours, insomnia, Netflix-and-beer coping habits, and brain fog left him depressed and questioning if he could go on. He describes this as his burnout hell, a place where success masked collapse. The key metaphor he developed from this period is the stress bucket: every source of stress—whether from work, training, nutrition, or family—pours into the same container. Once the bucket overflows, injury and illness are inevitable.
Anatomy of Injury: Chemical, Neurological, and Mechanical
One of Dr. Dave’s core teachings is that every injury is three-dimensional. First, there’s the chemical layer—swelling, inflammation, and the body’s molecular response. Second, the neurological layer—the nervous system’s protective shutdowns, loss of muscle firing, or pain signaling. Third, the mechanical layer—the actual tissues, ligaments, and joint mechanics. Treating only one of these dimensions is why conventional approaches often fail. A twisted knee in Patagonia, for example, isn’t just a “mechanical” tear; the chemicals and neurology must be restored too. This whole-systems model makes recovery more effective than one-size-fits-all protocols.
Recovery Beyond Painkillers: Lifestyle, Movement, and Micro-Dosing Stress
Instead of relying solely on medical pain management, Dr. Dave emphasizes self-directed recovery. Nutrition plays a role (omega-3s, turmeric, anti-inflammatory foods), but so do modalities like red light therapy, vibration therapy, and direct current stimulation. He reframes pain: sharp pain is a warning to stop, while dull pain is often therapeutic and should be gently explored. Small, intentional “micro-doses” of movement—ankle rolls, knee circles, toe flexibility drills—prepare tissues to adapt and prevent future breakdowns. In this model, recovery isn’t downtime—it’s active training for resilience.
Programming Health in 90-Day Cycles
Dr. Dave applies epigenetics, neuroscience, and performance science to programming. Human tissues adapt in 90-day cycles: the first month shocks the system, the second builds a foundation, and the third refines it. Whether for Ironman athletes, CrossFitters, or executives, breaking life into 90-day “sprints” aligns with how our brains set goals and how our tissues remodel. This mindset also reframes injuries. Instead of believing an injury ends a career, a three-month cycle offers both recovery and growth. A torn meniscus or frozen shoulder becomes a training block to gain new mobility, not just a setback.
Anti-Fragile Longevity and the Fun Factor
Dr. Dave’s long-term vision isn’t just preventing injuries—it’s creating anti-fragile humans. Anti-fragile systems don’t merely resist stress; they get stronger from it. That means building habits that make ligaments, fascia, and the nervous system more resilient over decades. Equally important, he insists that fun is the ultimate performance enhancer. Athletes and entrepreneurs burn out when training stops being joyful. Switching from bodybuilding to mountain biking, or from endurance racing to kayaking, isn’t failure—it’s evolution. The endgame is longevity: a body that can still move, play, and thrive well into the 80s and beyond, not just rack up years. Injury, stress, and setbacks aren’t enemies—they’re invitations to adapt and become stronger.
Podcast Transcript: [A day-to-day guide to preventing and surviving injury]
[00:00] Introduction
Host: Boomer Anderson here. I’m in lovely Asheville, North Carolina, wrapping up what has become an epic first-quarter trip into the Americas. I’ve been in places like Asheville, Austin, San Diego, Buenos Aires, Mendoza, and El Calafate. I even tackled the W trek in Torres del Paine.
Today’s conversation is with someone I met along the way—Dr. David Heitmann. We had lunch a couple of times in Austin, and I honestly wish I had recorded those lunches. The sound quality is better this way, but you’ll see why I say that once you hear him.
Dr. Heitmann and I dove deep into movement mechanics, injury, and recovery. We also talked about stress, programming your life in 90-day cycles, and how to reframe injuries as opportunities to grow stronger. This episode is packed.
[05:00] About Dr. Dave
Host: Who is Dr. Dave Heitmann? He’s been obsessed with health and performance since childhood. A five-sport athlete growing up, he played football and rugby until 27. In college, he double-majored in biochemistry and molecular biology, doing research in biomechanics and energetics.
He went on to earn his Doctor of Chiropractic and a Master’s in Sports Science and Rehabilitation. He’s logged 600 hours of clinical exercise physiology training, is a certified strength and conditioning coach, and spent a decade running a full-scale sports medicine clinic. His resume is pages long, but more important—he lived through injuries himself.
[10:00] Burnout and Collapse
Dr. Dave: My knowledge meant nothing when my own body broke down. I was the guy who thought I could push through everything—team captain, multiple sports, rugby until 27. I had 14 broken bones, torn ligaments, shoulder separations, nerve damage, and concussions that made me black out. That pain shaped my path into chiropractic instead of an MD.
But here’s the bigger story. After five years of building a 6,500-square-foot sports medicine clinic—CrossFit gym, cycling studio, triathlon coaching, yoga, nutrition seminars—I was working 100 hours a week. I burned out hard. Insomnia, depression, brain fog, popcorn-and-beer nights just to unwind.
There was one morning driving to work when I thought: Maybe I should just drive off the road so I don’t have to show up today. That was my breaking point.
[15:00] The Dark Side of High Performance
Host: That resonates. In finance, I remember thinking the same—wondering if I could get hit by a cab just to get rest. There’s a dark side to high performance.
Dr. Dave: Exactly. My ego told me I was unstoppable, but burnout forced me to rethink everything. For years, I went through diagnosis after diagnosis: low testosterone, heavy metals, candida, gut issues. I tried chelation, antifungals, elimination diets—spent money, time, and energy. Nothing worked.
The problem? I was missing the bigger picture—sleep, lighting, lifestyle stress, and context. It wasn’t one molecule, one pill. It was my entire system.
[20:00] The Birth of the Stress Bucket
Dr. Dave: Out of that collapse, I developed the stress bucket metaphor. Everything in life pours into the same bucket—work, family, exercise, nutrition, sleep. When it overflows, you break.
Here’s the twist: stress is relative. Exercise can fill your bucket or drain it. Nutrition can heal you or exhaust you. For some people, not working stresses them more than overworking. It’s all about perception.
If your bucket is empty, every training plan collapses. You get bursitis, knee pain, hip pain. Even trauma—like a football tackle—is influenced by how prepared your tissues are.
[25:00] Anatomy of Injury
Dr. Dave: Every injury has three layers:
Chemical – swelling, inflammation, the body’s response molecules.
Neurological – nerves shutting down, muscles losing firing patterns, protective mechanisms.
Mechanical – the tissue itself, ligaments, joints, fascia.
Take a knee injury in Patagonia. You slip on a rock. First, chemicals flood the area (swelling). Second, nerves tighten surrounding muscles to protect the joint. Third, the joint mechanics get stuck. If you only address one—say, ice for swelling—you miss the rest.
[30:00] Beyond Painkillers: Real Recovery
Host: So what’s the alternative to painkillers and splints?
Dr. Dave: Recovery means attacking all three layers:
Chemical: anti-inflammatory foods, omega-3s, turmeric, photobiomodulation, sometimes peptides or stem cell therapy.
Neurological: vibration therapy to relax protective patterns, direct current stimulation (like the Neubie device), and embracing dull pain. Dull pain is therapeutic. Sharp pain is damaging.
Mechanical: micro-movements—ankle rolls, knee circles, toe flexibility drills. Ligaments need micro-dosing stress to stay resilient.
That’s how you prevent a pebble or curb from taking you out.
[35:00] Programming in 90-Day Cycles
Dr. Dave: The body works in 90-day cycles. The first month says, “What the heck is this?” The second month builds a foundation. The third refines it. Then you repeat.
This aligns with epigenetics (gene expression changes over ~90 days) and neuropsychology (the brain can realistically focus on 90-day goals). It’s also how we reframe injuries.
Instead of saying, “My knee is ruined forever,” you say, “Let’s rebuild it for three months.” Injuries become opportunities to reset programming.
[40:00] Anti-Fragile Humans and Fun as Performance
Host: What’s the bigger goal?
Dr. Dave: Anti-fragility. Not just resisting stress, but getting stronger from it. That’s how ligaments, fascia, and the nervous system evolve.
And here’s the piece most people forget: fun is the ultimate performance enhancer. If training isn’t joyful, you’ll quit. Switching from bodybuilding to mountain biking isn’t failure—it’s growth. Injuries, stress, setbacks—these are invitations to adapt.
I’d rather live to 85 with full mobility, playing with my grandkids, than crawl to 95 in a chair. Longevity is about quality of healthspan, not just years.
[45:00] Final Takeaways
Dr. Dave: Everyone should think of life in three-month blocks. Whether it’s healing an injury, chasing a race, or learning a new skill, 90 days gives you focus and hope.
Host: That’s brilliant. I love how you reframe injuries into growth.
Dr. Dave: If health is a journey, then every setback is just a side trail that makes you stronger.
