Performance Physiology for Physicians

Build the capacity to practice at your best - and still have something left for life.

We help physicians in their 40s and 50s measure, rebuild and maintain the strength, conditioning, recovery and resilience required to perform at a high level—without pretending you have a predictable schedule.

Led by Dr. Michael Donovan

You don't need another fitness program.

You need a performance system built around the reality of practicing medicine.

The Flaw with Most Fitness Programs

Built for Your Actual Physiology

Most fitness programs assume you have predictable hours, consistent sleep, unlimited time and a life that revolves around your health. You don't.

We start with your actual physiology, schedule and the life you actually want to live.

The goal isn't perfect health.

It's enough strength, conditioning, recovery and resilience to practice medicine and still have something left.

Become the physician who has the capacity to practice, parent, travel and play and still have something left in the tank.

We measure what determines how much capacity you actually have:

STRENGTH

ENGINE

RECOVERY

RESILIENCE

Can your body produce force when life demands it?

Can you sustain effort without getting crushed by it?

Can you adapt to stress and come back ready?

Can you keep performing when life gets difficult?

The FitSpan Score

These inputs come together in your FitSpan Score: a simple way to see where your capacity is strong, where it is leaking, what to work on next.

Analyze→ Prioritize → Optimize → Revise

Health has hundreds of metrics. Capacity has a few that really matter.

Why physicians work with me:

I'm Michael Donovan, PhD.

PhD physiology: I understand the mechanisms behind adaptation—not just fitness trends.

20+ years in health and performance: I've worked across research, public health, behavior change and applied performance.

Physician-specific coaching: FitSpan is designed around call, clinic, travel, family and the unpredictable demands of medicine.

Measured performance: We establish a baseline, identify limiting factors, intervene, and reassess.

The Physician Capacity Guarantee:

Improve Your Capacity guaranteed.

If you follow your individualized plan, complete the agreed assessments and maintain the agreed level of adherence and we don't demonstrate measurable improvement in the metrics we established:

I will continue coaching you at no additional cost until we do.
