My goal is simple: help you build the physical capacity to fully enjoy the life you’ve worked so hard to create.

I’m a PhD Physiologist who's helped hundreds of successful men build the strength, fitness, energy and resilience needed to perform at a high level today and stay capable of doing what they love for decades to come.

I build personalized performance systems for men in their 40s and 50s that turn what they already know into a body that performs-and a life they can fully enjoy.

Hi, I'm Dr. Michael

99% of men don't move well or feel good. I'm here to help you be part of the 1%.

Let's Measure and Build your Capacity to do the things you love...for life.

This is for you if...

Your physical life no longer matches your professional life.

You train 3-4x/week, but not getting the results you should be getting.

You track sleep, HRV, calories and workouts, but you know something's missing.

You want to look strong- and actually feel strong, capable, dangerous and alive.

Your next chapter demands more than longevity.

It demands Energy, Strength, Capacity and Presence.

FitSpan Guarantee:

Improve Your FitSpan Score - or You Don't Pay.

FitSpan is the only executive performance program built around a single measurable outcome.

The FitSpan Score is the "FICO score for Health".

We track your Strength, Engine, Recovery and Resilience. If your score doesn't improve, Dr. Donovan will coach you for FREE until it does.

Dr. Donovan built his career on the science of performance. If you do the work, adaptation is guaranteed.

Most performance coaches are experienced trainers. That's not what you get with here. Dr. Donovan spent years as a scientist at NIH, studying behavior change and physiological mechanisms behind human performance - then spent the last decade applying that science to real men with real schedules, real stress loads and real stakes.

The FitSpan methodology isn't built on convention. It's built on what data actually shows about how a man's body responds to training stress in midlife. There isn't another program in this space with that combination. That's not marketing, it's just true.

Rooted in Physiology. Built for Durable Performance.
