From the NFL to
Your Corner
I didn't start Key Body & Fitness to sell workouts. I started it because I've spent 32 years learning what the human body is truly capable of — and I believe everyone deserves access to that knowledge.
From playing three seasons with the New England Patriots, to competing as a K1 professional kickboxer and IFBB pro bodybuilder, I've trained at the highest levels. My degree in Kinesiology from the University of Michigan gave me the science. The arena gave me the experience.
Today, I bring that same elite-level approach to busy professionals over 40 who want to move better, feel stronger, and live longer. No fads. No shortcuts. Just proven, personalized programming that works.

Stories That Speak
"At 70 years old, after surviving a heart attack, I never thought I'd feel strong again. David didn't just give me exercises — he gave me my life back. His understanding of the body at my age, his patience, and his science-based approach made all the difference. I'm stronger now than I was at 60."
