Monstrousitous Combat Conditioning Manual + Consultation with Jeff - Monstrousitous Strength and PerformanceMeet Coach Jeff Lee

Coach Jeff Lee has spent two decades building stronger humans. As the founder and head coach of Monstrousitous Strength and Performance, he’s worked with Olympians, collegiate athletes, high school athletes, and world champions in Muay Thai, Jiu Jitsu, and MMA.

But he’s just as invested in the 40-year-old dad chasing his edge as he is in the 24-year-old fighter chasing a belt.

Jeff created Monstrousitous Strength and Performance to deliver battle-tested strength and conditioning programs that help anyone—from top-tier athletes to everyday grinders—build powerful bodies and bulletproof mindsets.

What We Stand For:

We believe that discipline beats motivation, and that strength is about more than lifting weights—it’s about showing up when it’s hard, getting uncomfortable on purpose, and becoming someone you’re proud of.

You don’t need to be a competitive athlete to train like one.

You just need the guts to commit and the longevity to succeed.

Monstrousitous Strength and Performance is here to show you how.

Train with intent.  Perform with Purpose.
