"I've spent years working with women 40+ whose joints kept fighting every workout they tried. Most of them weren't lazy. They were scared — of their knees, hips, back, or shoulders blowing up again.
I became a Certified Muscle System Specialist (MSS) so I could understand how the muscular system, joints, and nervous system interact, and build plans that respect that.
Theorem isn't a bootcamp or a big-box gym. It's a Strength & Longevity Lab for women 40+ with joint issues who want to stay strong, independent, and active for the next 10–20 years, not just survive the next challenge."

"I can’t say enough great things about Theorem Fitness! Dominick is truly committed to his clients’ success and it shows in everything he does. I’ve been working with Dom for 8 months and he has helped me reach my goals and beyond."
Stacie Johnson
"My experience at Theorem Strength & Longevity has been exceptional. Within the first couple weeks my joint pains were reduced to little to non-existent. I feel stronger in my body which was something I was afraid I would not feel again after entering my 50s. I am so glad I chose the lab to reach my health goals."
Shannon Rizzo
"Dom is such a great motivator and knows how to keep you accountable each week. Dom loves what he does and it shows! I lost the weight, am in less pain day to day and even getting that daily protein in 💪🏼 I feel great and have Theorem Strength & Longevity to thank!"
