Founded by a former Division I Strength & Conditioning coach, we’ve taken the best of elite sports science and simplified it into a welcoming, practical program for real people with real lives.

Proven Programming

Frequently Asked Questions
I’m not a professional athlete. Is OTG Athlete still right for me?
Absolutely. While we use elite-level training principles, our Adult Performance program is specifically designed for adults over 35 who want to train with purpose. We meet you where you are and scale the intensity to your current ability.
What makes "Performance Coaching" different from a standard gym workout?
Most gyms give you a list of exercises to get you tired. We provide intentional programming designed to make you better. Our coaches have collegiate and pro-level experience, ensuring your training is progressive and science-backed.
How do I get started and which program should I choose?
Every journey at OTG starts with a Discovery Call. We’ll discuss your goals, injury history, and schedule to help you decide between our Sports Performance or Adult Performance programs.
