Performance is for Everyone.
Located at 7600 S Grant St B3, Littleton, CO, OTG Athlete is a performance facility built for those who refuse to settle for "average." Founded by a former Division I Strength & Conditioning coach, we bridge the gap between elite sports science and everyday health.
We provide a fun, high-intensity, and supportive environment where competitive athletes and longevity-minded adults train side-by-side to reach their peak potential. At OTG, we don't just "work out"—we follow intentional, science-backed programs designed to build confidence and deliver objective results.
Elite Coaching
Train under the same rigorous standards used by Division I and professional athletes. Our coaches aren't just personal trainers; they are career strength and conditioning professionals with experience at the highest levels of sport, including the NFL Combine and collegiate athletics. You get access to the same technical expertise, movement correction, and performance insights usually reserved for the pros.
Intentional Culture
We’ve built a team-like atmosphere where every individual is pushed to grow. This is a "competitive but supportive" environment where athletes and adults hold each other to a higher standard. At OTG, you aren’t just another person on a treadmill; you are part of a community that celebrates hard work, consistency, and the shared pursuit of big goals.
Proven Programming
We have a strict "no random exercises" policy. Every movement in your program has a specific purpose backed by exercise science and data. Our programming is structured and progressive, meaning we track your development over time to ensure you are actually getting faster, stronger, and more resilient, rather than just getting tired.

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.
Can you help with sport-specific training for my child?
Yes. Our Sports Performance program focuses on building the foundational speed, power, and agility required for any sport. We customize the approach to fit the individual athlete’s needs, helping them improve their competitive edge.
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.
