Welcome to TRAIN, Denver’s premier private workout and training facility located in downtown Denver in the Historic Ballpark Neighborhood. We offer boot camp, personal training, boot camp and HIIT!



TRAIN was born from a love of athletics, a fascination with science, and a desire to teach and motivate people to lead a healthy lifestyle. TRAIN specializes in high-quality personal training, boot camp, HIIT and group fitness. We are not Crossfit. We offer safe, effective workouts based in scientifically proven methods. Whether you join one of our nationally-recognized HIIT/boot camp classes, or train one-on-one with a personal trainer, our programs focus on functional fitness for a wide range of fitness levels. We coach all of our sessions to increase cardiac output, add strength, create symmetry, improve movement quality, and decrease your risk of injury.

Since opening our doors 7 years ago, we have trained hundreds of people of all ages with diverse athletic and cultural backgrounds. We will educate, encourage and practice the fundamentals of functional fitness with you in a private setting so you can maximize your fitness efficiency.

Our 5000 sq ft facility is a beautifully designed open space with many different modalities used to challenge every body, complete with full locker rooms and showers. The design allows plenty of space to move about on your own terms and avoid that cooped up feeling.
