Mile High Monkey Bar Gym
There are no treadmills, ellipticals, or stairclimbers at Mile High Monkey Bar Gym. Nor are there weight machines or even dumbbells. That's because Mile High Monkey Bar Gym's focus is on functional fitness. Many of its classes incorporate exercises that use your own body weight, supplemented by kettlebells, hanging rings, and other functional equipment. As you progress, Mile High Monkey Bar Gym tracks your progress, and if life interferes and you're unable to come in, its trainers will check in to help you get back on track.
