Be it jumping in a pool, punching a heavy bag, or stretching into your favorite yoga pose, there’s plenty of spaces to do just that in Denver. But choosing the right gym is no easy task. Luckily, several gyms around Denver offer free trial passes, so you can give them a try before you sign your gut away.
