They require you to fill out an application and complete a brief interview—just to make sure you're ready for pain—but after that, your strength coach will help you turn it all around. Basic membership is $100 for 45–60 mins, 3–5 times per week.
Powerhouse Gym programs include O2 cycling, cross training and personal training.
Adventure in Movement (AIM) Boot Camp is a men's only program where you can make fast buddies as you flip tires, hurl sand sacks, do speed and agility drills and occasionally jump into multi-sport territory with rope challenges and rock climbing. AIM hands you the tools you need to get in peak fitness.

And after you're successfully singeing calories on your own, join one of the dozens of team sports that the club has organized. $150 for 5 weeks
