JumpLife
There's a lot of talk of "healthy partying, long-lasting energy, and calorie scorching" on JumpLife's website, but all I'm seein' is the opportunity to jump on a trampoline for 45 minutes and not have someone tell me that I'm "too old to double-bounce a 5 year old." The only thing remotely stress inducing about this workout is the amount of sports bras you'll have to wear.
