I live in Orange County, CA - ground zero of Turbo Jam creator Chalene and a member of 24Hour Fitness. She teaches a class down the street but it's during work hours so I can't attend.

I've seen the TJ videos but have never done it. But 24 does have a gym version called TurboKickBoxing. From what I heard the gym version is a more intense version simply because we have a live instructor and we feed off each other's energy. I've been participating in TKB for the last couple years. It aided my weight loss from 220 to 180 lbs.

It's a really great workout if you learn the fundamentals which are the 11 moves - i.e. the 4 punches, the kicks, roundhouse, zigzags, turbo twist, etc. It's important you keep your core muscles tight because that is your powerhouse.

I love TurboKick because you not only get a great cardio workout but also tone your core muscles and your entire body - if you use correct form.
