I haven't belonged to a 24 Hour Fitness for several years but I LOVED Body Pump. (Choreographed weight lifting to peppy music).

Come to think of it, that's why I left. They discontinued Body Pump and replaced it with Rebock Rep, dull, dull, dull.

My current gym had Body Pump for a few years, then replaced it with Group Power, but they're the same thing really. Fun class, vigourous workout, and the hour flies. Probably 24 has dumped Rebock Rep by now and gone back to Body Pump or something similar. It's a hoot.

Only problem: Wear ear plugs or your hearing will be damaged.
