I'm a member of 24 Hour Fitness here in Northgate. I've been trying to go once a day. What I love at 24 Hour Fitness is Zumba, Body Pump, and the elliptical. Body Pump is helping me build muscle and lose weight. You use a bar with weights as you do squats, lunges, and lifts. The music makes it fun to do the repetitive motions. I've been told it is 800 repetitions per class.
