"POUND is a full-body cardio jam session, combining light resistance with constant simulated drumming. The workout fuses cardio, Pilates, isometric movements, plyometrics and Isometric poses into a 45-minute series. Burn between 400 and 900+ calories per hour, strengthen and sculpt infrequently used muscles, and drum your way to a leaner, slimmer physique – all while rocking out to your favorite music!
Through continual upper body motion using our lightly weighted drumsticks, called Ripstix™, you’ll turn into a calorie-torching drummer, POUNDing off pounds as each song flies by. Rock, rap, dubstep, pop and old school music fuse to create the POUNDtrack series, which is hand-selected by music enthusiasts, drummers and POUND founders Kirsten Potenza and Cristina Peerenboom."
