You don’t have to be in a band to take advantage of this fitness trend, which lets you release your inner rock star. Pound, a workout created by California-based drummers Kirsten Potenza and Cristina Peerenboom, involves hitting the ground over 1,000 times during cardio workouts with lightly weighted drumsticks called Ripstix. The session mixes conditioning and interval training, and is available at studios and gyms nationwide, including Crunch. Drums Alive is another drum-based workout; it incorporates aerobic dancing and jamming on exercise balls.
