9 Low-Impact Cardio Classes That Will Still Make You Feel the Burn

The popular PiYo Live, part of the Beachbody program, is a workout class that is both low-impact and heart-thumping. "PiYo combines traditional Pilates and yoga techniques into a conditioning workout," says Reaver. "Its low-intensity focus combines activities to increase heart rate, and stabilization positions to strengthen and tone muscles. This is a great workout for someone getting back into exercise after some time off." PiYo is available at many different fitness studios across the country, and is also out on DVD if you prefer to do your workouts at home.
