The hot potato squat may sound like a kid's recess activity, but don't be fooled -- it's also a cutting-edge fat-loss exercise that will get your heart pumping and your muscles burning in almost no time, says BJ Gaddour, C.S.C.S., owner of StreamFit.com. It starts with one of the most effective exercises invented: the squat. When done correctly, a squat trains a lot of muscles, particularly big ones like your quadriceps, hamstrings and glutes. In fact, it burns more calories per rep than almost any other exercise. (When it's time to take your shirt off, your chest and arms will be ready with this routine that's designed to pack on muscle. Try The Summer Beach Body Workout.)
But why stop there? Gaddour throws an airborne dumbbell into the mix to make this classic move even more challenging and beneficial. "Holding the weight on just one side of your body increases the demand placed on your core to keep your body stable," he says. "As the weight changes from side to side, your core muscles are worked from every angle."
