“One of my all-time favorite total-body moves, this simple but effective exercise works your legs, core, and upper body," says Samantha Clayton, a former Olympic athlete and personal trainer. "You can do them with no equipment, or you can make them more core intensive by using a BOSU [as shown] or stability ball."
How to do it: Squat down and place your hands on the BOSU (or flat on the floor), and jump your feet back so that you land in a pushup position. Lower your chest to the ground, press back up to complete the pushup, and then jump your feet back in to a squat position. Hold onto the BOSU as you explosively jump up in the air, pressing the BOSU overhead (or just reach your arms up). That's one rep. Try to do 3 sets of 15 reps, or 3 sets of as many reps as possible in 45 seconds.
