Burpees are infamous in the fitness world, thanks to their intense full-body impact. They combine a squat, push-up, and jump into one powerful movement. To do a burpee, start standing, then squat down and place your hands on the ground. Kick your feet back to a push-up position and perform a push-up. Quickly bring your feet back under you, then explode upwards into a jump. Land softly and immediately begin the next rep.
