Burpee Lower into a crouching squat with your hands on the floor. Do a squat thrust by jumping your feet back into a plank position. Do one basic push-up, bending your elbows and then straightening back to a plank. Jump your feet forward to your hands, and come into a squat. Do an explosive jump straight up, getting as much height as you can. Repeat for 40 seconds followed by 20 seconds of rest. Image Source: POPSUGAR Photography
