Start in a standing position with your feet shoulder-width apart. Lower your body into a squat position, placing your hands on the ground in front of you. Kick your feet back, landing in a push-up position. Perform a push-up, lowering your chest to the ground and then pushing back up. Jump your feet forward, landing in a squat position. Jump up explosively, reaching your arms overhead. Land softly and immediately lower back into the squat position to begin the next repetition.
