Stand with your feet shoulder-width apart and your arms at your sides. Bend your knees and sit your hips back to squat slightly. Then quickly swing your arms up overhead and explode upward by pressing your feet into the floor. Your feet should leave the floor as you jump. Land on the balls of your feet with soft knees and then jump explosively again. Do 10 to 12 repetitions.
