Stand with your feet shoulder width apart. Squat down and place your hands palms down on the floor in front of your feet. Lean forward, so your weight is on your hands, at the same time jumping your legs out behind you until they are fully extended. Your body should form a straight line with your arms fully extended in a high plank position. Lower down from this position until your chest and body touch the floor. Push through your arms and feet simultaneously to return to the high plank position. Then jump your feet forward to just behind your hands. In one explosive movement, push through your feet extending your knees and hips and jump up as high as you can and extending your arms overhead. Repeat for the required number of reps (or time).
