Begin with a two boxes of an appropriate height in front of you. Stand with your feet shoulder width apart. Perform a short squat in preparation for jumping, swinging your arms behind you.
Rebound out of this position, extending through the hips, knees, and ankles to jump as high as possible. Swing your arms forward and up.
Land on the first box with the knees bent, absorbing the impact through the legs.
Immediately swing your arms and jump again onto the second box.
Absorbing the impact through the legs jump from the second box back to the floor. Repeat the exercise according to the training plan.
