Setup

  1. Stand on top of a stable box or platform (12-24 inches high) with feet hip-width apart.
  2. Position your toes near the front edge of the box.
  3. Maintain an upright posture with your core engaged and arms relaxed at your sides.

How to do it

  1. Step one foot off the box and drop straight down toward the floor without jumping upward.
  2. Land on the balls of both feet simultaneously, immediately transitioning into a maximal vertical jump.
  3. Exhale sharply during the jump phase and swing your arms upward to generate momentum.
  4. Minimize the time your feet are in contact with the ground to maximize reactive power.

Form checklist

  • Land with 'soft' feet to absorb impact, but stay stiff enough to bounce back up immediately.
  • Keep your knees tracked over your toes; do not let them cave inward upon landing.
  • Maintain a neutral spine and avoid excessive forward lean during the transition.
  • Ensure the landing from the final jump is controlled with hips pushed back and knees slightly bent.

Pro tips

  • Focus on 'stiffness' in the ankles and knees to transfer energy efficiently from the drop into the jump.
  • Imagine the floor is hot lava—the goal is to spend as little time on the ground as possible while still reaching maximum height.

Make it harder

  • Increase the height of the starting box to increase the eccentric load on the muscles.
  • Perform a 'Depth Jump to Box' by jumping onto a second, higher box immediately after the floor contact.
