Equipment

  • Body weight

Setup

  1. Place a sturdy box or platform approximately 1-2 feet in front of you.
  2. Kneel on a soft mat with your shins flat on the floor and your hips resting on your heels.
  3. Maintain an upright torso with your arms at your sides, ready to swing for momentum.

How to do it

  1. Explosively drive your hips forward and swing your arms upward while snapping your feet underneath you into a deep squat position.
  2. Immediately transition from the floor into a vertical jump, exhaling forcefully during the ascent.
  3. Land softly on top of the box in a partial squat, absorbing the impact through your midfoot and heels.
  4. Step down carefully one foot at a time to reset the starting kneeling position.

Form checklist

  • Land quietly on the box with knees tracking in line with your toes.
  • Ensure full hip extension during the initial 'pop' from the kneeling position.
  • Keep your core braced throughout the transition to stabilize the spine.
  • Avoid rounding your lower back when landing on the box.

Pro tips

  • Focus on the 'snap' of the hips; the faster the transition from kneeling to feet, the more power you will generate for the jump.
  • Drive your knees toward your chest as you leave the floor to maximize clearance height.

Make it harder

  • Increase the height of the box to demand greater peak power output.
  • Hold a light medicine ball at chest height to eliminate the momentum from the arm swing.
