Setup

  1. Stand with your feet slightly wider than shoulder-width apart and toes pointed slightly outward.
  2. Lower into a deep squat until your hips are below your knees, keeping your chest up and back flat.
  3. Place your fingertips or palms on the floor between your feet to establish the starting 'frog' position.

How to do it

  1. Exhale forcefully as you drive through your midfoot to explode upward and slightly forward into the air.
  2. Swing your arms forward and up during the jump to assist with momentum and balance.
  3. Land softly on the balls of your feet, immediately absorbing the impact by sinking back into the deep squat position.
  4. Inhale as you descend and prepare for the next explosive repetition with minimal ground contact time.

Form checklist

  • Keep your chest lifted and gaze forward to prevent the lower back from rounding.
  • Ensure knees track in line with your toes and do not cave inward during takeoff or landing.
  • Land 'quietly' by rolling from the balls of the feet to the heels to protect the joints.
  • Maintain a wide stance throughout the movement to allow for full hip depth.

Pro tips

  • Focus on a rapid transition between landing and the next jump to maximize the stretch-shortening cycle of the muscles.
  • Engage your core throughout the flight phase to maintain a vertical torso and controlled landing.

Make it harder

  • Increase the horizontal distance of each jump to emphasize glute and hamstring power.
  • Hold a light medicine ball at chest height to add external resistance and increase the metabolic demand.
