Equipment

  • Body weight

Setup

  1. Stand with your feet slightly wider than shoulder-width apart, toes pointed slightly outward.
  2. Engage your core and maintain an upright posture with your arms relaxed at your sides.
  3. Take a deep, expansive breath into your chest to prepare for the explosive movement.

How to do it

  1. Inhale deeply as you lower into a squat, keeping your weight centered and your chest proud.
  2. Explosively jump upward, exhaling forcefully while swinging your arms out to the sides and up to shoulder height in a 'flapping' motion.
  3. Land softly on the balls of your feet, immediately absorbing the impact by transitioning back into the next squat.
  4. Maintain a rhythmic tempo, synchronizing the arm movement and deep breathing with every repetition.

Form checklist

  • Ensure knees track over the toes and do not cave inward during the squat or landing.
  • Keep the spine neutral and avoid rounding the lower back at the bottom of the movement.
  • Land quietly to ensure your muscles, not your joints, are absorbing the impact.
  • Keep the core braced throughout to stabilize the torso during the flight phase.

Pro tips

  • Focus on 'opening' the chest at the peak of the jump to maximize pectoral and deltoid activation.
  • Use the downward 'flap' of the arms to help drive the body upward, creating more vertical power and momentum.
  • Emphasize the deep inhale during the eccentric phase to expand the ribcage and engage the serratus and pectorals.

Make it harder

  • Increase the speed of the repetitions to minimize ground contact time and boost cardiovascular intensity.
  • Add a pause at the bottom of the squat to remove momentum before the explosive jump.
