Setup

  1. Stand with your feet hip-width apart and your arms resting at your sides.
  2. Engage your core and keep your gaze forward with a proud chest.

How to do it

  1. Jump your feet out wide and immediately lower your hips into a squat, keeping your weight in your heels.
  2. Simultaneously swing your arms overhead or out to the sides in a wide arc as you descend into the squat.
  3. Explosively jump back to the starting position, snapping your feet together and bringing your arms back to your sides.
  4. Inhale as you jump out into the squat and exhale as you explosively return to the center.

Form checklist

  • Keep your knees tracking over your toes during the wide squat phase.
  • Maintain an upright torso and avoid rounding your lower back as you descend.
  • Land softly on the balls of your feet before rolling to your heels to absorb impact.
  • Ensure your hips drop toward knee height for maximum glute and quad engagement.

Pro tips

  • Focus on a quick 'rebound' off the floor to maximize the plyometric effect and power output.
  • Keep your core braced throughout the entire movement to stabilize your spine during the rapid transitions.

Make it harder

  • Hold a light medicine ball at chest height to increase the demand on your core and shoulders.
  • Increase the tempo of the repetitions to maximize cardiovascular conditioning and metabolic burn.
