Setup

  1. Stand facing the step with feet hip-width apart and a slight bend in your knees.
  2. Position yourself approximately 6 inches away from the step platform.
  3. Engage your core and keep your chest upright with arms bent at 90 degrees in a ready position.

How to do it

  1. Step up onto the center of the platform with your right foot, followed immediately by your left foot.
  2. Step back down to the floor with your right foot, then your left foot, returning to the starting position.
  3. Maintain a fast, rhythmic 'up-up-down-down' pace, exhaling sharply with each upward step.
  4. Switch your lead leg halfway through the set to ensure balanced development on both sides.

Form checklist

  • Stay on the balls of your feet to maximize speed and minimize impact.
  • Keep a slight bend in the knees throughout the movement to act as shock absorbers.
  • Pump your arms in sync with your legs to maintain momentum and balance.
  • Ensure your entire foot lands on the step to prevent slipping.

Pro tips

  • Focus on 'quiet feet' by landing softly, which forces your muscles to control the deceleration rather than relying on joint impact.
  • Maintain a slight forward lean from the ankles, not the waist, to keep your center of gravity over your base of support.

Make it harder

  • Increase the height of the step to demand greater hip flexion and glute activation.
  • Hold light dumbbells at your sides or wear a weighted vest to increase the cardiovascular and muscular load.
