Setup

  1. Stand sideways next to a step or low platform with your feet hip-width apart.
  2. Keep your chest upright, core engaged, and hands held in a 'guard' position near your chin.
  3. Position yourself so the foot closest to the step is ready to lead the lateral movement.

How to do it

  1. Step laterally onto the platform with your inside foot, driving through the heel to lift your body upward.
  2. As you rise, rotate your torso toward the step and punch the opposite arm diagonally upward toward the sky, pivoting on the ball of your trailing foot.
  3. Exhale sharply during the punch and peak contraction, then inhale as you step back down to the starting position.
  4. Return to the guard stance and repeat the movement on the opposite side by switching your orientation to the step.

Form checklist

  • Keep your core braced throughout the movement to stabilize the spine during rotation.
  • Ensure the knee of the stepping leg tracks directly over the toes, avoiding any inward collapse.
  • Pivot fully on the back foot to allow the hips to rotate freely with the punch.
  • Maintain a tall, upright posture; do not lean forward or round your shoulders as you step.

Pro tips

  • Focus on the kinetic chain: generate power from the floor, drive it through your hips, and finish with an explosive punch.
  • Squeeze the glute of the standing leg at the top of the step to maximize stability and rotational force.

Make it harder

  • Increase the height of the step to further challenge the quadriceps and glutes.
  • Hold light dumbbells to add resistance to the punch and increase the demand on the deltoids and triceps.
