Setup

  1. Stand to the left side of the step platform with your feet hip-width apart.
  2. Place your right foot firmly in the center of the step.
  3. Engage your core and place your hands behind your head with elbows flared out.
  4. Keep a slight bend in your knees and your chest lifted.

How to do it

  1. Push off the step and the floor simultaneously to jump laterally over the platform, switching feet in mid-air.
  2. Land softly with your left foot on the step and your right foot on the floor in a wide stance.
  3. Immediately perform a controlled side bend, bringing your left elbow toward your left hip to crunch the obliques.
  4. Exhale sharply during the jump and side bend, then inhale as you prepare to jump back to the starting side.

Form checklist

  • Land softly on the balls of your feet to absorb impact through the calves and quads.
  • Keep your torso facing forward; avoid rotating your shoulders during the side bend.
  • Ensure the knee of the leg on the step stays aligned with your toes, not caving inward.
  • Maintain a neutral spine and avoid hunching forward during the lateral transition.

Pro tips

  • Focus on 'shortening' the distance between your ribcage and hip bone during the side bend for maximum oblique activation.
  • Minimize your ground contact time to increase the plyometric demand on your calves and glutes.
  • Keep your elbows back to ensure the side bend stays in the frontal plane, maximizing the stretch on the opposite side.

Make it harder

  • Increase the height of the step platform to demand more vertical power and hip stability.
  • Hold a light medicine ball or weight plate overhead to increase the lever arm and core resistance.
