Setup

  1. Set a cable pulley to the lowest position and attach a D-handle.
  2. Place a sturdy box or step approximately 12-18 inches in front of the cable machine.
  3. Stand facing the box and hold the handle in the hand on the same side as your working leg.
  4. Place your working foot firmly on the center of the step, ensuring the entire foot is supported.

How to do it

  1. Lean your torso slightly forward and drive through the heel of the elevated foot to stand up onto the box.
  2. Exhale as you ascend, keeping the trailing leg passive to ensure the working leg does all the lifting.
  3. At the top of the movement, stand tall and squeeze your glutes before beginning a controlled descent.
  4. Inhale as you slowly lower yourself back to the starting position over a 3-second tempo, barely touching the floor with your trailing foot.

Form checklist

  • Keep the working knee aligned with your toes, avoiding any inward collapse.
  • Maintain a neutral spine and avoid rounding your shoulders toward the cable.
  • Ensure you are not 'jumping' or pushing off the ground with your bottom foot.
  • Keep the weight centered over the middle of the working foot throughout the rep.

Pro tips

  • To maximize glute recruitment, keep your shin as vertical as possible and hinge slightly at the hips during the ascent.
  • Flex the toes of your trailing foot upward to prevent yourself from using them to push off the floor.

Make it harder

  • Increase the height of the step to deepen the hip flexion and increase the range of motion.
  • Add a 2-second pause at the bottom of each rep to eliminate all elastic momentum.
