Equipment

  • Body weight

Setup

  1. Stand tall next to a power rack or sturdy upright, placing one hand on it for balance.
  2. Shift your weight onto your standing leg, keeping a micro-bend in the knee to engage the glute.
  3. Engage your core and fix your gaze forward to maintain a neutral spine.

How to do it

  1. Exhale as you drive your working knee toward your chest as high as possible, keeping the foot flexed.
  2. In a fluid motion, swing the leg back and pull your heel toward your glute (butt kick) while inhaling.
  3. Maintain a steady, rhythmic tempo, ensuring the movement comes from the hip and knee joints rather than the lower back.
  4. Perform the prescribed repetitions on one leg before switching to the other side.

Form checklist

  • Keep the standing leg stable and the foot rooted to the floor.
  • Maintain an upright torso; do not lean forward during the high knee or arch your back during the butt kick.
  • Keep your hips square to the front throughout the entire range of motion.
  • Ensure the movement is controlled and deliberate, avoiding excessive momentum.

Pro tips

  • Focus on 'pulling' the heel toward the glute using the hamstring to maximize muscle activation.
  • Drive the standing foot into the floor to create 'ground force' and better engage the stabilizing glute medius.

Make it harder

  • Remove the hand support to turn the exercise into a high-level balance and core stability challenge.
  • Add ankle weights to increase the resistance for the hip flexors and hamstrings.
