Single Leg Heel Touch Squat

  • Intermediate
  • Compound
  • Rep-based

This unilateral squat variation builds exceptional lower body strength, balance, and ankle stability by isolating one leg through a deep range of motion. It specifically targets the quadriceps and glutes while demanding high levels of core engagement for stabilization.

Setup

  1. Stand tall on one leg with your foot firmly planted and the other leg extended slightly forward.
  2. Engage your core and find a focal point straight ahead to maintain balance.
  3. Extend your arms in front of your chest to act as a counterbalance.

How to do it

  1. Inhale as you slowly lower your hips by bending at the knee and hip of the standing leg, keeping your weight centered.
  2. Descend with control until the heel of your non-working leg lightly grazes the floor in front of you.
  3. Exhale and drive through the mid-foot of the standing leg to return to the starting position.
  4. Maintain a controlled tempo, taking roughly 3 seconds for the descent and 1 second for the ascent.

Form checklist

  • Keep the knee of the standing leg tracking in line with your toes, avoiding internal collapse.
  • Maintain a proud chest and neutral spine throughout the entire movement.
  • Ensure the heel of the standing leg stays glued to the floor at all times.
  • Only lightly touch the floor with the non-working heel; do not shift any weight onto it.

Pro tips

  • Focus on 'grabbing' the floor with your toes to increase foot stability and arch support.
  • Imagine sitting back into a chair rather than just pushing the knee forward to maximize glute recruitment and protect the knee joint.

Make it harder

  • Increase the range of motion by standing on a small platform or aerobic step.
  • Hold a light weight at chest height to increase the demand on the core and lower body.
