Isometric Slightly Pistol Squat

  • Intermediate

Equipment

Setup

  1. Stand tall with feet hip-width apart, then shift your weight entirely onto your target leg.
  2. Lift the non-working leg slightly off the floor in front of you, keeping it straight or slightly bent.
  3. Extend your arms forward at shoulder height to act as a counterbalance.

How to do it

  1. Inhale and slowly lower your hips back and down into a partial squat, roughly 30 to 45 degrees of knee flexion.
  2. Hold this static position for the prescribed duration while maintaining a braced core.
  3. Breathe rhythmically through the nose, avoiding holding your breath during the isometric hold.
  4. Exhale and drive through the mid-foot to return to a standing position once the time is up.

Form checklist

  • Keep the standing knee tracking in line with your second toe; do not let it cave inward.
  • Maintain a neutral spine and keep your chest lifted throughout the hold.
  • Ensure the heel of the standing foot remains firmly planted on the ground.
  • Keep the non-working leg elevated and clear of the floor at all times.

Pro tips

  • Root your foot into the ground by spreading your toes and gripping the floor to maximize stability and neural drive.
  • Actively squeeze the glute of the standing leg to stabilize the pelvis and prevent the hip from shifting outward.

Make it harder

  • Increase the depth of the squat toward a 90-degree angle to significantly increase the demand on the quadriceps.
  • Close your eyes during the hold to remove visual feedback and force the stabilizer muscles to work harder.
