Full Squat Mobility

  • Beginner
  • Compound
  • Rep-based
  • Lower legs
  • Upper legs

This mobility drill improves functional range of motion in the hips, knees, and ankles while promoting lower body flexibility and joint health. It is highly effective for restoring natural squat mechanics and relieving tension in the lower back and adductors.

Equipment

  • Body weight

Setup

  1. Stand with your feet slightly wider than shoulder-width apart.
  2. Point your toes slightly outward (about 15-30 degrees) to allow for better hip tracking.
  3. Distribute your weight evenly across your entire foot, focusing on the tripod of the heel, big toe, and pinky toe.

How to do it

  1. Inhale and slowly lower your hips toward the floor, keeping your chest upright and your heels firmly planted.
  2. Descend as deep as your mobility allows, ideally until your hamstrings touch your calves.
  3. Hold the bottom position for the prescribed duration, breathing deeply into your belly to relax the pelvic floor and hips.
  4. Exhale and drive through your mid-foot to return to a standing position.

Form checklist

  • Keep your heels glued to the floor at all times.
  • Ensure your knees track in line with your toes, preventing them from caving inward.
  • Maintain a relatively upright torso and avoid excessive rounding of the lower back.
  • Keep your gaze forward to help maintain balance and posture.

Pro tips

  • Use your elbows to gently press your knees outward to increase the stretch in your adductors.
  • Gently shift your weight from side to side while in the deep squat to target specific ankle restrictions.
  • Focus on 'prying' the hips open by actively engaging your glutes at the bottom of the hold.

Make it harder

  • Add thoracic rotations by reaching one arm toward the ceiling while the other stays anchored to the floor.
  • Perform the hold while holding a light weight in front of your chest to act as a counterbalance for a deeper, more upright stretch.
