Muscles worked

  • Hamstrings

Equipment

  • Body weight

Setup

  1. Lie on your side on a flat surface with your legs stacked and extended.
  2. Rest your head on your bottom arm or a small pillow for neck support.
  3. Bend your bottom knee slightly toward your chest to create a stable base of support.

How to do it

  1. Reach back with your top hand and grasp the ankle or the top of the foot of your top leg.
  2. Exhale as you gently pull your heel toward your glutes until you feel a comfortable stretch in the front of your thigh.
  3. Hold the position for 20-30 seconds while maintaining deep, rhythmic breathing.
  4. Slowly release the foot, roll over, and repeat the process on the opposite side.

Form checklist

  • Keep your knees close together; do not let the top knee flare up toward the ceiling.
  • Maintain a neutral spine and avoid arching your lower back as you pull the leg back.
  • Keep your hips stacked vertically to prevent rotating your torso backward.
  • Grip the ankle rather than the toes to avoid unnecessary strain on the ankle joint.

Pro tips

  • Squeeze the glute of the leg being stretched to drive the hip forward, which deepens the stretch in the rectus femoris.
  • Focus on a 'posterior pelvic tilt' (tucking your tailbone) to maximize the tension on the hip flexors.

Make it harder

  • Transition to a prone (face-down) position to increase the hip extension demand.
  • Actively push your foot into your hand for 5 seconds (isometric contraction), then relax and pull deeper into the stretch.
