Equipment

  • Body weight

Setup

  1. Stand perpendicular to a wall with your feet hip-width apart for a stable base.
  2. Extend the arm closest to the wall and place your palm and forearm flat against the surface.
  3. Position your hand so your arm is angled approximately 45 degrees upward from the horizontal shoulder line.

How to do it

  1. Slowly rotate your torso and hips away from the wall while keeping your arm and shoulder fixed in place.
  2. Exhale as you lean your weight slightly forward to deepen the stretch in the upper chest and front of the shoulder.
  3. Hold the position for 30 seconds, maintaining steady, deep breaths to allow the muscle to relax.
  4. Slowly rotate back to the starting position and repeat the stretch on the opposite arm.

Form checklist

  • Keep your shoulder blade pulled back and down, away from your ear.
  • Maintain a slight, soft bend in the elbow to avoid placing stress on the joint.
  • Keep your chest upright and avoid hunching or rounding your upper back.
  • Ensure your palm and inner elbow stay in contact with the wall throughout the stretch.

Pro tips

  • Focus on rotating from your hips and core to create leverage rather than just pulling on the shoulder joint.
  • Experiment with slight variations in the hand angle to find the specific point of maximum tension in your pectoral fibers.

Make it harder

  • Incorporate a PNF technique by gently pressing your hand into the wall for 5 seconds, then relaxing and rotating further into a deeper stretch.
  • Step forward with the leg on the same side as the stretching arm to increase the leverage and intensity of the stretch.
