Setup
- Stand perpendicular to a wall with your feet hip-width apart for a stable base.
- Extend the arm closest to the wall and place your palm and forearm flat against the surface.
- Position your hand so your arm is angled approximately 45 degrees upward from the horizontal shoulder line.
How to do it
- Slowly rotate your torso and hips away from the wall while keeping your arm and shoulder fixed in place.
- Exhale as you lean your weight slightly forward to deepen the stretch in the upper chest and front of the shoulder.
- Hold the position for 30 seconds, maintaining steady, deep breaths to allow the muscle to relax.
- 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.
