Setup
- Stand perpendicular to a wall or sturdy door frame with your feet in a staggered stance.
- Place your forearm and palm flat against the wall with your elbow bent at a 90-degree angle.
- Position your elbow so it is level with or slightly higher than your shoulder.
How to do it
- Slowly rotate your torso and hips away from the wall while keeping your arm and shoulder fixed against the surface.
- Exhale as you lean your chest forward and turn, feeling a deep stretch across the front of your chest and shoulder.
- Hold the stretch for 20-30 seconds while maintaining deep, diaphragmatic breathing.
- Slowly return to the starting position and repeat the process on the opposite side.
Form checklist
- Keep your shoulder blade pulled down and back to avoid shrugging during the stretch.
- Maintain a tall, upright spine without leaning into the wall or arching your lower back.
- Ensure the elbow stays in contact with the wall throughout the entire duration.
- Stop the rotation once you feel a strong but comfortable tension; avoid sharp pain.
Pro tips
- Vary the height of your elbow on the wall to target different sections of the pectoral muscles (higher for lower pecs, lower for upper pecs).
- Focus on the mind-muscle connection by imagining your chest 'opening up' rather than just pulling your arm back.
Make it harder
- Perform the stretch with a straight arm to increase the leverage and intensity on the pectoral insertion.
- Apply PNF stretching by pushing your arm into the wall for 5 seconds, then relaxing and rotating further into a deeper stretch.
