Setup
- Stand perpendicular to a wall or sturdy vertical support with your feet hip-width apart.
- Extend the arm closest to the support behind you and place your palm flat against the surface at shoulder height.
- Position your thumb pointing upward or slightly backward to optimize the shoulder rotation.
How to do it
- Slowly rotate your entire torso away from the wall while keeping your hand and arm fixed in place.
- Exhale as you turn, moving until you feel a comfortable tension across your chest and front shoulder.
- Hold the stretch for 20-30 seconds while taking deep, controlled breaths.
- Slowly rotate back to the center to release the tension and repeat on the opposite side.
Form checklist
- Keep your shoulder blade retracted and depressed, avoiding the 'shrug' toward your ear.
- Maintain a very slight micro-bend in the elbow to protect the joint.
- Keep your torso upright and core engaged to prevent arching your lower back.
- Ensure your feet and hips turn with your torso to avoid twisting at the spine.
Pro tips
- Vary the height of your hand on the wall; a higher hand position targets the lower pectorals, while a lower hand position emphasizes the upper pectorals and biceps.
- To deepen the bicep stretch, focus on fully extending the elbow and pressing the base of your palm into the support.
Make it harder
- Lean your body weight slightly forward while rotated to increase the leverage on the anterior deltoid.
- Perform the stretch with your arm bent at a 90-degree angle (cactus arm) against the wall to focus more intensely on the pec minor.
