Setup
- Stand perpendicular to a wall or door frame with your target arm closest to the wall.
- Bend your elbow to 90 degrees and tuck it firmly against your side.
- Place your palm and forearm flat against the corner of the wall or door frame.
How to do it
- Press your palm into the wall as if rotating your arm inward toward your stomach, while keeping your elbow pinned to your side.
- Exhale as you ramp up the tension and maintain a steady, forceful contraction for the prescribed duration.
- Inhale and slowly release the pressure before repeating the set or switching sides.
Form checklist
- Keep your elbow glued to your ribs throughout the entire hold.
- Maintain a tall, neutral spine and avoid leaning your body weight into the wall to create force.
- Keep your shoulders level and depressed; do not let the shoulder shrug toward your ear.
- Ensure your wrist remains straight and neutral, not bent.
Pro tips
- Place a small rolled-up towel between your elbow and your side to ensure the arm stays tucked and the rotator cuff is properly isolated.
- Focus on the mind-muscle connection by visualizing the muscle deep under your shoulder blade and your chest doing the work.
Make it harder
- Increase the intensity of the push to a maximal voluntary contraction, pushing as hard as possible against the wall.
- Perform the isometric hold at slightly different angles by rotating your body slightly toward or away from the wall.
