Muscles worked

Primary

  • Lats
  • Rotator cuff

Secondary

  • Abs
  • Serratus anterior

Equipment

  • Body weight

Setup

  1. Stand perpendicular to a wall or door frame with your target arm closest to the wall.
  2. Bend your elbow to 90 degrees and tuck it firmly against your side.
  3. Place your palm and forearm flat against the corner of the wall or door frame.

How to do it

  1. Press your palm into the wall as if rotating your arm inward toward your stomach, while keeping your elbow pinned to your side.
  2. Exhale as you ramp up the tension and maintain a steady, forceful contraction for the prescribed duration.
  3. 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.
