Isometric Shoulder Flexion

Shoulder · Also called isometric flexion, iso flexion, flexion isometric

Setup

Stand facing a wall with your surgical elbow bent to 90 degrees, your fist against the wall (put a folded towel between fist and wall).

Press your fist gently forward into the wall as if raising your arm — nothing moves. Hold 5 seconds, then relax.

Gentle pressure only — you're turning the muscle on, not testing its strength.
