The forearm is slowly moved towards the body 2 to 3 inches, and held for 5 seconds. The hand should not rotate as the forearm moves.
Part B: The outward rotation isometric exercise is performed with the elbows at 90°, close to the sides. The rubber band is grasped with the hands. The forearms are moved outward 2 to 3 inches and held for 5 seconds. Sets of 15 to 20 exercises, each held for 5 seconds, should be performed daily.
