Range of motion arc with half pound wrist weights. At grade 3+ the man will be able to move his arms through full range of motion against gravity and will be able to tolerate gradual increases in resistance. He should be able to tolerate sliding rings across the range of motion arc with light resistance, provided by the half pound wrist weights. Exercises using a wall mounted finger ladder or table top sanding are designed for people who have less than grade 3 shoulder strength, so these activities will not be challenging enough for the man. Working against gravity for prolonged periods of time is difficult for people with grade 3+ arm strength, so the man will probably not be able to sustain shoulder flexion against gravity to work overhead on the nut and bolt board.
