  "description": "A targeted wrist exercise that trains radial deviation — tilting the hand toward the thumb side. Sitting with the forearm supported and the thumb pointing up, you hold a light weight (or a hammer gripped near its head) and raise the hand upward through a small arc, then lower it slowly. It isolates the radial wrist muscles that are rarely trained directly, building strength and control at a joint most people only ever move incidentally.",
