  "description": "A targeted wrist exercise that trains the muscles moving the hand toward the little-finger side (ulnar deviation). With the forearm supported and thumb pointing up, you hold a light weight and slowly tilt the hand downward toward the floor, then control it back up. It isolates a small, rarely-trained motion that stabilizes the wrist during gripping, carrying, and tool use.",
