Easy to use: The forearm pivot point aligns the hand and forearm, preventing wrist bending and keeping the hand on a single surface for consistent stroke across breaststroke, butterfly, and backstroke. Full set included: Each package comes with a pair of elbow correctors, providing everything you need to correct form and start improving immediately. Swimming training aid: This arch-shaped forearm corrector supports more efficient stroke mechanics, helping you reduce drag and maintain a steady, powerful pull. How it works: The forearm pivot point connects the forearm and hand into one surface by stopping wrist flexion, promoting a streamlined line from arm to hand. Use scenarios: - In training sessions, use during breaststroke drills to improve hand entry, catch, and propulsion. - During butterfly sets, wear the corrector to maintain a straight forearm and stable wrist. - In backstroke practice, use it to reinforce a flat, connected forearm-hand surface for a stronger pull. - At home or dryland training, rehearse the correct position to reinforce muscle memory. Notes: Designed to improve hand positioning and stroke efficiency with included elbow correctors for a complete setup. Material and size specifications are not provided.
