Transform your golf game with the Impact Ball - a revolutionary and PATENTED training aid designed to perfect your swing mechanics. BACK AND BETTER THAN EVER! Since 2005, The Impact Ball has been the favorite of PGA coaching professionals, Tour professionals, and elite student athletes for training perfect posture through all phases of the golf swing. The Impact Ball helps eliminate common swing errors like flying elbows, scooping, and improper wrist control by maintaining the crucial elbow-to-wrist triangle throughout your swing. The Impact Ball is also ideal for training putting, by locking your shoulders and wrists to encourage a pendulum shoulder-swing putting motion. The dual-color sections of The Impact Ball helps visualize proper body rotation through your swing. The New & Improved Impact Ball features a sturdy lanyard design for convenient practice sessions, upgraded premium materials for superior comfort, and improved construction for lasting durability. Whether you're working on your driver swing or perfecting your short game, this versatile training tool helps develop muscle memory for consistent, pure contact. The Impact Ball's proven design keeps your arms in optimal position from backswing to follow-through, helping golfers of all skill levels achieve better accuracy and reduce unwanted ball spin that causes slicing and hooking. Available in three sizes to accommodate different player heights: Small (under 5'4"), Medium (5'0" to 5'10"), and Large (over 5'11").
