THEMARS Golf Swing Trainer Ball, Size Medium, Forearm Connector for Putting Chipping and Full Swing, PU with Lanyard

THEMARS Golf Swing Trainer Ball is a contoured forearm connector that locks elbows and wrists together to train a consistent, connected swing for putting, chipping, and full shots.

Designed for golfers who want immediate, tactile feedback, this compact training aid fits between the forearms to promote a unified arm motion and correct common faults like wrist flip and early release. Made from soft, durable PU with ergonomic concave dents, the ball stays put through drills and full swings. It’s available in three sizes with an adjustable lanyard so you can practice comfortably anywhere — at the range, on the practice green, or in your living room.

How does this trainer help eliminate wrist flipping and the "chicken wing"?

The THEMARS connector enforces the elbow-wrist triangle so you maintain a stable wrist angle through impact. By physically linking both forearms, the trainer prevents the lead arm from collapsing and discourages scooping or flipping the clubhead.

• Concave grooves cradle forearms to keep alignment consistent during the swing.
• Tactile resistance encourages a forward weight shift at impact.
• Immediate feedback alerts you when the lead elbow collapses or wrists break down.

Can I use the ball for putting, chipping, and full-swing practice?

Yes — this is a multi-use training aid. Use it for short game drills to stabilize the lower body and maintain a pendulum-style putting stroke, then switch to chips and full swings to reinforce connection and transfer of energy through impact.

• Putting: reduces wrist movement and promotes a smooth back-and-forth motion.
• Chipping: keeps hands and arms unified for cleaner contact and consistent contact point.
• Full swings: supports a compact, connected motion from takeaway to follow-through.

Which size should I choose and how does the lanyard work?

The trainer comes in S, M, and L so you can match the ball to your arm span and build for a secure fit. The included adjustable neck lanyard keeps the ball positioned between the forearms, preventing drops during aggressive practice while allowing quick removal between shots.

• Size guide helps you select S, M, or L for a snug, non-slip fit.
• PU construction offers soft contact yet holds shape under repeated use.
• Lanyard adjusts easily to keep the ball centered without constraining motion.

What immediate benefits will I notice during practice?

Most users report clearer feel for impact position and fewer wrist-related errors within a few practice sessions. The trainer accelerates muscle memory for connected arm motion and a more consistent strike pattern across all shot types.

• Improved impact feel and repeatability in short practice blocks.
• Reduced hand action and more reliable weight transfer through the ball.
• Portable design lets you drill the same motion on the range or greenside.

Who is this for: The THEMARS Golf Swing Trainer Ball is suitable for beginners who need basic connection drills, weekend players striving to remove wrist breakdown, and advanced golfers working on marginal swing refinements. Its multi-size option and universal usability make it a useful coaching aid for juniors, adults, and instructors looking to demonstrate correct forearm and wrist relationship without relying solely on verbal cues.
