A training strap for improving a golfer's golf stroke is provided. The training strap includes a shoulder strap that attaches around the lead shoulder of the golfer with the opposite end attaching around the golfer's thumb on the same lead side of the body. Preferably, the training strap includes a strap length adjuster allowing the training strap to be fitted to the proper length. The golfer practices the stroke with the criterion being to keep the training strap taut. If the training strap stays taut, the user will develop a very fundamentally sound, repeatable stroke. When this is done the golfer is successfully utilizing the radius from the lead shoulder to hands to bottom out at the correct spot, thereby creating a good chipping, pitching or putting stroke.
