Straps that wrap around your body have been around a long time. Ben Hogan use to use belts around his arms and legs to train his arms and legs to work correctly. The Swing Link wraps around your torso with separate straps for your arms. This teaches you how to get your arms and torso in unison. This is a great aid for golfers who use too much arm movement independent of the body. Again the key here is that it meets my requirement of you use your own club and you can hit balls with it.
