An overnight sensation, the Smart Ball was on the market a few years before Justin Rose saw it on tour. Suddenly it gained a huge following. It is simply an inflatable ball that, when used as directed, gives the feeling that the body and arms move as one unit during the swing.
To use, simply inflate it, hook it onto the adjustable loop and gently squeeze it between your forearms. Start with a half swing to experience a connected feeling. You will be surprised at how far apart your arms move apart during the swing.
The device can also be used on pitches and chips. Best of all, it weighs next to nothing and folds up for easy storage in your golf bag.
