A light and portable way to help you develop your ball striking by helping you train your arms and body to move or sequence properly through the golf swing and help reduce the “chicken wing”.
It is an inflatable, flocked ball – a small beach ball, connected to a lanyard that can be adjusted for most heights and builds.   This swing ball training aid provides you with positive feedback so that you can reinforce your learning for the longterm.  Use inflated between the arms or flat (uninflated) under the armpit.
