The Swing Extender designed by Tommy Brannen, limits the amount the player can bend their arm to 90 degrees in the backswing. By doing so, The Swing Extender creates a straighter left arm (for right handed players), provides you with an increase in shoulder turn, more width, power and control.
The Swing Extender Training Aid can be worn by both right and left handed golfers of all ages, sizes and skill levels. All you must do is secure the Swing Extender to the bicep of your trail arm inside the strap loop and swing. It is super easy to take on and off, lightweight and most importantly... effective!
