This exercise will not only teach you to load your weight into your back side at the top of your swing, but it will also help you improve your balance and build muscular endurance for better golf.
Set up in your golf posture without a golf club and simply hold your arms out as if you were holding a ball.
Make a backswing and stop at the top.
Lift your front foot off the ground so that all your weight is on the back side. Keep your head steady and maintain your balance.
Return to the start position and repeat exercise.
Do 8 to 10 repetitions.
