Balance is a critically important element of an effective and powerful golf swing. Here are some drills to help you to achieve better balance in your swing:
Foot lift: In golf posture, lift your left foot off the floor and balance for as long as possible. Then do the opposite side. To intensify dramatically, close your eyes. PGA Tour average is 45 seconds with eyes closed.
Stability ball balance: If you have access to a stability ball, sit on the ball and then lift feet off the ground.
One-foot golf swings: While standing on right foot, hit shots with wedge. Then do it on left foot.
