Although the ankle is the most injured body part of an athlete, very little is ever done to strengthen
the stabilizing muscles that prevent rolling in and out. Golfers are no exception in neglecting ankle
strengthening. They seldom sprain their ankle swinging the golf club, but strength of ankle muscles is
very significant to maintaining positions that establish balance, and create a powerful and efficient
golf swing

The stronger and better trained your ankles are:

The more power you can deliver at impact
The better your ability to maintain proper spine angles
You can more effectively resist compensatory moves in the swing
Perform this as an exercise and hitting drill. You will gain strength, improve footwork, establish better
golf balance and increase swing power as you move from the backswing, into your forward swing, to impact
and to the finish position.
