A Solid Foundation
If the club bottoms out too far behind the ball, pay attention to your right foot. Make sure that it isn’t rolling back with your backswing.
Don’t Roll Back
The right foot stabilizes the backswing. If this foot rolls, the club will bottom out behind the ball.
Difficult to Fix
If you roll your foot on the backswing, the only way to reach impact is by rolling your foot back on the downswing. This maneuver is difficult to time properly, so you are better off keeping your right foot planted throughout the backswing and downswing.
