If you have somebody you really don’t like and they’re hitting the ball too far and playing too well, have them do the towel drill because there’s no better way to ruin a good golf swing because it applies force to the body and the club that we don’t need in a golf swing. You don’t want to swing a golf club feeling like you’re pinning your arms to your chest.
If you want the golf ball to travel farther, you want your arms and hands as far away from your chest during the swing as possible. The further the handle of the club travels, the more speed you’re able to create. This idea is restricted when your arms are pinned to your chest using a towel.
