This is a great way to get people to turn their shoulders fully on the backswing.
Derek himself has a habit of getting tight and short with his backswing when under pressure or not feeling confident.
By getting Derek and our pupils to look at something or someone directly behind them in a practice swing it just seems to release some of the tension and frees up their turn.
Just make sure to take the same feelings from the practice drill into the real swing, but keep your eye on the ball.
With juniors we call this the pantomime drill as we will have a coach standing behind them and shout he’s behind you!
Turning the shoulders fully helps to fix a slice and is a great source of extra power if the pupil makes solid contact with the ball.
