Enhance rhythm and feel
What to do:
Starting with a wedge, work your way up the bag hitting one shot with your eyes open, then one with your eyes closed. Once you've done this, pick a club you struggle with and hit a succession of shots, all of them with your eyes closed. You'll find that even only after a few shots your feel will be greatly heightened. In order to find the center of the club-face, your setup, rhythm and balance must all work together. This drill increases your ability to make this happen, building confidence in your natural swing.
How I did:
My first attempts at hitting balls with my eyes shut were pretty embarrassing, so I wouldn't expect flush shots immediately. Stay patient and don't try to overwork the club. Just make a loose, rhythmical swing, letting the ball get in the way. This is what I had to do, and after a while I was able to find the center of the club pretty consistently. What I also noticed is my ball flight straightened out dramatically. Part of this surely has to do with a slower club head speed. However, because your swing falls into proper sequence, minimal distance is lost.
Beginner- try chipping and pitching with your eyes closed before moving on the full swings
