Practice swings in your full swing are over rated but in your short game they are a must!Every shot you have around the green, be sure to take 1 or 2 rehearsal swings. But make sure they are productive. These rehearsal swings should be the exact length and type of swing that you want to produce over the ball. Also be sure the club is brushing the grass and making a solid impact with the ground, this will promote solid contact with the ball. Then simply set up and repeat what you rehearsed!
