In golf, putting is the most individual part of the game, and many different styles and grips can be effective. You need to find a method you feel comfortable with. This is very important in putting.
First you need to position the putter. Then place the putter head flat on the ground behind the ball, aiming at the target and let the whole club sole rest on the ground. Next find the right position. Stand parallel to your target, keeping the ball slightly in front of the middle of your stance. This will ensure better connection on your upswing. Your feet should be approximately shoulder width apart. As long as you're comfortable, it can be a little less or a little more. Then simply lean forward from the hips until your eyes are directly over the ball. Keep your eye line parallel to your target. This gives you the best position to see where you are aiming. Then keeping your weight on the balls of your feet, just flex your knees slightly without reducing your height. Yours arms will hang free in front of your body. Start with your arms hanging naturally, and place your palms on either side of the grip. Third choose the right grip for golf. Always grip your club lightly to get the best feeling for distance and a smooth putt. An alternative is the reverse grip. Put the right hand on top of the left. The right forefinger is over the first two fingers of the left hand. This grip will naturally raise your left shoulder, angling your upper body into position behind the ball. Then slip your right thumb into the groove of your left hand. Some right-handed people find this grip easier to get their shoulders square, leading the swing with the right hand.
