Swing the putterhead

We're all attempting to learn how to 'swing' the club. But some may forget this most basic of all functions of the club when putting.

'Swing' means the clubhead moves further and faster than the grip end. If the grip end and the head move at about the same rate, there is no 'swing'. A good swinging action gives us a solid strike, proper distance and consistency. Lydia Ko demonstrates the classic swinging action:

At no time does the putterhead stop moving faster than the grip end. The stroke is rhythmic, continuous, unforced. On the forward stroke, she is allowing the head to contact the ball with a square face. This is difficult as our instinct is to aim the face at the target during contact. 'Aiming' the putter i.e., guiding the face along the target line, results in decreased swinging action and inconsistent distance, for one. 

So your idea when putting should be what? 1) Ensure the putterhead travels fairly down the target line with a 2) square face. Then, when the putterhead is in motion, do not aim it. Simply apply the required length/speed to the stroke the distance requires, without aiming!!

My book, "The Y Shape", has more good info on this and exercises to help you putt better. http://www.theyshape.com/Y%20Shape%20Info.html
