I coach putting in the same way as I coach the rest of the game.  I keep it as simple as possible, and I try to let the body work naturally, rather than fighting against it.  As with the rest of the game there are a few basic fundamentals that are the foundations of a good stroke, and these fundamentals are what I spend most of the time helping people with. 

A good putting grip, (which is very different to a conventional full swing grip), a good setup, and a basic understanding of the way the putter moves is all you need to be a really good putter, and to transform your game on the greens.

The main thing to understand about the putting grip is that is very different from the grip used to hold the club for hitting a full shot.  If you are using the same grip to hold your putter as you do for the rest of your clubs then this is probably causing you problems.  The main thing we are looking for on the greens is touch and feel, rather than power.  The hands also work in a different way in the putting stroke than they do for any other shot.  This means we need to arrange them on the handle of the club in a different way in order to be effective.  The putting grip can be summed up with two words; 'lifelines' and 'fingertips.'
