Width in the golf swing is important- especially if we want the left arm and the shaft to form a nice straight alignment at impact.
Whilst not all great golfers had a perfectly rigid left arm right throughout the swing-
it is certainly something that allows us to put a pure downward strike onto the ball at impact.
In this new video I explain how the left arm works it's magic
and it is probably not what you think should happen that enables this key to consistency to occur.
