The question I was asked via an emailed query is very straightforward :
You constantly refer to “leverage” as the source of MCS power. No doubt you’re right. But I wish I had a clearer idea of what is being levered, what mechanical advantage is obtained thereby and how this increases clubhead speed.
There are two “arcs” in the swing which must be understood if one is going to swing optimally, as they are not as you see in video or pictures – they are an optical illusion, actually.
The first arc is the vertical arc which, as I have combined two pictures that show the blurred arc of the club head before and post-impact, to show you what is meant by “descending,”“level” and “ascending” impacts.
