Golfers get in more trouble on the first part of the takeaway doing all sorts of nasty things. Below is a drill that shows the only way the hands need and should work in the back swing. The drill splits a proper takeaway into two parts. The hands hinging the way they are supposed to and the shoulders turning. All you have to do is sync up these two movements at the same time.
This drill is great at showing you how each part is supposed to work, then all you have to do is combine the feels…and it is easier than you may think.
