The most common issue I find for beginning golfers is not the set up or even rotation. It is how to start the golf swing and take the club away properly. Without a proper takeaway we have no chance at a great golf swing.
We want to feel connected with the golf club as we take it back and to the top. No rolling of the wrist or lifting of the club and our body.
At the halfway point of your backswing you should be able to take your trail arm hand off the club without moving the club and shake someone’s hand.
