Address position - pitch elbow
 

I am swinger but found out that I release the right elbow quite early in front of the body with a punch elbow at impact.

My coach told me that this is due to my address position, too steep, (63 degree with a driver) and not enough left hip turn coming down. He said that no way you can have a pitch elbow if the left hip not turn enough, all good golfer has a hip 30 degree open at impact. Also, the address is too steep and won't allow a pitch elbow.

In TGM, we said, hand control, right shoulder start down etc.. so I never play attention on the left hip. So do I have to initiate the start dwon on the left hip to clear the left to have a elbow position?

Its much easier if you do not let your right elbow get out of position, i.e behind your right hip on the backswing, in the first place.

Start your backswing on that premise and the rest should just fall into place nicely.
