Getting your right elbow, (for right handers) is a risky move. You’ve probably heard of stuck and behind you? Once you get your right elbow behind you in the back swing you make it difficult to get the golf club back in front of you at impact. Your only resolve would be to throw your hands at the ball which could cause a snap hook. Most likely you will bail the ball out to the right because you can’t recover.
Here’s a drill that might help you. Byron Nelson used to talk about getting your right elbow in your gut on the downswing. Same thing really.
Try this drill.
