There are two ways to hit a golf ball. One is called "hitting" and the other is called "swinging". Let me explain the difference and why one of them is a better goal than the other.
Accelerating the club into impact helps compression of the strike. It helps the hands lead the clubhead. It also helps avoid the clubface shifting in alignment. So why does the late hit matter most?
This video explains how the right arm can stay bent at impact if you follow the simple rule of the right arm structure on the downswing. This video ties in with a recent video of the same name.
Here is an important video explaining how the left arm & left wrist and their orientation affects the clubface. Its why I teach drill one as I do, and it can help your consistency.
