As we move through the winter months, mirror work is a great way to keep your swing in check. Checking the club face is merely one thing to look at in the mirror. We can obviously look at your posture, your swing plane or whatever you are trying to change. Here are two things that I didn’t mention in the video that are worth doing.
1. Use a weighted club (like a momentus) and hold your positions for 2 counts as you go through your swing. This could almost be a workout if you do it long enough. It is a great way to create some muscle memory.
2. The second way to change the club face (that I forgot to mention) is how the hands set at the top
A cupped or bent lead wrist will open the face more and a bowed lead wrist will tend to shut the club face more. Neither of these are necessarily wrong, they just have to matchup to the grip and release (see matching components).
Good Luck with your indoor training and I look forward to your comments,
