re: Any drills work to eliminate a bad over the top swing?

Take an old club
1. Take your adress & put your butt against a flat wall (pref. Brick if possible) your back pockets need to be against the wall not your front pockets
2. Take a SLOW backswing and trace the flat surface of the wall
3. SLOWLY drop your hands to let our clubhead trace the wall on the way down. If you club looses contact with the wall...START OVER
4. Stop your downswing half way and go back to the top of your backswing and repeat 4-5 times

Repeat process

Take a few practice swing away from the wall to mimick tracing the wall at a slightly faster speed

NOTE: BeaverPro does not take responsibility if you put a hole in your wall from trying to perform this drill too fast
