Foot action lets you transfer ground for effectively through your body. Start to get a feel of this by keeping your feet flat and making swings with the club.
Once you can swing with your feet flat on the ground, start to let your feel roll in one after the other. This will give you a feel of sequencing as we build into your full swing.
Foot action cannot be overstated. This is where your power comes from. The more you can sequence this out in your swing, the more consistent and balanced you will be.
Once your shoulders are working properly, swing level as though you are moving the club along a table. This will ensure an uncomplicated face rotation, avoiding hooks and slices.
