What It Is
An easy way to stop you from moving your hips and midsection closer to the ball through impact, an error that typically leads to weak shots that leak to the right and overall poor ballstriking.
How To Do It
Follow these steps:
1) Set up with your backside against your golf bag.
2) Swing your club to the top while maintaining contact with the bag.
3) Swing down through impact, making sure to remain in contact with the bag
The secret is to focus on each cheek: Touch the bag with your right cheek on your backswing, and with your left cheek on your downswing. Make sure you rotate around your spine instead of moving laterally and you'll have an easier time doing this correctly.
