If you stay on your left side when you hit the ball 100 yards in, is it ok to do that with all your clubs?
Mike says this is the Stack and Tilt method, and you are basically playing off your left foot. Force is going from right to left. You aren't trying to hit the ball as far as you can, but you are trying to control trajectory as much as possible.
Mike stands on his left foot and swings from 100 to 120 yards. When he gets outside that range and is still on his left side, he finds it harder to get the ball in the air. Also, Mike can't hit the ball as far.
When you are creating speed, it comes from the ground up. When you swing left, right, left, that whole change of force is a considerable speed producer that goes through your body.
If you stand on your left side, you have eliminated the loading of the shaft, and you won't hit the ball as far. You will hit the ball a little lower and more to the right.
Golf is about a blend of motions and actions. When Mike is hitting short shots, he hits from his left side. If he hits his driver with the same setup, he could hit it fine, but he wouldn't get the distance. Using the left, right, left motion allows Mike to pressure the shaft and become a big speed producer.
It's the change of direction in your body and the force it puts into your club.
Playing on your left side is a way to play, but after 100 yards, you will have to give up distance and speed.
