“Balance in your golf swing must be dynamic. Threatening your balance when you practice will teach you perfect swing technique” – David Lee
This particular drill is one of the fundamental “Gravity” golf exercises in that it teaches the student so many aspects of the dynamic balance in the golf swing. Because of the balance demands of the cross-footed mode, it teaches the proper origin of the backswing (which muscles participate), the intensity of the initial movement (the heave) that starts the swing, how to be soft in the transition from backswing to downswing, how to correctly make the all-important counter-fall, and how to fully release tension in the delivery.
This is also a fundamental drill for teaching the entire short game because it prevents the player from shifting weight to the rear foot in the back-swing. In swings where maximum power is desired, it is necessary to shift the weight from foot-to-foot like a pitcher; in short shots the body does not need to fall this far to create enough power. When you watch this video, the beautiful flow of a proper “Gravity” swing can easily be seen.
Doing this drill awakens the same part of your brain that taught you to walk, and adapts it to training all your swing movements simultaneously.
