Golf Swing - Vertical Ground Reaction Force

Wrist release correlates highly with club speed, like the angle between the shaft and lead form. At shaft vertical downswing, we want this vertical ground reaction force to be as high as possible. If you were doing a netball slam at the point in time where you were forced on the netball pulling down was peaking, you would actually see virtually no vertical ground Reaction Force under the feet. That's the sign that there's a reason why we're doing that.
