this has been something I have incorperated into my swing, something I never did before. For me it gets me into a better rhythm, rather then starting my back swing from a static position. in my swing it starts a pendulum motion and alleviates some jerkiness. seems to keep myself in a better tempo because I had a tendency to jerk the club back too quick, but a smooth forward press seems to have helped eliminate that. I would be interested in hearing of the different ways people forward press, for me I just use my hands and a small hip shift so my weight actually goes onto my left side a little and then the back swing starts when my weight shifts back.
