golf machine advanced ball striking lesson

advanced ball striking maintain cup in left wrist so club head follows path back. back of left hand aims at ball. when downswing starts, thrust right hand at ground and ball. maintain cup even after ball is struck club should swing in to out. this compresses ball properly. if knockdown shot is desired, move ball way back in stance, and exaggerate cupping of hand. hold cupping while swinging club further through the ball down the line. driver swing. even more in to out. for this the club bottoms out and then goes up into the ball. to swing on the proper path, (back of left hand at ball) i have to thrust right hand at the ground right away. i am still working on coordinating the hip turn. for the time being, i will not exaggerate the down the line backswing because i can't get my weight to the front properly yet. my flaws are tempo (tend to be quick on backswing) tend to pull club to inside on backswing rather than extending down the line. fail to use hips cupping the left wrist and keeping the back of hand at ball seems to automatically shorten the backswing.
