How one bends to the ball... can greatly influence their golf swing(stroke). The Bend from the HIPS, or this is sometimes called WAIST BEND, the Bend of the KNEES(how much flex), and the Bend from the NECK.
Let's discuss exactly how one should bend to the ball. Tom Tomasello used to teach to bend with the knees locked, then unlock the knees, then "sit a little." He liked the back fairly straight, and the head UP. That was part of the routine. This is one way. I know there are others. Include in the discussion... variables, such as PELVIS DIFFERENCES, FLEXIBILITY, LENGTH OF LIMBS, ETC.
