I feel all my muscles working together to unwind from ground up... as if I was throwing a ball. Here are a couple things:
1. If you use your hands to hit at the ball through impact, the body stops rotating to "support" the hit (not good). Just like if you were chopping a tree... your body unwinds at first to a point where is stops and the hands throw the axe head into the tree. We MUST keep the hands from hitting at the ball and use the body's rotation to move the ball. You want to visualize accelerating all the way to the finish. 2. You also must have more of your weight on the front foot to be able to unwind and turn. At the finish, you'll have 95% (or more) of your weight on the front foot. Your knees touching at the finish is a "side effect" of having unwound correctly and completely. Nothing moves independently. 3. Remember... you have to wind up (backswing), correctly (top down), to have created the potential to be able to unwind on the downswing. For instance: if you moved your hips and shoulders together on the backswing, you did not create any wind up... so on the downswing you can't unwind, because nothing is really wound up. It is like a "false" backswing. Once again, the best way I can explain the feeling is like throwing a ball a long way... the body unwinds to bring the arm through and you let go... the body does not stop half way the the arm takes over.
