Thanks for all the feedback.......Tell me if I'm anywhere close on how to achieve stretch.
When taking a stride it should feel as if youi are walking away from your hands. ie hands behind back shoulder. Should this feel like the pulling back of a bow and arrow? What is the difference between stretch and seperation. I thought I knew what seperation was until this post.
The bow and arrow analogy is pretty close. When I simulate it, my front arm stays bent and I feel like my arms are working as a unit. A lot of girls will want to straighten the front arm when the hands load, which I don't like. When the hands load I want the angles in the elbows to remain relatively constant and the hands to end up close to the back armpit for swing launch.
Stretch: The hands load or cock during the stride. The feel is similar to how the throwing arm goes back as the hands separate in the overhand throw. The timing of the separation of the hands in sync with the stride when throwing overhand is the same in hitting.
Separation: Occurs when the front heel drops to trigger the hips. The hips will lead the hands by a fraction of a second. If the hips lead the hands then the hitter has created separation.
