However, 90 degree L blueprint, or as Ursa calls it, "a braced position" at contact, WILL stiffle the release phase of the swing, and the kinetic chain that transfers momentum to the bathead........As well as the concept of being long through the hitting zone..........
The only way to reach extension from that braced position is to "push" the fulcrum forward.........
That position should be a spot you move through during whip not a position you hold. No "bracing" or "resisting" at contact makes any difference if the experts who tell us the shock wave from bat ball contact only reaches the hands well after the ball has left the bat.
