Obiouvsly there are many ways to hit the ball on the other side of the court. What I believe is that it is impossible or so to produce an heavy ball without producing an high raquet head speed... and by dragging the arm whit the trunk i don't believe it is reliable.

Sure, the more fast we want to swing the arm, the more we have to be able to rotate the trunk fast, that mean great body and legs work .. but not the opposite.

Ironically, a too fast trunk rotation can disturb the swinging of the arm instead to help it on swinging fast.

I believe that good athlete can hit 100 mph FH without trunk rotation, by using just active arm motions. He will never be able to do that with passive arm relying on whip effect. I tried it many times and always got pathetic FH
Agree Toly, exactly what I would say.

Absolutely agree Max.
