Whats wrong with my 2HB?! :? I have no problems with 1HB. The ball flies easily, just like my forehand. But when I use my left arm for a 2HB, it feels cramp and I got no hit on the ball at all. My left arm is cramping and my balls is landing all the time in the servicebox. I feel so weak in my arms on 2HB, but not on my 1HB. Whats wrong with my left arm? Do I have to change my takeback with a loop instead of a straight takeback or whats the problem????! What should I do to feel power in my arms, just like on my forehand and 1HB? THNX for your answers!
