There've been a few threads where some members (notably charlie federer) have advocated keeping the tossing arm parallel to the baseline. This video advocates it also: http://www.youtube.com/watch?v=lIF-UaRUd6k (although, as with much of his footage, it's sometimes hard to really see the angles given the camera angle) Now I get the wisdom behind keeping the tossing arm parallel - it facilitates proper body rotation of the hips and shoulders. The problem, at least for me, is that I find it extremely difficult to keep the tossing arm parallel to baseline, while at the same time allowing the contact point to be inside the baseline. I brought up this point in another thread where charlie was helping me with an issue, and he said that I should use the J-toss, and showed a gif of sampras doing it. The thing is, the j-toss doesn't do anything for making the ball go forward into the court - all it does is bring the ball closer to the server's body. Now for a kick serve, this is perfect - a parallel tossing arm combined with a j-toss means that it's easy to get the ball to be above the server's head. But for a flat serve, or a serve where you want the contact point out in front, it's really difficult. I spent a good hour on the court trying to implement the parallel tossing arm, while at the same time tossing out in front, and it was absolute havoc! The variability of my tossing location was atrocious. Is there a way to get a good healthy reliable body turn but without a parallel tossing arm?
