What are the advantages and disadvantages of keeping the back foot back vs. bringing it forward to serve? I am a 16 yo high school player and I have always used the pinpoint service motion where my back (right) foot comes forward right next to my front (left) foot. This has always been more comfortable for me but my coach is telling me I should use the platform stance where my back foot stays back. It seems that the pinpoint motion would be better because it puts me closer to the ball and I can use both legs to push off into the serve instead of just my front leg (which is weaker anyway). I have tried many times to do this but it just wasn't comforable and I felt I had no control over the ball at all. However, I tried it again today and it was working pretty well, but it hurt my left calf muscle because all of the stress was on it instead of on both right and left. Which is better? Should I seriously try to convert?
