Hi, After one year of once a week instruction, I've changed instructors. I felt I was not improving. So, today, my new instructor taught me the continental grip for serve. The only problem is, I can't do it right. My outer-arm hurts, my balls are flying all over the place - they aren't even going over the net. I feel retarded. I was using the "frying pan" grip - whatever that may be and having some success but not reliable. My instructor said with the continental grip, I will have more options for serves and more power. I am definately willing to continue trying, but I can't even play a game with this serve. I need some help. Do I stick with it and hope it will work? Are there any tips? Why does my arm feel like it is going to fly out of the socket? I appreciate any advice.
