Hoping Coach Houston will respond with his expertise, but in the meantime, there are several youtube videos on how to serve that may get you started. Now is also a good time to start looking for camps. If you need help finding a camp, post back with which country you live in as well as a couple close by cities.
I can say that initially getting the feel of making good contact and having control can be frustrating, but persistence and practice goes a long way.
I am glad you brought that up my mom just signed me up for a camp at Westmoreland County Community College for volleyball and I'm very excited everyone I know that has done it before said it was very advanced so I hope it can help me and before the camp I can look at the videos on youtube thank you for your help and suggestions
