I'm going to start Tennis soon, but I need some advice in muscle building?

I have everything ready to play tennis and will start playing soon.


I was wondering if I truly needed to work out ON TOP of playing Tennis. Im about 5'9 160-ish and have a decent amount of muscle on me. I was considering to start taking a multivitamin, and L-Carnitine...helpful?, and also should I drink NaNo Vapor before tennis to increase muscle size? Help me out!I'm going to start Tennis soon, but I need some advice in muscle building?
Did you searched the internet? I mean you can just have free informtion which I think is a good idea, but a hard one though, or you can just buy a book from your local library or an e-book, it is your choice, I prefer reading books though, you can find what you need in the below links ... if you willing to pay some money. If not just go with search engines
