Tiredness and serving question?

Question

when i play tennis for about 40min or more, my arm gets tired and i can't serve as well. what can i do to prevent my arm from getting as tired. what should my first serve usually be? should i slice, hit it flat, or hit with topspin?

Answer 1

To prevent your arm from getting tired you just have to keep practicing.  You will build the "serving" muscles and you will be able to play a lot longer.  Your first serve should be a hard but accurate serve.  There should be some slice on it but not too much or you'll lose the velocity.

Answer 2

Do stamina exercises for your arms using light weights.  You're not necessarily trying to bulk up your arm muscles, just increasing your stamina.

Answer 3

Drink plenty of water to keep u from getting tired, and take a little break before its your time to serve. Like 15 seconds or so. Thats what I do.

Also, do push ups daily to build stronger muscles. That is what I am currently doing every day. Practice at least 45 minutes a day playing tennis, and do around 100 push ups if possible.
