Damnit! So I've been working out for a few months now to try to reduce soreness from serving in tournaments... Didn't help this weekend. I did discover that Motrin is a major help though. Anyhow... What muscles should I try to work on to prevent them from getting sore during tournaments? How do men on the tour serve the big heat through an each match in entire tournaments? While I'm busy with school and work, I usually have at least an hour a day (in addition to tennis) which I can devote to exercises that will get rid of this damn problem! The particular muscle I am referring to is on the outside of my arm (If I fold my right arm across my stomach, the part of my upper arm that faces forward and to the right is the most problematic). This is the tricep I am assuming? I do two or three different dumbell exercises for these, but maybe I'm doing the wrong ones?
