I have taken a few tennis lessons, but not very much…i am trying out for my highschool tennis team in a few weeks, so i really need to get in shape..i read that you need to run a lot..which im working on..but i def need to work on more..im 14 and im not too out of shape..but im not exactly in shape either..i go to the gym once or twice a week, is there any specific excercises i should do there?…or at home?? anything would help! thanks!!
