I am going to start working with a fitness coach soon and was just wondering what we should work on. I'm a developing junior probably 5.0, 5'10 145. I've had some injuries, but this training is primarily to build strength and flexibility, along with preventing injuries. We will be working once a week and then I will be doing my workouts he gives me on the days I don't see him. He's not a tennis player, but a great fitness coach. I was wondering what you guys thought was the most important thing for a junior to work on. Thanks.
