I would focus on mobility, some one legged exercises, pulling exercises and a few heavy lifts such as front squats and lunges. Nothing too hard on the joints. Mobility exercises allows a higher range of motion which helps keep injuries from happening. One legged exercises shows weakness on one side that can result in injury if you don't take care of it. Pulling exercises are great to balance the repetitive forward motion that tennis players do. Hope that helps!
