I'm trying to develop a training plan for the summer months which incorporates all three activities (tennis practices, tennis competition, weight lifting, and long distance running). Tennis games on Saturday morning. Tennis practices on Tuesday evenings. Tennis lessons on Monday evenings. Any thoughts on how I should incorporate weight training and running into this weekly tennis schedule? I'd like to add ~ 10 lbs of muscle and keep in decent running shape for 5 - 10 miles.
