Six months of running 2 miles a day will give you a good foundation. Drill on stopping, starting and changing directions. Short-distance sprints also will help. Strength training is vital in preventing injury. In tennis, the trouble spots are the shoulders and lower back.
Back extensions are great for strengthening the lower back.
For the shoulders, I recommend push-ups. To improve players' line of sight, the stadium was aligned to make best use of the sun's position Monday, midway through the U.S. Open.
