I am currently playing a lot of tennis, over 2hrs/5 days every week. I'm taking the sport relatively seriously and am looking for any edge I can get to improve. Obviously, all of the pros do a lot of work in the gym to improve their footwork, strength, and stamina. I currently have access to a gym, however because of work constraints....I really don't have enough time to play tennis for a couple hours, then hit the gym. I was thinking about doing some drills and fitness exercises perhaps before or after I play for like an hour or so. For instance, I was thinking about doing some jump rope, carioca-type footwork drills and maybe light-plyometric exercises. What do you guys think? Any of you tried doing this? Any input on this matter would be greatly appreciated.
