I haven't been able to play much in recent months and registered for a 4.0 tournament starting 1/16, thinking it will force me to get my game back together. Hit a little bit yesterday and my legs felt sluggish. Any tips/links on how to get back in tennis shape quickly? I'm 39 years old, quick around the court, but only started playing when I was 32. Still lots of gaps in my game, particularly first serve and net, but I'm slowly heading in the right direction year to year. Just moved up from 3.5 last year. Any help appreciated!
