Good question. I warm up a lot. It takes me a while to get loose in the cold. I wear a long sleeve shirt under my standard tennis shirt. Once I get warmed up, I lose the pants and just wear shorts. And NEVER sit down at changeover!
Like the rest of ya'll, it take a long time to warm up, and then like the Mayor, the sweat pants come off, but not necessarily the layered top. The biggest problem I have though is keeping the hands warm, and the grip "moist" enough to keep a good grip while swinging away. Because it gets so cold, the handle becomes very dry and hard to keep hold of on hard shots. I have had to resort to the "stickier" grips during those months. I also always worry about breaking strings faster, due to the cold weather. Guess that is why we take back-up rackets. What I have found though, is only "real" players play in the cold, others find excuses.
My problem is that there is not time enough in the day after working, taking care of the honey do's, and dealing with kids to spend as much time as I would like to on the courts. So I don't care how cold it is outside. If the courts are dry, I am there. Call me crazy.
well i live in southern cali so i guess cold is a relative term no lol
But when it gets cold for us, i go out there in sweats and just do a light hit until im warm...i might take a jog if im the first one there...if not then it's light hitting. We often have to wait to play in bewtween sets and sometimes i would bring out some hot water and hand warmers to stay warm while i wait...
then again, im a big sissy when it comes to the cold... :)
