It seems to me that tennis works in a two day cycle. One day, say your first time hitting in 1 week, you don't hit great, but you still hit. I typically force myself to try hard on these days to get my gave back in shape. Then, the next day, you hit great. Typically, what seems like the best tennis of your life. Then, the next day, you play well, but not great, then you play great the next day. This then continues, for a while until you begin playing a lot and are pretty consistent. So, this always seems to be happening to me. Does this happen to anyone else, any reasons for this? thanks.
