Badminton weekend

I went to play badminton twice during the weekend, and feel I can stand for the 2 3-hour playings which was impossible two months ago. This means my stamina is getting better. Although parts of my body are hurting, I feel I am physically stronger. The exercise and jogging do me a lot of help.
I also played tennis twice during the evenings. On Saturday, I escaped from TV to avoid watching Gators' 4th quarter and went to practice my serve. On Sunday, I played with SD and AL for 1.5 hours. Then I have hard time to go to sleep because of the sourness of my legs.
