08/09 Swimming in the gym...

This afternoon, my classmates pull me to go swimming with them. This is my first swimming in the campus since I came here one year ago. Before, I always go jogging, and this time I try different choose. Although the water lane is only fifty meters, I feel very tired compared with jogging...XD However, I feel very well, and I will go there again next week....^^ To exercise different part of my body, and enhance my cardiovascular system...
