What do you do for exercise?

I was wondering, and thought it might be fun if everyone would be willing to post what kind of exercise workout we are doing, and if you vary it from day to day, and what you like about your routine, whether it's walking, running, swimming, biking, weight lifting, aerobics; where you exercise, gym, outside, at home, etc. and the time and intensity and also cool down. I figure that we could learn something new and benefit from eachother.
