I've been walking for about 40 minutes each day since my summer vacation started. Before that, I was using the stationary bicycle for 20 minutes each day (and I'll probably go back to that when I start working again - easier to fit that in around my work schedule than a walk).
Today, I discovered that a pair of shorts that had been too small for years (literally) actually fit me comfortably now! I'm so thrilled!
