I went swimming today for the first time in, uh, let's just say a while. I swam 1000m in 21 minutes, which is much faster than I had expected to swim. I wish I were better at working out regularly. For one semester, I swam two or three times a week, and I felt great. But now all those benefits have been lost due to not working out and too much junk food. Sigh.
Side advertisement, I use a site called Fitocracy to track my workouts. It's a fun site because working out gives you points towards "leveling up". Leveling up doesn't really do anything, but it's an ego boost and a way to see progress happening even when you don't feel like your body's making progress. It's free, or you can sign up for a paid version. I use the free version; I think the paid one just has some more bells and whistles. If you're interested in joining, click here! (That's my referral link. I don't get money if you sign up through it, but if enough people use it I get a brief period of free access to the paid portion of the site.)
