Oh, Monday I decided to try the Bounce class at my gym again. I had a lot more fun this time. This is not why my knee hurts. My knee actually started bugging me after my Sunday run. I had more fun doing it this time. It was definitely a great low-impact workout. I'm not sure that their claim of 10 minutes of bouncing is equal to 20 minutes of running, but taking the class will certainly help my core strength.
Tomorrow is 2-5. I'm going to aim for 4. I might get my lazy butt up and do it in the morning. I teach on Thursdays, so normal gym times aren't available. My other option is to take my running clothes with me and run around the college campus. I can always go to the gym when I'm done, but I feel like I should take advantage of the hills and decent weather available to me on the campus.
Keep on chugging!
