I ended up using my Wii Fit. It was fun, but I really need about an hour for Wii Fit to be effective and I only had time for 30 minutes. I called Comcast and they scheduled a service call as there were no known issues. When I came home at lunch On Demand was working.
This evening while sitting around watching TV I decided to get off my butt and did Wii Fit for about 30 minutes. Now I feel good about getting back on a workout routine. My plan is to get up at 5:30am Friday and do 30 Day Shred. I figure I'll do every other day to start and work up to every day. I'm sore from tonight.
