Forgot to post this yesterday, but in the morning I started day one of exercise. Pushups I did Week 1, Day 1 at the highest of the 3 intensities, situps I did Week 3, Day 1 and the second level of intensity, and squats I did Week 3, Day 1 at the highest level. Pushups, then squats, then situps. Repeat, over and over.
It was hard, but I got through it, and was surprisingly not very sore for long afterward.
Other than that, it was a pretty crappy day for a variety of reasons that I won't go into here, but at least I had my mom over and she and I and the kids had pizza together, and that was good.
