So, I scratched the stairs and WATP plan. I found a fitness walk On Demand that I thought I'd give a shot. It's a 45-minute workout and it kicked my butt! Granted, I can't do it as intensely as I'd like to since I'm on the 2nd floor, but it still was a good workout. I'm sweaty and tired and my arms are shaking from the resistance part. It breaks down into 5-minute intervals. Five minutes of walking, then five minutes of strength training and so on. Really good workout!
I may still do another workout later, just because I'm going stir crazy, but I do need to clean up around here before I do anything else.
