I'm just updating my initial post, but I am finding this challenge is actually making me walk and do stuff even when I don't want to - like yesterday.
I need to mow really, really, really bad... That will be the bulk of my exercise today - pushing an electric mower through tall grass - that and walking to and from school twice to pick up the kiddo.
