All or nothing

Today was the start of my new self-imposed schedule. I was at at my desk at 7:15 AM and I was cranky. Then apparently I was feeling rather fit, when in actuality I am on the unfit side these days. It was raining, so a couple of people and I decided to walk up and down 18 floors of stairs. Then I ended my day with a 30 minute ab class followed by an hour of aerobics. Everything hurts except for my ears. 'Everything in moderation.' I firmly believe this applies to exercise.
