I've learned my lesson. There have been many times when a meeting has been canceled, a friend invited me on an impromptu run in the park, or I finished work a little early. These were perfect times to fit in a workout, but I had the lamest excuse — my gear was at home. So now I keep an extra outfit and sneaks at work or in my car, or I wear workout clothes if I've got nothing going on that day. So if an opportunity to exercise presents itself, I won't have the excuse that I don't have anything to wear.
