This is why I like to take an exercise class. Even if the workout isn't optimal, at least I will go because I paid the money, and at least I will do all the exercises because other people are watching. The bike ride thing is pretty good too. Sometimes people make me so mad cutting in front of me that it will turn into a sprint so I can teach them a lesson not to underestimate this old lady. Other times it's just a nice relaxing activity that didn't tax me too much but left me feeling good.
