I teach and tutor full time. About the only days I do not tutor after school are Fridays. I go to a burlesque class on Saturdays for a full hour (a lot of fun, I might add) but I feel like I can do more. I try to hit the gym Fridays and Sundays, but can anyone recommend a mini home work out that doesn't involve any equipment (our apartment is tiny) that I can do on the days that I'm running around from 5am until 8pm?
