Painting is a pretty good workout, think of it as tia chi for the artist.
Upper body- push, pull and chin ups, dead lifts and I have a set of rings that I do my upper work on.
Lower body- squats, skipping, running, riding
I once read a study that said if you thought about working out then you would lose more weight and gain more muscle then someone who does not think about working out. I do not know if it is true or not though.
