This doesn't really classify as "working out", but the least you can do is put your ironing table one one end of the room and your sewing machine on the other, so you DO have to get up and walk some steps while you are sewing. Maybe store some stuff upstairs so you must climb stairs every so often? And keep the snacks in the kitchen!
eta... sorry, should have read all the posts to see that these ideas have already been mentioned!
