I've been looking to lose some weight and get in better shape lately, but don't really have ready access to a gym because of life circumstances. Figured I'd throw this out there and ask for some advice about working out at home to lose weight with no equipment. I mean there's the obvious push ups, situps, etc. But I'm more looking for advice on how many sets/repetitions, how many days a week, etc. Obviously I plan on dieting a bit as well, but any advice or some kind of link/graphic showing a few basic workout plans would be appreciated.

I figure this post can help some others in the same situation as well given a lot of us want to get in better shape to prepare, but don't have access to the best facilities, and whatnot.
