I've currently been doing all my lifting with a bench and standard bar/weights. I decided that in order to give my legs some real work without killing myself (Since I don't always have someone to spot me.) that I'd get a power cage and olympic bar. Well I got it, but there's a small problem. I don't have enough room for all of them :(.
My backup plan is to put them in the back yard and do my lifting out there.
Exactly what maintenance would be involved in I were to keep in out there?
