I used to use isometrics pretty heavily. That style pretty much means you do not use much equipment at all. For me it was an old sturdy chair and a heavy couch to pin my feet under. Diet for weight, exercise for strength. I used good portions of the Charles Atlas program. I skipped his diet as I was not looking for body building. Just kept myself under my 1100 caloric number (varies on height and age). Just wanted some strength and not be fat.
