If I didn't work in a warehouse, I would lift weights, because it just helps you in every day life. If you have to help someone move, or do anything else that requires strength... it's good to have it. Also, it just helps my appearance. I look better with the slight bit of muscle I do have, rather than flabby fat or the outline of my bone. It's healthy as well, which really isn't a factor for me, considering my several other terrible health habits.
