At my gym they have this thing no one ever uses. It holds plates like a regular barbell and has handles but it is diamond shaped and I think you're supposed to stand inside of it. Looks like you could use it for deadlifts or shrugs. I've never seen anything like it before and I've never seen anyone use it, it's always leaning against the wall off to the side. I was just wondering because it seems like the things most people don't use are the most effective.
