Umm, I think my gym has the "Frank Zane Leg blaster". The "harness" you put on your shoulders with plates to your sides and you hold a bar at waist level? I've never done it, but have been tempted just to see. When I see people doing it, it's like a squat motion with upport by hands. Usually women and weak old guys. But I did see one guy using it with plates stacked on both sides to the max!
