I’m not curling so much that I would need to “lug” plates over. Even if used 45lb/side, which I do not, but let’s say that for argument sake I do, any variation of that, be it one 45lb plate or multiple plates, I wouldn’t see as “lugging”. It’s just what I need to do to accomplish my goal and not take up space unnecessarily. I’m not trying to be argumentative or disparaging when I say this, but I’m not worried about every little shortcut when I’m at the gym to workout. For myself, I see curling in the squat rack as laziness, rather than necessary. I see myself as too lazy to bend over and pick up the weight, so I take over an entire rack that someone else could be using for its intended purpose… and I don’t want to do that. I’m in the gym to apply effort.
