Watched a guy come in and put 15lbs on one side of the bar and 10lbs on the other, for a total of 70lbs, then OHP with horrible form (probably because there was more weight on one side of the bar). I was about to go over and mention it to him when he turned around and OHP from the other side of the barbell, so that he was now using the opposite side for the heavier side.
He did 5 sets like this.
I'm not sure what the point was. If you are trying to work one side harder than the other why would you then switch? If you want to work both sides equally why not put the same amount of weight on both ends?
