First, no. Second, so what. Even if you are tired that does not mean you should sacrifice exercies form. You should use less weight. That is why accidents happen and that is why Branch has had so many injuries. Third, both legs matter. He was not doing lunges with the trailing edge on a bench. Fourth. I agree with you. He is going to have the biggest and most ripped legs on stage. He has very good genetics for "cuts".
