Experiencing this pain in my muscles and aching and going on and on is my challenge. The last three or four reps is what makes the muscles grow. This area of pain divides a champion from someone who is not a champion. That's what most people lack, having the guts to go on and just say they'll go through the pain no matter what happens. I have no fear of fainting. I do squats until I fall over and pass out. So what? It's not going to kill me. I wake up five minutes later and I'm OK. A lot of other athletes are afraid of this. So they don't pass out. They don't go on.
