"The last three or four reps is what makes the muscle grow. This area of pain divides the champion from someone else 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"

This quote by Arnold Schwarzenegger talks to the importance of pushing through the discomfort in order to achieve success. He highlights that the last couple of reps are what make the muscle grow, which it is this location of pain that separates champs from those who are not. He is suggesting that it takes a certain level of nerve and decision to be able to press through the pain and keep going, no matter what. This is something that many people lack, and it is this quality that can make the distinction between success and failure. Arnold Schwarzenegger is motivating us to have the guts to push through the discomfort and keep going, no matter what.
