I wasn't saying it is the only way, but generally accepted. I love training low reps, I just like it better. But during this cut, I'm going to incorporate equal numbers of low and high rep sets and see if I can reach the goals I have set for myself. I put on a lot of muscle using low reps, but 8 to 12 reps might be just as effective for a lot of people.
Leaders are made, they are not born. They are made by hard effort, which is the price which all of us must pay to achieve any goal that is worthwhile. - Vince Lombardi
