"One set at extreme intensity does the muscle-building job. It must be stressed that the one final, all-out set I do takes me to the very limit of my capabilities. If you feel you can attempt a second set, then you couldn’t have been pulling out all the stops during the first set. It's not pretty, but it works"

In this quote, bodybuilding legend Dorian Yates stresses the importance of pressing oneself to the extreme in order to develop muscle. He believes that one extreme set suffices to achieve the desired results, as long as it is made with optimal effort. Yates stresses that this final set needs to press the body to its absolute limitation, leaving no space for a second set. He argues that if one feels they can do a 2nd set, it indicates they did not give their all in the very first set. While this method may not be simple or aesthetically pleasing, Yates thinks it is the most effective way to see lead to muscle building.
