Jeff Everson said, "Until Pigs fly you don't have to be a scientist to be a bodybuilder." He was dead on target. He pointed out some champions are always talking about studies and the latest research. Some couldn't tell you what they ate or how they trained the day before but both could be champion bodybuilders.
There is no magic or secret in bodybuilding. Everyone is looking for the magical split. The magical amount of sets and reps. Fail on the first set, third, sixth or not at all? I have been obsessed with reading about exercise physiology and everything bodybuilding related. The more I read the more I realize there is no revelation to be found. Truth be told if you had no knowledge but a determination to have a good build you could accomplish that lifting rocks in your back yard.
A work ethic, genetics and yes, what drugs you take will determine who gets a trophy posing oiled up in a speedo.
