In conclusion, one can fairly say that the lean BMI or body weight of modern professional top bodybuilders is about 40% higher solely as the result of massive use of very potent hormonal drugs such as androgenic-anabolic steroids, human growth hormone, IGFs, and insulin. This is more or less consistent with the observation of nowadays natural bodybuilding contests, where the BMI-values of the champions are rather close to 25 than 30. It is therefore fair to say that today's top heavy weight bodybuilders have more than half of their lean muscle mass thanks to the drugs, rather than hard training and good nutrition. No, the steep increase of lean muscle mass among top bodybuilders since the 90's has nothing to do with better genes, better training, better nutrition or supplements. Unfortunately Ronnie Coleman does not come from another planet, as many of his fans would like to believe.
For several years in the mid-1980s, NBC broadcast coverage of the Ms. Olympia contest on their Sportsworld program. The taped footage was telecast months after the contest, and was usually used as secondary material to fill out programs featuring events such as boxing. Typically, the broadcasts included only the top several women. Nevertheless, Rachel McLish and some of her leading competitors were receiving national TV coverage. McLish authored two New York Times best-selling books - "Flex Appeal" (1984) and "Perfect Parts" (1987) – and was also starring in action films. The popularity was growing and women were being empowered and inspired to train. In 1983, the top prize money for the women bodybuilding was $50,000, equal to that of male bodybuilding.
I have to agree that the only valid point is the first one. The other points would be negligible at best and certainly not affect a high level natural bodybuilder. Body builders eat often but not such obscene amounts of food at a time that would make their stomachs protrude chronically. Heavy lifting also just doesn’t make your stomach stick out like these guys either. Maybe genetics could play a roll but I really doubt that too, particularly with the pros. Make no mistake at all, bodybuilders with stomachs like this are on or were HGH and/or insulin injections,.
