> This causes many to simply assume that what they did is the "correct" way to workout when the truth is that had they dont most any routine with that devotion for many years, they would have gotten similar results.
This. A great example of this is Tim Ferris and The 4 Hour Body. That guy basically says "well, here is what I did, and here's what I look like now. Do exactly as I say and you will too." His "research" has a sample size of 1, yet he claims that his method will work for anyone in the world, from a skinny teenager to his overweight mother. True, it will work for some, further muddying the waters.
