Fitness Professionals Fail to Understand Survivorship Bias

So many fitness bloggers and professionals fail to understand survivorship bias. They model their advice around what they see working best for a handful of outliers with little regard to safety, recoverability, or sustainability. In their minds, willpower is the limiting factor, and any failures rest with the individual and not their training protocol. They look for successes as proof their training advice is solid and never question if a safer path would have yielded the same or similar results.

Things get really confusing when some of these fitness professionals demonstrate signs of brilliance with their understanding of nutrition or other health topics. But when it comes to resistance training, they fail to question the failures of conventional wisdom as anything more than a failure of the individual.

How the mind of a fitness professional gets warped is understandable. Those that get results will stick around, those that don’t will go away and will be replaced with new clients. Over time, the trainer sees more and more successes, which they believe are in part a result of their expertise. The failures are hidden. The successes are now financially supporting the trainer. Those that can train more often and recover faster are the best customers.

I could go on and on, but I think this is the root of many problems in fitness. Fitness advice is geared towards survivors, not towards reducing the failure rate. Instead of seeking the minimal sustainable dose, the industry pushes recommendations to higher than necessary volumes of exercise. When you question their recommendations, their defense is to point to a handful of survivors as evidence their way works. Failures be damned.

In this post, I use the term “successes” as those that survived the workout protocol used by the outliers.
