This is true - the author asserts that there are more ultra healthy people now than at some point in the past with less abundance, but this isn't obviously true. This isn't about steroid use, there is some aesthetic popularity to body fat levels that are probably not actually healthy, as well as some pretty dubious dietary practice that also overlaps in practice with the same population. On the other hand the regular exercise part is clearly positive.
