Physique benchmark

How John Grimek measures up

Fat-free mass index turns the height and weight on this profile into one number for how much muscle a frame carries, so a shorter competitor is not flattered by a bodyweight comparison. The normalised figure adjusts it again to a standard height, which is the version worth ranking. Both assume the 6% body fat a competitor steps on stage at, because that is the only condition the recorded weight was taken in.

The closest Olympia champion on that measure is Erin Banks, at 31.1.

What this rank is not. This database holds a height and a weight for just 463 athletes, and they are overwhelmingly the ones somebody bothered to measure: 73 of them hold an Olympia title. Almost every competitor on record carries no measurement at all. The pool also mixes every division and era together, from the lightweight women's classes to the open heavyweights, so it ranks size and nothing else. It says where John Grimek sits among the athletes we hold measurements for, not among competitors.

Only 2 head-to-head meetings on record so far, with John Grimek ahead 2 to 0 - too thin to call a rivalry yet.

Opponents are ranked by how often they shared a stage and how big the stage was, not by reputation. A meeting is one contest where both competed in the same division and both were placed.
