Meh. For the sake of argument, allegedly 100% of the IFBB is on steroids, same with professional Strongman, OL, Powerlifting, etc.... Yet Rhado is very, very rare. Where it is not so rare is Crossfit, in fact it was so common in Crossfit it had it's own meme that was a mascot in the early days -

And if we google "GHD Sit Up Rhabdo", you get 14,000+ references. If you google "Crossfit Rhabdo" you get 85,000+ across a broad population, not just elites.
Also, you can look at her Instagram, and sort of tell that she's not an established Crossfitter, used to all the movements, time protcols, etc.... So you can't make the argument that she may have adapted somewhat to it.
