Wow! A certification that actually requires you to walk the walk as well as talk the talk.
This board is full of *very* fit people, but I don't think there would be more than a handful that could pass that cert. Maybe... and couple of hands full.
And I'm not even half of one of them.
One thing for sure, it does not require you to be "Cross"-fit. It is very strength + strength/endurance focused, so doing things like running any further than 50m is wasting your time. It does, at least allow you to concentrate your training on some very specific, relatively narrow-focuses goals; provided you are willing to sacrifice other areas of fitness.
