Oh no, it'll go a lot further than just screwing up our advertising--it will make it impossible for our coaches to do any personal training in states with licensure requirements, unless they have one of the approved certifications. We know this because we've actually seen the state law proposals over the last decade.

Here's the DC law's definition of a personal trainer (which is pretty close to the definitions in other states), which actually passed in 2013 but after substantial efforts by Crossfit, us, and a few others, was mercifully repealed last year:
Even if someone is preparing for a competition, their trainer is "develop[ing] and implement[ing] an individualized approach to exercise, including . . . instruction in physical fitness and conditioning for an individual."
And even if you could develop a clever syllogism to explain why this law shouldn't apply to coaching for competition, how likely do you think it is that the state agency charged with enforcing the regulations will accept that argument? And how many people do you think are willing to bet a criminal record on it?
