Maybe it's just me but I would want to know the certification level of my trainer. It's my responsibility to pick one that will benefit me. If I want to pick the said 18-year old with no cert then I must realize I'm picking potentially terrible advice that could lead to injury and no gains. I think the system is fine as it is, no government needed. It's the suckers who don't research trainers and will listen to anyone in a tank top that have the issues. That's what natural selection is for when it picks them off from the gym with an injury.
