In looking at getting certified. There is a big difference in the certifications. Believe it or not a Coach is below a Trainer.
A Coach is general knowledge. A Trainer is way more in depth and more certified. Certified Coach is like a substitute teacher, Certified Trainer is like a teacher and Certified Master Trainer is the principle.
Anyone not certified and claims to be is in for some posable law suites.
The advantage to getting certified as a Coach is to show you past tests showing you have the general knowledge to pass on, and cover your butt.
But yes I agree when they get certified they should personally and physically practice what they preach. This will put more stock in what they know. They should have a track record to back up there claims to knowledge.
I hate being in the gym and seeing trainers 40 lbs over weight pushing people in better shape than them. Isn't this the POT calling the Kettle black?
