Yeah, I was thinking the exact same thing about the Berardi information. Heck, the guy even used the same title!
And yeah, just watching that woman do squats on the ball side of that bosu made me cringe. I actually teach a "bosu" class at my gym (I "inherited" the class, and very rarely actually use the bosu; what the heck, it's money right? and I can actually teach people worthwhile exercises in the process) but I never have people do squats on the ball side of the bosu. "It's good for people recovering from a knee injury," yeah, that made me laugh and cry a little. More like "will cause you to get a knee injury".
What I will give this guy is he has a lot of energy (something which helps draw people to you), seems very enthusiastic about his work, knows how to get people's attention (using the free running group to get people's attention was pretty smart), and is getting his face and name out there.
Honestly, often times the trainers who end up making the most money and being the most successful aren't necessarily the best ones. More often it's the ones who are in people's faces and getting themselves out there.
