Sure, I insist on practicing what I preach and always have. Also only keep certifications I enjoy using/teaching. It indeed makes for a deeper understanding of what people may feel and experience but all athletes are a bit different. Does it lend credibility to my suggestions? Sometimes. (sorry to say this) After being in Fitness for many years, I find often the best looking or most buff looking folks will have ignorant clients drawn to them just because of looks. But later, some of these clients, once they have a better understanding of what comprises a “good” trainer, will look for someone with more experience and training.
