It used to be that a personal trainer was the big guy in the gym — Joe Bodybuilder — who had been there for years and decided to make money trying to help people look like him. While that scenario may still play out in some places, personal training as a whole has evolved, and continues to evolve, into a more reputable field. Most personal trainers are now considered to be health and wellness professionals. They go by many titles, including Fitness Consultant, Strength and Conditioning Specialist, Fitness Instructor, and Personal Fitness Coach.
