I've been in and around the fitness industry for my entire life -- as an athlete, as a coach, as a lecturer. I know that different people learn things and respond to things in different ways. Some people are more apprehensive than others; they need to be steadily pushed to achieve their goals. Some people are more analytical; they need to know the exercise science behind what they're doing -- right down to the cellular level -- before they'll try anything new.
