I am not a fitness buff. No amount of ZUMBA! will ever make me a fitness buff. No amount of trailing my marathon-running sister on a bike will ever make me a fitness buff. And taking a look at my cooking habits guarantees I never will be.
Ryan Andrews, on the other hand, has an MBA in fitness. My kind of MBA and an actual master's degree. He was a nationally-ranked body builder for five years and has more health/nutrition/exercise certifications than I have red high heels.
