I remember back when I first got serious about fitness. I poured over magazines and online content. After about a year I thought I pretty much knew it all. I knew how to eat clean. I knew the basic weightlifting exercises. I knew the basic supplements. Pop fitness. That's how I think of it now. Sure, I knew how to take someone who was in respectable shape, burn some fat, add some muscle, and walla... impressive progress pic.
I'm so much better educated today, but at the same time I have a deep appreciation for how much I don't know. They're still making new discoveries in basic human anatomy and how systems interact with each other. In fact, they're starting to realize the approach of viewing the body as a set of independent systems is flawed. Everything is connected.
As a fitness professional, you have to be comfortable with uncertainty. Everybody has a unique biology. What works for one person may not work for another. I am humbled by the opportunity to help others improve their health. I do so by living in the space of a question.
