A strength coach who became a chiropractor.

I was a hurdler and sprinter in high school, allergic to anything over 400 metres. Through university I lifted and kept bulking. I thought I was healthy because I was exercising.

During chiropractic school I developed health problems nobody could explain. Six months and a lot of money later, the scare was over, but it changed me. Exercising and being healthy are not the same thing, and nobody in the fitness world had told me the difference.

Basketball was the first real cardio I'd done in years, and I started feeling good again. Back in Canada, broke and waiting to write my licensing exams, I joined a run club because it was the cheapest way to keep moving. I felt even better. Then I started cycling to work and fell in love with that too, and picked up jiu-jitsu and judo. Strength and endurance together turned out to be worth far more than either one alone.
