Trevor Kimm is the 96kg USA weightlifting national champion.  He's also a clinician and overall really smart dude.  So we thought he'd be a good guy to sit down with and chat about the rash of positive drug tests in CrossFit so far this season.

Topics we cover in this conversation:

- What does drug testing look like.

- What is USADA and what is Drug Free Sport?

- What are the drugs that people are commonly using in fitness?  What do they do and how long do they stay in your body?

- What does "NSF Certified for Sport" mean when you bud a supplement?

- Why are more and more people testing positive?
