By popular demand, Katie Hogan becomes our first female guest on the PowerCast. Good thing she can hold her own when Mark tries to get to the bottom of her famous short shorts! Katie is a CrossFit competitor, a elite raw powerlifter and has competed in Olympic weightlifting. We talk training, nutrition and the ups and downs of being a coach. Katie also gives us her take on the mental toughness needed for grueling SealFit course she recently completed. (Yes, she's probably tougher than you. We're pretty sure she's tough than us.) Katie recently appeared as a trainer on "The Biggest Loser." She's also a Crossfit Level 1 coach, a USAW Level 1 Sports Performance coach, and an ACSM Certified Personal Trainer.
