Mitch Luallen

Certifications: CrossFit Level 1

Mitch practically grew up on the ice with a stick in his hands. But during his 14 years of ice hockey with the Ohio AAA Blue Jackets, there are very few sports or athletic endeavors he didn’t try during the off-season: from rock climbing to track & field, from soccer to coaching younger hockey players and everything in between. Once his ice hockey career ended, CrossFit was just a natural unknown to sink his teeth into. He instantly fell in love with the methodology. Mitch joined CrossFit IPA after graduating from Ohio State University. Through his years of youth ice hockey, he was exposed to nearly every type of sport-specific and athletic training, and even began writing his own programs in high school. Mitch has a breadth of experience to draw from to help anyone achieve their goals.
