Crossfit Subzero | Isaias Starkman

Isaias Starkman

Isaias AKA Mufasa, originally from Perth Ontario came to Thunder Bay to enroll in the Honours Bachelor of Kinesiology Program at Lakehead University. He is currently coaching part-time here at Crossfit Subzero while finishing his last year of his undergraduate degree. Coming from a small town, where the opportunities that promoted fitness were limited, Isaias found it difficult to find an outlet where he could thrive as an athlete. In 2013 a friend showed Isaias some highlights from the 2012 Crossfit Games. He was intrigued. Then in 2014 Isaias joined an affiliate, where he realized what real training and community felt like. He was hooked.
