Erwin started coaching after discovering CrossFit in 2005 at UC Santa Cruz. He began coaching at Nela Athletics in 2012, then moved to Shanghai in 2013 to help build the early CrossFit community in China. After 10 years coaching and scaling affiliates there, he’s back at Nela Athletics to bring his experience to the Nela community. His mission is to educate and inspire people to build a long-term relationship with fitness because health is about more than aesthetics; it improves everything else in life. Outside the gym, Erwin collects baseball cards, especially Mookie Betts and Dodger greats.
