Tanner grew up playing sports and was always interested in fitness. When he was 17, he started working with a personal trainer who would eventually introduce him to CrossFit. The workouts were like nothing he’d ever done before. "I spent tons of time in the gym learning everything I could about the methodology and application of CrossFit training."
Later, Tanner began working towards becoming a CrossFit coach. In 2013, he received his Level 1 certificate and opened Nuclear CrossFit the following year. Since then, he’s expanded his expertise to CrossFit Gymnastics, Mobility, Weightlifting, Competitors, L2, and USA weightlifting.
