Zachary Welker has spent his life dedicated to fitness. He is a married father of 3, and a full time physical education teacher. A long time garage gym athlete, he has dabbled in all areas of training, from Olympic lifting, to power-lifting, and bodybuilding. He competed in Men's Physique for a year with a high level of success. In more recent years, he has competed in Brazilian Jiu Jitsu and searched for a training program to supplement the sport. Eventually the road led to finding Eo3, and jumping into the Hard to Kill track on Garage Gym Athlete. The level of overall strength and conditioning he achieved convinced him to commit and even become a Eo3 coach to help others.
