Zach is Black Iron Nutrition's first male coach, but his success within Black Iron Nutrition has been absolutely because of Krissy Mae Cagney, and his wife, Laura. Zach has an extensive athletic career. Zach was a competitive swimmer for 16 years, competing for Brigham Young University in distance freestyle and butterfly events on scholarship. While at BYU, Zach was the team captain of the men’s swimming team, receiving recognition as a three-time NCAA Division I Academic All-American; five-time National Championship Competitor; two-time Open Water National Championship Competitor; and a NCAA Division I Championships Competitor. Zach was also recognized as the “Most Valuable Swimmer” and was voted by his teammates as the “Most Inspirational Swimmer.” Following his swimming career, Zach ran five marathons and three half marathons and coached USA Swimming and US Masters Swimming. Realizing he missed the team aspect of athletics, Zach began CrossFit in February 2013. Since that time, Zach has become at staple at local Nebraska competitions and has traveled across the country to compete at various competitions.

When Zach realized that spending hours at the gym, in the pool, or pounding the pavement wasn't enough, he constantly found himself frustrated with diets that would offer quick results, but not allow for sustainability. Finally becoming completely fed up with "fixes," he joined Black Iron Nutrition, along with Laura. The two were looking for a nutrition program that was possible to maintain in full-time professional jobs, while not completely giving up on foods they loved to eat. In one year, Zach and Laura lost around 75 pounds, completely overhauling their relationships with food, themselves, and each other, while also making giant strides in CrossFit.

Zach is an attorney in Lincoln, Nebraska licensed to practice law in five states. He understands how to handle high stress situations and daily difficulties and how to overcome the desire to "stress eat" or "emotionally binge." His relatable personality, ability to listen, and to provide beneficial feedback provide for a well-rounded coaching experience. Moreover, as Laura is a doctor of occupational therapy, he will regularly turn to her for insight on behalf of his clients to provide feedback for working professionals and couples trying to make sustainable, positive changes.

In his free time, Zach enjoys spending time with his rescue dog, Burpee, and rescue cat, George. He is the co-host of the podcast, "Lift Like Lawyers," and also records videos with Laura for his YouTube channel, "Anderson Macro Machines."
