About The Ground Zero STrength GYm and Community

How It All Started

I started Ground Zero Strength in November 2021 with one mission. Bring real strength training to Twin Falls. After years of coaching in box gyms and athletic performance facilities, I wanted to create a place where people could train seriously without the distractions, gimmicks, or intimidation of a typical gym.

What began as a small private facility has grown into a community of lifters of all ages. 55+ adults staying strong and independent, women gaining confidence under the bar, athletes building a competitive edge, and everyday people who just want to look, feel, and perform better.

I built Ground Zero Strength to be more than a gym—it’s a place where real coaching, proven programming, and a supportive environment come together to raise the standard for what strength training should be.
