Our story.
Gym in Spring Hill & Columbia, TN
CrossFit Thunderhead was founded by Zack and Brittany Pringle in 2020 because Spring Hill needed a gym where people actually get coached, not just handed a membership card. Today that’s two gyms across Spring Hill and Columbia, built for real people, whether you’re stepping into a gym for the first time or you’ve been training for years.
Meet your coaches at CrossFit Thunderhead
Our coaches invest in people, not just programs. From your first session, they’re learning how you move, what drives you, and where you want to get to, then coaching you accordingly, every single time. Across both gyms, you’ll find the same standard: coaches who know your name and care about your progress.
Born and raised in Northern California – Zack was always active & athletic growing up. Ironically, he never liked to work out, because he was always the skinny, weak kid. However in college Zack and Brittany were convinced to try CrossFit, and now for the better part of two decades CrossFit has been a central component of their lives. Operating a CrossFit gym is dream come true, and there is nothing in the world he would rather do than coach the Thunderhead Fam.

Our Mission
How CrossFit Thunderhead started
After more than a decade of coaching and living the CrossFit lifestyle, Zack and Brittany had seen firsthand how it changes lives. Parents keeping up with their kids. Grandparents regaining their independence. Busy professionals discovering they could prioritize their health without sacrificing everything else.
They also believed CrossFit could be delivered differently. Too many people think it’s only for elite athletes, or that they need to get in shape before they can walk through the door. Thunderhead was built to prove the opposite: coaching, programming, and community designed to make world-class fitness approachable, encouraging, and genuinely fun for everyone, regardless of age, experience, or fitness level.
What started in Spring Hill in 2020 has grown into two gyms and a team of twelve coaches serving Spring Hill, Columbia, and the surrounding areas. The mission hasn’t changed: help ordinary people live better through fitness. If we make the process easy and enjoyable, the results take care of themselves.
