C2 Training · Est. 2013 · Cornelius, NC · CSD Family Since 2011
C2 Training is proud to sponsor Spartans Athletic Club, and for our family, this one is personal. We are a CSD family through and through. Kristin was on the original staff when the high school first opened its doors. Our oldest, Rush, went K through 12 at CSD, graduated in 2026, and is headed to Montreat to play college soccer. Jett is a rising 7th grader who has been a Spartan since kindergarten plays lacrosse and football for CSD, and Cruz joins the party in the fall of 2027. We are not sponsoring this community from the outside. We live in it, and supporting the teams our kids and your kids play for is part of why C2 exists.
You may have known us as CrossFit Cornelius. Same owners, same objective, and now with a name that matches everything we have grown into: C2 Training. From our two building campus in Old Town Cornelius, every class we run is led by a credentialed movement coach, and our facility includes on site physical therapy, massage therapy, and performance nutrition guided by a registered dietitian. We train for the long game: strength, durability, and health that lasts for decades, not just for a season. You will still see our original name on our email for a while as we make the switch, so do not be surprised when a reply comes from a crossfitcornelius.com address. Same people on the other end.
For young athletes, our C2 Athlete program offers sport specific small group training and personal coaching in training blocks that align with your athlete's season. Programming is built for developing bodies, not scaled down adult workouts, and focuses on the speed, strength, and durability that transfer to every field and court.
For parents, the variety is the point. CrossFit Group Class delivers strength and conditioning in one coached hour. HybridFit gives you the same training effect without the technical barbell work, and it is many of our members' favorite starting point. Lift is a pure strength class, because strength is for everybody. Engine is pure conditioning for heart health and endurance. Strength Lab is our dedicated strength program for women navigating perimenopause and menopause, built around science most programming ignores. Whatever your training background, or lack of one, there is a coached class that fits, and every format runs on the same programming so they work together. Many CSD families train with us while their athletes do the same.
Come see us at 19721 Smith Circle in Cornelius, or book a time to talk with a coach and we will help you or your athlete find the right starting point.
Onward and Upward
Mike & Kristin Ratnofsky
