C3 Athletics in Stamford is Connecticut’s Premier Fitness and Martial Arts Training Center. We have a competition quality ring, plenty of heavy bags and a wide array of specialty training apparatus. C3 Athletics is a facility where old school training and hard work meets modern training equipment and facilities, and offer instruction in Brazilian Jiu-Jitsu, Muay Thai, Boxing and Mixed Martial Arts.

We were established in January 2010. The people who put the gym together come from gyms all over the world and wanted to put the best of what they have experienced together in one place. Everyone at C3 Athletics are committed to providing top quality training in a clean, friendly and safe environment.
