How We Started

X3 Sports was founded in 2007 and started off as a small, single location fitness facility in Marietta, Georgia focusing on kickboxing, boxing, and mixed martial arts classes. When the first location opened, all that existed was minimal equipment but a passion that got people excited that they could achieve their goals here. Like many of our members, our goals seemed unreachable but through hard work, dedication and blood, sweat & tears, X3 Sports has become one of the premiere training centers in Georgia! Now with 3 locations: Inman Park Atlanta, Marietta and West Midtown Atlanta and our newest location in East Cobb.
