About KnuckleUp

KnuckleUp Fitness was founded in 1999 by Chris Stolzman. With years of experience in the fitness and health industry, he created a gym and workout club in Atlanta that focused on customer service, quality fitness and martial arts instruction. Whether you are a professional athlete, fighter, or someone just wanting to workout, KnuckleUp Fitness provides a fun, professional, and comfortable environment to train.

Over the last 14 years, the business has grown to become one of the largest private and independently owned martial arts clubs in the Southeast. With multiple locations, each club is equipped with full-time instructors to ensure your fitness and training needs are met.

Each club is equipped with a regulation-size boxing ring, more than 1,000 sq/ft of grappling mats, and dozens of Muay Thai and boxing heavy bags, speed bags, double end balls, and uppercut bags.  We also provide state-of-the-art free weights and weight machines from Life Fitness, Hammer Strength Nautilus, Stairmaster, Precor, and more.
