Knuckleup Fitness is an alternative fitness club that combines traditional gym services such as fitness kickboxing and indoor cycling with mixed martial arts classes.  Our location in Alpharetta, Georgia, offers classes in Kickboxing, Boxing, Brazilian Jiu-Jitsu, Mixed Martial Arts (MMA), Muay Thai and Personal Training. Knuckleup Fitness was founded in 1999 by Chris Stolzman.  With years of experience in the fitness and health industry, he wanted to create a gym and workout club in Atlanta that focuses on customer service and quality fitness and martial arts instruction. Whether you are a professional athlete, fighter, or someone that just want to workout in a fun, professional, and comfortable environment, Knuckleup is the answer!

Since 1999, the business has grown to become one of the largest privately and independently owned fitness and martial arts clubs in the Southeast.  With a total of six locations in metro-Atlanta and locations in Kitty Hawk, North Carolina and Lancaster, California; each club has experienced full-time instructors that will make sure your fitness and training needs are met.

Each club is equipped with a regulation sized boxing ring, more than 1,000 sq/ft of grappling mats, an assortment of between 50 to 100 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.

    I just wanted to give an update and let you know that our number has changed. (404) 339-KICK then pick the location desired.
    Also, we now have 8th degree Black Belt Master Ricardo Murgel teaching full time. So if you are looking to learn or compete in Brazilian Jiu Jitsu (BJJ) Submission Grappling, or MMA, we’re your place.

    Come in for a free week on me, tell them CJ sent you.

    Knuckle Up is heads above the two other health clubs I’ve been associated with. I recommend Knuckle Up to everyone. I’ve never been disappointed with the services. I am in the best shape and more healthy than ever. Give it a try. The monthly cost is very affordable and I’ve never regretted joining. The instructors are VERY knowledgeable with friendly staff and management always willing to help.
