Joe Byrd

Joe has had a love for fitness since grade school and as time went on he found himself in a routine of running for distance and biking a certain milage a day. He realized after running and biking for several years that he started to feel burned out on the repetitive routine, so he did research and discovered CrossFit. In 2009 he built a CrossFit gym in his barn and worked out by himself for a year and realized that Texarkana needed it's very own CrossFit box. In 2010 he decided to buy out a building in downtown Texarkana for his very own CrossFit gym. After 3 years he relocated to an area with more land space and built his own CrossFit box. Joe brought CrossFit to Texarkana because he wanted to help others strive for their fitness goals and be the best of themselves. He knew 1 hour in his box would bring people together and create an atmosphere that's hard to stay away from, due to the positive attitudes and encouragement that his coaches and others bring.

Dustin Moore

Dustin's brother was his motivation for trying CrossFit and at the time when he started 7 years ago his brother was a trainer and the programmer for CrossFit Texarkana. Dustin has been a trainer for over 5 years now and he just recently renewed his CF-L1 certification. His coaching style revolves mostly around relationships. Most importantly he wants his athletes to feel comfortable with him. While he does enjoy the competitive side of CrossFit, he gets way more out of someone who hits their weight loss goal or the person that gets off the medication they have been taken due to poor health choices. Dustin believes all you have to do is leave your ego outside of the box, listen to your trainers, put in the work and you can obtain your goals.

Three years later he recieved his L2, and in September 2018 became CrossFit Texarkana's first Certified L3 CrossFit Trainer. He also holds certifications in weightlifting and kettlebell instruction. He has a passion for helping others and truly has the heart of a teacher!
