CROSSFIT AMMO is unlike any box you have ever walked into. Although our box is the cleanest box in America, full of the best equipment and most experienced coaches, it’s the people that fill this box every day that make this box the best box in the world! Starting in a garage in the middle of 2012, CrossFit AMMO emerged. Once people were flooding out of the garage doors, CrossFit Ammo moved to 1201 E. Main Street in 2013 with a total of 56 members. Today AMMO is made up of over 150 dedicated members… we are moms, dads, grandparents, teachers, real-estate agents, and businessmen with the common goal of staying fit and having fun while doing it!

CrossFit Ammo is a 4,000 sq. ft. building.  When you walk through the doors, you will see unique paintings, quotes, flags, and stickers that represent who we are. We have a pull-up rig located in the center of the box that we use just about every day, two ropes hung from the ceiling, and barbells and plates fill our walls. Manly people ask, “Where are all the machines?” Our response is always the same… "WE ARE THE MACHINES.” CrossFit Ammo has a kids room for kiddos to hang out in while their parents get in a good workout. The kid's room has a couch, books, chalk boards, and a tv. We love our AMMO KIDS ROOM!

CrossFit Ammo also has a shower for their member's convenience. You may hear this area called the AMMO Spa! Help yourself to lotions, shampoo, conditioner, and soap. If you have to head to work right after a workout, no worries…you can shower here! COME CHECK OUT THE BEST GYM IN ALLEN, TX….CROSSFIT AMMO!!!

He played college basketball at Oklahoma Baptist University and graduated with a Bachelor's degree in Psychology from Texas Tech. After graduating, he received his Personal Training license from Coopers Clinic and pursued a career in the fitness industry. CrossFit became a part of my life in 2011 and I was and still am drawn to the fact that there is a constant challenge and a constant drive to improve. In CrossFit you will always be faced with a new challenge, whether it's a movement, a 

1RM, or the latest Open WOD, regardless you must continue to embrace the challenges by constantly improving your abilities. You can not be a one-sided athlete in CrossFit but must be balanced in weightlifting, gymnastics, metabolic conditioning, mobility, and flexibility. If you are lacking in one area then you will be exposed. As a coach, it is my job to show the correct progressions that will get each member to their desired goal, and it’s what motivates me to stay current in the research and to evolve with CrossFit. I love movement, and I believe that establishing a solid foundation with the understanding of correct movement patterns will allow any individual to constantly progress and reach their fitness goals.
