our history

written by: mario barajas

Crossfit San Antonio opened in 2007.   It was THE very first crossfit gym to open in San Antonio... hence the name. It's original location was off of Mainland Drive, but in 2014 the gym moved to its current spot on Glen Ridge. On November 1 of 2015 I became the owner of this amazing gym.


Why do I do it? The thing that drives me the most is helping people achieve things that they never in their life thought they could do. Showing them that had work, dedication, positive attitudes, and a do-not-quit attitude will not only change your body, but the way you look at life. Crossfit does not only make you physically strong, but makes you mentally strong which goes a lot further then physical strength. The idea and feeling of changing someones life is so rewarding! We show them that anything is possible. The more people that come up and thank me, or jump up for joy and dance because they did there first pull up, or ran there first mile without stopping, fuels my fire.


Crossfit San Antonio is a place where no matter the age, physical condition, experience level, or sport background you have, you will ALWAYS be welcome and get the best workout while maintaining good form and safety. We have the best community where everyone is welcoming and friendly. Our community is what makes us great. That's why we've been around for 10 years.

We are a drama free gym. Our experienced coaches will motivate you and give you nothing but the best. We are not just a gym, we are a family. I care about every one of our athletes because we are not in the gym business, we're in the people business. Our programs will challenge you day in and day out.  So if you’re looking for a gym where you will be greeted with a smile, no matter what age, or condition you’re in, whether you’re goal is to make it to the Crossfit Games, or be able to keep up with your kids we are the gym for you!

As a San Antonio native I have been crossfitting on and off since 2011. In January of 2018, I realized that I needed to better myself physically and mentally so I committed myself to crossfit and weightlifting. Crossfit has helped kickstart the process of  getting closer to my goals of physical and mental well being.


The camaraderie within the Crossfit community, especially at Crossfit San Antonio, has helped me replace something I felt was missing after leaving the United States Marine Corps. I enjoy coaching and have a thirst for knowledge to not only try and better myself, but also the athletes around me.

I was introduced to Crossfit in 2009 while serving on active duty in the US Navy and have been involved with the methodology ever since. As a native of San Antonio and alumni of UTSA, I returned to the area recently, joined the CFSA staff, and have enjoyed every minute. Coaching our current, future and tenured members has truly grown into a passion. I am committed to helping each of our athletes reach their fitness goals, whether it’s losing weight, gaining strength and flexibility, rehabbing an injury, improving technique, preparing for a career in military/ police/ fire or just getting healthier. My experience with various sports, weightlifting and athletics combined with a special operations military background, allows me to bring a unique perspective to the box.

Stephanie was first introduced to Crossfit back in 2006 while working out at her college gym and periodically did Crossfit until 2014, when she fully committed after realizing how impactful it is to overall fitness. She is currently active duty military, and has found Crossfit to be essential in keeping her physically and mentally ready for anything the army has in store. Stephanie is incredibly passionate and dedicated to Crossfit because of the challenges and achievements that it offers. She hopes to help others achieve goals they didn't think possible.

Jen hails from Minneapolis, MN and enlisted in the U.S. Air Force in 2016. Jen comes to us from a martial arts background as a two time national grand champion in Tae Kwon Do in both sparring and breaking. She was introduced to Crossfit in 2017 and instantly fell in love. Jen is a hobbyist and busy body and loves the never-ending activities that Crossfit provides.  Jen's passion is to do her personal best everyday and motivate others to reach their maximum potential.

Janice Hernandez spent years trying different fitness regiments, but it was until CrossFit that she found a sport where she was constantly challenged and saw long lasting results. Janice was introduced to CrossFit San Antonio in 2012 and is one of our longest standing members. With her busy lifestyle in Public Relations, she appreciates how CrossFit’s programming fits into her daily routine. Her favorite part of the sport is that it’s continuously evolving and that you are always forced to learn something new. She also loves that the CFSA has a family/community environment with everyone passionate about the same goal. Janice enjoys pushing her athletes outside their comfort zone. Her favorite part of coaching is watching the look on an athletes face when they learn something new, whether it be their first pull up or muscle up.

I have had a passion for health and fitness since high school. However, once I found crossfit I became even more passionate about fitness. I started crossfit right after I graduated UTSA in 2017 with my Bachelor's in biology. I fell on love with crossfit immediatelt! It not only challenges you each and every workout but has a great community. Outside of crossfit, I am currently pursuing a career in the medical field as a nurse and hope to some day use my skills to assist in trauma and in first response teams.
