Javier Villagomez, Certified Personal Trainer

Fitness Director

San Antonio Location

Hi, I’m Javier Villagomez. I have been enthusiastic about fitness and performance since high school. Basketball was my passion, but there was unfortunately no focus on sport-performance at my school. This motivated me to find ways of improving my performance, ultimately leading me to pursuing a career in fitness and health. I have over 10 years of experience in the fitness industry. I hold a Bachelor of Science in Kinesiology and Health from the University of Texas at Austin, with a specialization in strength and conditioning coaching. In addition, I am a Certified Personal Trainer through the American Council on Exercise. While in college, I had the opportunity to work with the UT Men’s Basketball team as an assistant strength and conditioning coach. I hold over 5 years of experience managing fitness facilities, as well as creating, implementing and directing fitness programs. My time in the industry has provided me the opportunity to coach a wide variety of small and large group fitness classes. I’ve also created summer programs for young athletes to enhance their sport-performance and weight-training. My overall goal is to motivate and improve the health and fitness of as many people as I can while educating them along the way.
