She also worked with her high school girls soccer team whom she played with for all in high school.

Head Trainer
Travon Barber
Travon’s fitness journey began with his love for sports, excelling in football, basketball, and track. In college, he combined his passion for movement and curiosity about the mind by studying Psychology before switching to Kinesiology to focus on how the body works. Since graduating from SFASU in 2019, Travon has brought his expertise and high energy to bootcamps, one-on-one training, small groups, kickboxing, and partner workouts.
His motto, “Get Right by Any Means!” reflects his commitment to helping clients crush their goals. A Kansas City native and proud Chiefs fan, Travon’s enthusiasm is contagious both in and out of the gym. He also dabbles in standup comedy, so don’t hesitate to share your best jokes during a session! When you train with Travon, you’ll feel unstoppable—just like the momentum at Elevate Fitness, lifting you to new weights!
Head Trainer
Ruben Martinez
Ruben brings a unique blend of athletic grit, real-life resilience, and deep passion for performance training to the Elevate Fitness team. A lifelong athlete, Ruben grew up immersed in sports—competing in football, track, and cross country. His early dreams of going pro were abruptly redirected when a serious health challenge during his first semester of college forced him to rebuild from the ground up. That experience didn’t slow him down—it ignited a fire. Ruben dove headfirst into understanding the science of movement, recovery, and mental toughness. Today, he’s a certified Performance Enhancement Specialist through ISSA, equipped with CPR and AED credentials, and is known for his ability to connect with youth and adult athletes alike.
Whether he's coaching young competitors chasing scholarships or adults looking to move better and feel stronger, Ruben brings intensity, purpose, and heart to every session. His mission is simple but powerful: to help others unlock their potential and train not just harder—but smarter. If you're ready to work with someone who’s been in the trenches and come out stronger, Ruben is your coach.
