The people who coach you

JC Rocha is the founder and owner of District Flex Dominion and a Nationally Board-Certified Athletic Trainer with a background in Sports Medicine. A graduate of the University of the Incarnate Word, JC has built his career around understanding the human body, improving movement, developing strength, and helping people continue doing the things they love.

Throughout his career, JC has worked with individuals across nearly every stage of life — from 5-year-old youth athletes to adults 87 years of age. His professional experience spans middle school, high school, collegiate, professional athletics, and the general fitness population, giving him a unique perspective on how training needs change throughout a person's lifetime.

JC founded District Flex with one central purpose: longevity.

His philosophy is simple: Train the body you have today.

Training shouldn't be about trying to move like you did 20 years ago or chasing an unrealistic version of who you think you should become. It should begin with understanding your body right now — its strengths, limitations, movement patterns, and goals — and developing it from there.

At District Flex, the goal is to help people train smarter, move better, build strength, improve mobility, reduce unnecessary pain, and create a body capable of supporting the life they want to live.

Whether you're a young athlete developing your foundation, an adult trying to stay strong and active, or an older adult focused on maintaining independence and quality of life, the mission remains the same:

Build what you have. Protect what you have. Keep moving for life.

Known for his hands-on approach and commitment to individualized care, Marcos takes the time to understand each client's unique goals and challenges, crafting treatment and training plans that produce lasting results. His decade-and-a-half in the field has given him deep expertise in injury prevention, rehabilitation, and performance optimization.

Whether guiding a client through post-surgical recovery or coaching an athlete toward peak performance, Marcos Hernandez brings the same level of professionalism, knowledge, and genuine care to every session.

I believe feeling your best starts with moving your best. As a personal trainer, recovery specialist, and bodyworker, I am passionate about helping people become stronger, move with less restriction, and feel more confident in their bodies.

Whether your goal is building strength, improving mobility and flexibility, recovering from everyday aches and tension, or simply feeling better day to day, I take a personalized approach tailored to you and your goals.

What I enjoy most is helping people make progress they can actually feel, and creating an environment where you feel comfortable, supported, and confident every step of the way.

My goal is simple: to help you move better, feel better, and become the strongest version of yourself.
