About Us

Steadfast Fitness & Performance is a personal training facility developed and facilitated by Isaiah Stanback (former Dallas Cowboy, Super Bowl XLVI Champion) and Jared Harrison (former University of North Texas Wide Receiver).

Understanding that people have varying fitness goals, our trainers will work with each client to provide a uniquely tailored fitness and nutritional program to promote a healthy lifestyle. Steadfast Fitness & Performance is also committed to the development and success of aspiring athletes, from little league to professionals. Steadfast Fitness & Performance will provide the training and mentorship required for athletes to reach their full potential.
