Custom Fitness is a functional fitness facility offering consumers a wide variety of professional health and wellness services.

We provide consumers a variety of services including person training, team and sport-specific trying, rehabilitate services provided by our in-house physical therapist, corporate wellness, nutritional advice and CrosssFit, a principal strength and conditioning program that is broad, general and all-inclusive, designed for universal scalability.


Paul and Ryan Claros were born and raised in Guam and founded Custom Fitness in 2012. They have been active members of the Guam Athletic community for the past 15 years, both as athletes and coaches, and saw a gap that existed between appropriate preparation, proper execution and correct programming for daily sports performance.

The lack of integration of all functional components validates the need for Custom FitnessCustom Fitness in and of itself is a multidisciplinary approach to health, fitness and nutrition.  With the integration of scientific programming and collaboration of a health team, Custom Fitness is designed to fill the gaps which people often are not aware of or knowledgeable about. The addition of the rehabilitative component truly makes Custom Fitness all-inclusive for health and wellness needs.   Succinctly stated, “appropriate preparation + proper execution = advanced performance”.
