Castro is a results-driven personal trainer specializing in strength training, functional fitness, youth athletic development, and longevity-focused programming. He helps everyone from young athletes chasing their next level to adults seeking sustainable, pain-free progress.

Originally from St. Croix, U.S. Virgin Islands, Castro grew up immersed in athletics, competing in soccer for eleven years and baseball for fifteen. That competitive background gave him a deep understanding of movement quality, speed, conditioning, and disciplined performance. These principles still shape his coaching today, especially his work with young athletes.

A United States Marine Corps veteran, Castro brings structure, accountability, and resilience to every training relationship. During his military service, including deployment to Iraq, he sustained knee and back injuries that required extensive rehabilitation. That experience reshaped how he approaches fitness. He now prioritizes intelligent progression, joint-friendly strength building, and long-term durability over short-term intensity.

Youth Athletics & Explosive Performance

Castro has a passion for developing young athletes. He builds the foundation that makes them faster, stronger, more explosive, and more resilient in their sport. His youth programming focuses on:

• Athleticism first:  coordination, balance, body control, and movement skills that carry over to any sport
• Speed and agility:  acceleration mechanics, change of direction, footwork, and reaction training
• Explosive power:  age-appropriate plyometrics, jumping and landing mechanics, medicine ball work, and kettlebell power development
• Strength foundations:  technique-first resistance training that progresses safely as athletes grow
• Injury prevention:  stronger joints, better landing and cutting mechanics, and resilience for the demands of a competitive season

Drawing on his own years in competitive soccer and baseball, Castro understands what young athletes face on the field. He coaches them with high standards, encouragement, and the mental toughness to compete with confidence.

Adults & Active Agers

Castro also works with adults who want meaningful, lasting results. His clients come to him to rebuild muscle after injury, improve body composition, enhance conditioning, or restore confidence. He is especially skilled at designing knee- and back-friendly programs that build strength safely while protecting the joints.

He emphasizes posture improvement and core stability, particularly for professionals dealing with the physical strain of long hours at a desk. His goal is to address imbalances before they become limitations, and to build strength that supports everyday life, recreation, and longevity.

He also works with active older adults and with individuals seeking osteoporosis-safe strength training that supports bone density and long-term independence.
