THE TEAM

ANTONIO BURGOS
HEAD OF ATHELETE DEVELOPMENT
Antonio has spent years coaching clients from all walks of life, and that range shows in how he trains. Whether he's working with a student athlete chasing a competitive edge, or someone just starting their fitness journey, he adjusts his approach without ever cutting corners on the fundamentals.
​
His work with student athletes carries him through both in-season and off-season training, where the goals shift constantly: building strength without disrupting performance, managing fatigue, and keeping athletes healthy through a long competitive calendar. That same attention to detail carries into his work with everyday clients, where the goal is often less about the scoreboard and more about building something sustainable.
​
Outside the gym, Antonio is a husband, a father, and a dance teacher, a background that shapes how he thinks about movement, discipline, and body awareness in ways a typical strength coach might miss. It's part of what makes his coaching feel complete: not just sets and reps, but a real understanding of how the body moves and what it takes to keep showing up for it.
