Alfonso Avalos Jr.
Strength & Conditioning Coach

Being a competitive power-lifter, I have always sought different perspectives and beliefs in programming for competition. This led me down the rabbit hole of movement, speed, agility, periodization and injury prevention. My insulated world opened to new possibilities for not only training myself, but for competitive athletes, kids, seniors and their respective sports beyond that of what I know: squat, bench press, and deadlift. I continued my pursuit by volunteering with the San Jose Sharks during their Rookie Development Camps.

Alfonso is a  Certified Strength and Conditioning Specialist through the NSCA.
