All Gold Core groups are capped at 6 people maximum. This isn't a policy — it's the entire model. Small groups mean every rep gets coached, every client gets corrected, and no one gets lost in the crowd. It's the quality of private training at the value of a group class.

Gold Core serves two main populations: adults (any fitness level) looking for real strength, conditioning, and mobility results without wasting time in a big-box gym; and youth athletes ages 12+ who want to improve their speed, power, and athletic performance. Golfers of all handicap levels also train here year-round.

Gold Core is at 3916 Sepulveda Blvd, Torrance, CA 90505 in the heart of the South Bay. We serve clients from Torrance, Redondo Beach, Palos Verdes, Manhattan Beach, Hermosa Beach, Rolling Hills, and Lomita.
