Truly the best gym in Southern California. Has everything you need from cardio machines, powerlifting equipment, bodybuilding equipment, and even functional strength stuff or plyometrics. The community here is awesome and the owner, Adam, is a great guy. Cannot recommend enough.

Decided to try out a newer, local gym and decided to try out hidden strength and this place didn't disappoint. The environment was instantly welcoming and this place had all the equipment I needed and more. Definitely one of the best in the area!
