member reviews

This neighborhood gym was exactly what I was looking for. I needed personal training and a local gym to squeeze 3-4 workouts in weekly. Bernie the owner is very knowledgeable and personable, and he quickly got me in a routine I can actually do and build upon. I appreciate a smaller gym as you really get a custom experience. I highly recommend! — Katie, Orange County (August 2025)

Great place to workout, amazing equipment. Family atmosphere and everyone is very welcoming. Felt very comfortable working out at Fitness Authority. — Connie, Mira Loma (August 2025)

Bernie, the owner has been there for many years and has many loyal clients. I know him personally and he deserves every bit of a five star review. — Tony, Tustin (June 2025)

Extremely lucky to discover Fitness Authority during Covid! I was made to feel welcome immediately. Whether you are trying to figure out how to exercise or you know your way around workout equipment, you will enjoy the atmosphere. The staff will meet you where you are... that's the beauty of this place! Coming from a large corporate gym environment, it's nice to get the warm family feel I got from Bernie, Fred and Karen alike.

I highly recommend you check it out for yourself :) — Gab, Orange County (June 2021)

I have trained at fitness authority for over 6 years. I think of the people there like family. It is a well run, clean and has excellent trainers offering flexible hours to accommodate people's busy schedules. It's a small, family owned business with easy parking which is important to me. Bernie takes great pride in his facility and the personal needs of his clients and trainers.

Fitness Authority has some of the finest and most dedicated trainers in Newport Beach. I love this private gym. They also have a beautiful welcoming committee, the family dog. Five stars. — Nancy, Newport Beach (May 2019)
