Although I love working out with my trainer, this gym is an unhealthy environment. It was 102 degrees yesterday and there was NO A/C on during the heat of the day. Instead, they opened the garage doors and blew in hot air. It was so hot that I had to end my workout early as I was getting lightheaded. This is a safety hazard and someone can get really hurt or get heat exhaustion if this continues. This has been going on all summer at all times of day - I have worked out at 11am, noon, 1pm, 3pm, and 4pm, and not one time has the A/C been on. Please use the A/C before someone gets really sick or hurt (or people quit coming to this gym).

I used to really enjoy this facility, but unfortunately, my experience has changed since the owner decided to stop using the air conditioning as a cost-saving measure. I waited several weeks hoping the situation would be addressed, but it has become clear that there is no intention to resolve the issue.

When I brought up the concern about how hot it was in the gym, the owner responded by saying it helps burn more calories—an answer that felt dismissive and unprofessional. I’ve also overheard many other guests expressing similar frustrations about the heat, yet nothing has changed.

Today, the temperature in the gym affected me to the point where I felt lightheaded and close to passing out. I honestly wouldn’t continue coming here if it weren’t for my trainer. I don’t feel comfortable recommending this gym in its current condition.

Update: 8/22/25 at the gym with no ac and it’s over 100 degrees outside.

Joined legion fitness for 6 months while living in Rancho Cucamonga. Best gym in the area hands down. All the necessary equipment you need. For my entire membership period I never had to wait for a single machine or piece of equipment! Also the cleanest gym I have ever been to.

I had the opportunity to do a free trial class with a trainer at this gym. Although I can not commit to the trainer’s schedule I absolutely loved the energy and aesthetics of this gym. However, what really sold me was the excellent customer service and approachable personality that Darin has. I called to check in before I went to train there with that other trainer and Darin was so friendly. I really appreciate him taking the time to help and his positive attitude. There’s a reason why this location has almost 5 stars. Thanks again Darin!

I highly recommend Legion if you're looking for a gym in the Rancho area! It's very clean, has all of the equipment you need, and is a lot less crowded than a commercial gym! And whether you're working out with a trainer or on your own, everyone is super friendly!

Darin is the friendliest owner. He gave me a tour of the facility and made me feel welcome. Gave me all the information I needed. No pressure for signing up. The equipment they have is top notch, especially if you like to deadlift or squat. Check them out with a free trial. It’s super easy to get set up. I would go after work and get a workout done so much faster than any commercial gym.

Man, I absolutely loved working out at Legion. I moved out of the area, which is why I am no longer a member there, but my six months of being a member were honestly the best gym experience I've had. Everyone, from the trainers to the owner and other gym goers, was super cool. Everyone in there had a goal and was there to achieve it. I highly recommend this facility to anyone.

Cannot say enough about this place!
Darren and Jen are welcoming and kind, and the facility is gorgeous.
It's spacious, well appointed, and has equipment and various different apparatus for every different form of physical movement and exercise.
Legion has top of the line bars including some specialty bars, calibrated metal plates, bumper plates, DL platforms, five racks, DBs and adjustable benches.
It's all you need, and it's a fantastic place to lift.

The Legion Fitness Facility  is my new home. Recently the bestest trainer I could have asked for took a leap of faith and we all jumped with her from the last place to the Legion Training Facility. It has so much opportunity for trainers and gym goers to share the space and the equipment and that makes a big difference. They have treated us all so well  Not to mention that it's all so nice and clean. I love the machines here. The quality of the machines has challenged me and it's making me stronger.  Samantha is a huge asset to have and with the right team and location we are all so happy and excited to be at the legion fitness facility.
Working out with Sam is literally like working out with the most perfect best friend. She cares about my health, my mental, my nutrition, and even my body aches. She is fully invested, she is watching every rep helping my form through the entire session and modifying things based on my bodies abilities. I asked her for beautiful defined legs and she has delivered in 4 months we have focused and targeted with intention. Not only am I wearing shorts all the time now, I also walk with so much confidence with my head held high and I carry myself differently. To Sam, aesthetics come as a plus, she truly wants to help people be in a better place holistically.
Sam always brings the most positive energy to our sessions and she makes me feel like more than a client. It's so motivating to have someone who truly believes in you and I think the most beautiful thing is that in return she has earned our respect and we, her clients, believe in her and we trust her and genuinely support her on her own journey. I wish I would have met her so much sooner. Sam is worth the time, just show up, she's got you.
