    I've been a member at this Chuze Fitness location since they first opened in Rancho Cucamonga, and…read moreoverall I really do like the gym. That's also why some of the changes over the years have been disappointing. When this location originally opened, one of the BIG reasons I signed up was the 24-hour access. Obviously COVID changed everything for a while, but years later, I'm disappointed that the gym never returned to the hours it had when I originally became a member. With the more limited hours, it also feels like everyone is trying to squeeze their workouts into the same windows, and the gym can get ridiculously crowded. I understand gyms need memberships to operate, but at some point I think there needs to be more consideration for capacity. There are times when it feels like there are simply too many memberships for the amount of equipment and space available. It can make getting a normal workout in frustrating. Cleanliness is hit or miss. The employees are okay overall, although the friendliness at the front desk can be inconsistent. Sometimes you'll get a hello or goodbye when walking in and out, other times not so much. There are still plenty of things I genuinely enjoy here. I LOVE having access to the sauna and steam room, and when the gym isn't packed, I really enjoy working out here. I've stuck with this location since the beginning because I like Chuze. I just wish some of what made this gym so great when it first opened--especially the extended hours--would come back. With better hours and some attention to overcrowding, this could easily be one of my favorite gyms again.

    Absolutely terrible location and corporate culture…read more Do not get a membership here. If I could give this place zero stars, I would. Chuze Fitness in Rancho Cucamonga is run by a terrible corporation that does not care about its community or its members. The management at this specific location went out of their way to falsely accuse me of violating a policy that I didn't break. Instead of acting professionally, communicating clearly, or actually investigating, they treated a paying member with total disrespect and hostility. You go to a gym to work out and clear your head, not to deal with corporate headaches, staff power trips, and baseless accusations. The entire vibe here is ruined by how poorly managed it is. Save your time, your money, and your peace of mind--go to any other gym in the area where they actually treat people fairly. Avoid this place at all costs! DO NOT GO HERE TERRIBLE STAFF & DISGUSTING ENVIRONMENT. VERY UNCLEAN.

It's true that people are more respectful at this gym because when I walked in everything was clean and everyone was wiping things down and re-racking their weights. It makes for such a better lifting experience when everyone respects the equipment and facility. You sign up on an app and you beep in via a bluetooth system which was convenient for my early morning lift. I even got to meet the owner Ian, and he was cool and helped me get a day pass fast which was great! I intend to come back here! 10/10.

    Terrible experience at this neglected gym!…read more I joined this gym on the beginning of this month (April ) and got my membership canceled by the owner 12 days later which I only used the facility 3 days to workout. I have multiple gym memberships from commercial to private gyms and this was a first. I always clean and unload the machines after each use and this day was not a different day. I was approached by the manager of the gym which is the owners brother in a disrespectful way, telling me to rerack the weights from previous machine which I clearly unload the machine, but the gym does lack on weights stations to unload to it, so I left on the side of the machine organized which he told me to put where I got them from, which was from walking around the gym grabbing from machine to machine and I told him that it doesn't make any sense when they lack on stations to drop the weights on it. Although I went back and did what he said. I pay to go there not to work there. 2 minutes later as you see the screenshot, the owner Mario texted me saying it is courtesy but them is rules which is not on the contract anyway. So they canceled my membership when I didn't even left the machines loaded or weights on the floor. Unfortunately this was a act of discrimination from the manager to me as a person as there was one other dude earlier time leaving all weights on the machines and nothing was said. I was going to cancel the membership on Friday due to this gym been neglected for long time. Machines are mostly ripped off , tapped or some broken. Machines are on top of each others or next to the walls with wires or ladders next to or impossible to load them, so many hazards. Bathrooms are dirty and trash all over the place most the time and barely anyone at the gym. Men's locker room is a mini one dirty with broken toilet and main door doesn't even fully close. What you see on IG are all filters and angles, they clearly misleading people, I joined online on their website from social media, as if I add gone see it before in person I wouldn't ever join it.

    Honestly best gym I've ever been a member of, by far the best machines, you can tell the owner…read moreknows his stuff. The layout is a little weird and can feel overcrowded at times but I feel the negative comments on that are a little over blown. The music can also be too loud on some days, to the point where you can't even hear your own music with headphones on but I do appreciate the fact that customers are allowed access to the aux. Another gripe I had, which was a big one considering how much monthly you were paying was that several machines would be out of order on a consistent basis especially in the cardio department, as well as a urinal in the men's restroom. It's been a few months since the last time I was there, so I don't know if that's been resolved by now or not. Owner is a really cool guy and was very responsive to all my inquiries and messages. Main reason I'm not going here anymore is because of a one-off, petty dispute my friend had that was both initiated and escalated by a trainer working there but outside of that, it's arguably the best gym in the ie.

    This gym is completely unrecognizable from what it used to be. What once felt like a true community…read morenow feels like a corporate rebrand that forgot the people who built it. The culture has shifted away from the diverse, welcoming vibe that reflected Ontario and into a loud, performative, hyper- bro, heavy metal/rock atmosphere. It's not technically "bro only," but if you're not part of that energy, you're effectively invisible. When new ownership came in, they fired the long-time employees who made the gym feel like home, and since then the environment has become uncomfortable and oddly transactional. The vibe now feels performative rather than genuine. The trainers are loud for the sake of being loud, hyped to an almost cracked-out level that feels disingenuous instead of motivating. The favoritism is impossible to miss. I'm here weekly, and Miguel, the owner, has never once acknowledged my existence. No hello. No nod. No eye contact. Meanwhile, he's fist-bumping the men on either side of me like it's a frat boy reunion. Every. Single. Time. As a woman, it's hard not to see the pattern. He'll happily engage with the conventionally attractive women, but if you're just a normal person trying to work out, you're ignored. If you're not ripped, or radiating alpha energy, you're background noise. It's giving used car salesman confidence with a dash of outdated male chauvinism.. A gym should empower people and make them feel welcome, not dismissed or overlooked. It's genuinely disappointing to watch a once inclusive space push away the very community that made it successful in the first place. P.s. please diversify the music again! We need some reggaton, rap, and EDM... It's missing some Ontario culture.

The workout itself looked intense and pushed the class to the edge. No one was coasting, and the pace stayed high the entire time. Autumn stayed locked in with her group, motivating and pushing them without letting the energy drop. You could see how much the class fed off her. Her motivation felt real, not forced, and it showed in the effort everyone was giving. Even just watching from the side, it was obvious her energy is unmatched. She's the kind of coach that makes people push harder and stay engaged.

You are going to spend more money and have more issues at another gym. Trust. The pregnant manager goes around and sanitizes and vacuums--that's not going to happen at other gyms. Staff is super nice and friendly. The gym does run its A/C. Thank you for not being cheap because I don't know who wants to workout in a hot and stinky gym. Members keep to themselves--reasons why I have left other gyms. I'm giving it a 5 (but really a 4.5). I wish they had more/better equipment. They really need machines similar to Gold's Gym. Gold's has more leg machines but their stuff is always broken lol. Fit 19 has some repetitive and hardly-used equipment. I love that you can go into the studio and access all the kettlebells/weights/bars/mats This is usually restricted in other gyms. They often do not let you use weights in the studios at other places. The turf area is nice as well and is always kept clean and organized. People don't leave weights all around the gym--like at other gyms. The equipment is rarely broken like at other gyms with higher price points. You'll be lucky if LA Fitness' cardio machines are working. The spin bike room is so nice compared to other gyms as well. There's a lot more bikes compared to other spin rooms. All in all, you get what you pay for and in my opinion, I'm getting more than what I pay for--$10 a month. It's not a high-fees micro-managed establishment like most lower priced gyms.

Obviously, I refused to pay and decided to leave instead. The employee who assisted me wasn't terribly rude, but they were very indifferent and had zero customer service skills. Also, after reading other reviews about people having issues with unfair cancellation fees, I'm honestly glad things turned out this way because it saved me from making the mistake of signing up here. I do not recommend this place at all.

After…read morelosing over 40 pounds, I knew it was time to focus on getting stronger, but I was honestly intimidated. I didn't know how to use the equipment or even where to begin. One day, I noticed Fit Nation had opened close to my home, so I decided to stop by and ask about memberships. As soon as I walked in, I was greeted by Suli, one of the owners. She welcomed me with a warm smile and immediately made me feel comfortable. When I shared that I had never been to a gym and was nervous because I didn't know how to use the equipment, she reassured me that she would personally show me around and explain how everything worked. She took the time to walk me through the equipment without ever making me feel embarrassed or overwhelmed. Her kindness, patience, and genuine encouragement gave me the confidence to sign up. Now, 10 months later, I can honestly say it was one of the best decisions I've ever made. Fit Nation has become my second home. The gym has everything I need, but what truly makes it special is the people. The owners and staff are incredibly friendly and make you feel like you're part of the family. If you're looking for a gym that's clean, welcoming, and not overcrowded, where you can focus on your workouts without feeling intimidated, I can't recommend Fit Nation enough. Whether you're a beginner like I was or you've been working out for years, you'll feel right at home. Trust me--you won't regret it!
