I was a member here for almost 6+ years, and I finally decided to cancel. The biggest reason for…read morethis review is 100% due to management. Over the last 4 years, my monthly fee was going up. I probably contacted once a year to figure out what was going on, and was told "management will get back to you". They never did, up until a few weeks ago. The reason my membership went up was because back in 2018, the "Dues Lock In Fee" was never paid (they literally have my card information on file). At the time of signing up, they said my monthly fees wouldn't go up. It took you 4 years to tell me that?! To which management said "Well this is the first time I am hearing about this, and I called you right back". Yeah, no. Again I have been trying to contact management for the last four years, and not a single response. To find out, again this was due to an error at the time of signing up? In trying to resolve it, I had two options. They could throw in some personal training (which I declined, since I am being trained by their former trainer), or I could sign up for the Lifetime Membership which they would waive the annual fee. I ALREADY PAID AN ANNUAL FEE with my current plan for the year! Ultimately I said look if you can bring it down to the original price, I'll continue being a customer with yall. They couldn't, so I decided to leave. I genuinely wanted to stay, but with the way management dealt with this, no thank you. This gym is extremely dirty, and I have gone at almost all times. I know they have people who clean the gym, but it's disgusting. Bathrooms look like they are cleaned once, and 9/10 times it's always dirty when I come. I feel like the same machines are always needing to be fixed. The only good things about this gym were how polite the front desk workers were and their inbody scan! Erin is extremely friendly and so polite! I didn't work with all their trainers, but the one I did work with was amazing. It 100% sucked to see her go. The best part of the gym was the in body scan (probably the only reason I wanted to keep the membership). If you are looking for a basic cheap gym, please by all means go ahead.

I had no background in CrossFit or weightlifting and felt completely new to it all, but they explained the basics clearly, kept things motivating, and often stepped in to correct form so we built the right foundation. That gave me confidence and made the classes something I looked forward to instead of dreaded. Over time, I enjoyed Boot Camp so much that I moved into CrossFit. I'm still a beginner in CrossFit and probably will be for a while but my weight loss has accelerated since making the switch, and I've started feeling stronger, healthier, and more positive overall. So far, I've had classes with seven different coaches plus Brad, the owner, and every one of them has been dedicated, approachable, and engaged. Each coach has their own style, which makes it fun you pick up something new in every session. Brad himself is humble and very committed to building the kind of community that makes people want to keep coming back. The best part of this gym is the great community of coaches n people. It's full of people who push themselves, encourage each other, and make the hard work enjoyable. If you're looking for a place that challenges you but also supports you, CrossFit One World is it. Joining here has been one of the best decisions for my health and well-being.

I have multiple injuries and body issues that make it hard to work out. I was always injuring myself the moment I tried to do weight training on my own. With Awesta I give him feedback on when something is challenging or exacerbating an issue--I'm learning good form to avoid injuries. He is always responsive and finds modifications so I can stay engaged the entire work out. I also find it more affordable than I expected. I don't do the group classes though they look great, it's a bit too advanced for me given my limitations. Being in there a few times a week, I watch the entire staff cultivate a warm, welcoming environment where you/they say hi to everyone who walks into the space. It's also very diverse. I'm talking both staff and members, culturally, age-wise, body types, genders--no one ever makes you feel you don't belong there.

Rating: 4.5/5 - this review is based on one class…read more This gym is great for beginners and an older crowd. I didn't realize how much of a gym desert Castro Valley is until today. I'm originally from San Diego and there are plenty of gyms around my area. However, my sister did mentioned she lived in an older more suburban neighborhood. Unfortunately, I wanted more of a challenging HIIT class that you can find at Barrys or F45 (both of which are an hour away from here). With that being said, they do have TRX bands and assault bikes as well as a variety of weights. They also offer beverages between $1-$5. They were also nice to let you use the assault bikes before and after class. I was expecting more of an energetic and motivated crowd but it was more of a mellow crew of retirees and a preteen boy. It was definitely not what I expected in a bootcamp/HIIT class. Nevertheless, it was a great class albeit I felt like the only gym rat there. Earlier in the class, there was some confusion (partially because the trainer was also teaching people online) but he was able to modify some of the routine so most of us understood what to do. I never expected wanting to do more after a workout but this is a great class if you want to be challenged but not physically exhausted. I also recommend a voice amplifier and more prompts (i.e lift your arms above your head, etc) for the trainer as there was some confusion (maybe due to the music, his low tone or lack of prompts). Will visit again if I'm in the area as it's relatively close to where my family lives. Parking: Plaza Parking Recommendation: They have a first timer special - 3 classes for $50 that includes personal training but I would check online or in person to make sure that it's accurate. They also offer open gym to those with classpass!

Located in a large plaza - Parking is also very convenient and always available. (++ big win with a Starbucks right around the corner which just makes things so much easier when you're on the go!) I do understand the frustration sometimes on booking and with classes getting canceled. But as an unlimited member I do think it's still worth it - esp. now with the option to have multiple studios which makes booking ahead and finding classes a bit easier. Another main reason why this location is one of my favorites is because of BRITTANY!! Every class with her reminds me that these glutes, cheeks, and inner thighs gotta go to work! She makes a great effort to check in with everyone on how their body is feeling before starting class, fixes you (with permission ofc) to make sure you get the most out of each movement, and switches up the classes so it's not super repetitive. BRITTANY is def. one of the BEST!

Everyone there is so warm and welcoming, and there is no judgement there at all. There are so much laughter and chatter, it's always such a warm and fun atmosphere. I know it's seems almost impossible to wake up at 5am and be at the gym by 6am for exercise, but once you get into the rhythm of starting your day early and sleeping early, it does wonders for your body and energy! The pricing is also very affordable, and bootcamp membership is offered in chunks of 3-months/6-months/a year. I'm only be in California for an undetermined amount of time, and after expressing my concerns, Mitch was very understanding and accommodating, so we were able to find something for me. Time flies really fast during bootcamp, but what I really appreciate is that there's no pressure to do beyond what you're capable of, you can go at your own pace and no one will judge you. Dianne and Mitch both demonstrate each exercise so it's easy to follow along, and they keep track of how many sets of each exercise we do. One of the biggest things they emphasize is correct posture, so you don't accidentally injure yourself during exercise. I've walked out of gym feeling all my muscles aching (in a good way!!) and I definitely am feeling so much healthier and less antsy I recommended my sister to come here as well and today was her first day of PT. It's her first time going to a gym for exercise, so having a PT to personally guide her was a good choice. She said it was a little bit of a challenge but she appreciated how attentive they were to the exercises she could do and the ones she struggled with. Needless to say, this was a great choice for us!! Thank you so much!

Prior to coming here, I inconsistently would go to the gym.

If you are a beginner or getting back into your fitness, no matter where you are in your fitness journey, you should consider coming here.

The HIIT classes change daily, and the class schedule has many options to choose from, which makes it easier to find a time that fits for you.
