    As someone who is inexperienced in strength training, Gustavo curates such a fun and fulfilling space to learn. Highly recommend!

    I'm so glad I took the leap and decided to join Moxie! I was previously a member when it was D's…read moreFitness, and after being away from the gym for quite a while, I wasn't sure what to expect. What I love most is that Moxie is a women-only gym. Even when it's busy, it never feels overcrowded or overwhelming. The gym has lots of updated machines and equipment, and it's always clean and well-maintained. The staff are incredibly friendly, welcoming, and make you feel comfortable from the moment you walk in. A special shoutout to Cassandra! She seems to know everyone by name, which really speaks to how dedicated and personable she is. She always takes the time to greet members and genuinely helps create a warm, welcoming atmosphere. Thank you, Moxie, for making it such a positive place to get a work out in. I'm so happy to be back!

    It's an ok gym, pretty clean for the most part with a variety of equipment but weights are not well…read moreorganized and the equipment there is visibly outdated. It would be great to see some newer equipment and additions like a Smith machine or hip thrust machine. My sister and I had an uncomfortable experience when we visited together. A trainer asked us to swipe in separately, assuming we were trying to share a membership. The way we were approached didn't feel very welcoming or respectful. It's also frustrating to see the owners opening a new Pilates studio while this location still needs updates. And honestly, for a women's-only gym, it's surprising there's no childcare option. I think that would make a big difference for many members. I prepaid for an annual membership and honestly unsure if I will renew when the time comes.

I…read morehave been training here almost every day, and I can say with confidence that this is more than just a gym--it is a community. The no-class-time model is incredibly efficient for a busy schedule; I never have to stress about a clock, I just show up and get to work. What makes this place truly special, however, is the warm and inclusive atmosphere: A Personal Touch: From the moment you walk in, you're greeted by name. There is a genuine culture of kindness where members cheer each other on through every round. Celebrating Milestones: One of my favorite parts is how we celebrate each other's progress. Whether it's a 100-workout milestone or a 500-workout achievement, the trainers and members make sure your hard work is recognized. Expert Coaching: The trainers are the perfect blend of professional and encouraging. They provide expert technical guidance while ensuring you feel motivated to push past your limits.

The facility is always clean, the equipment is well maintained, and there's a great variety of machines and free weights, so you never feel limited in your workouts. What really sets this gym apart is the atmosphere. The team creates an environment that's motivating, supportive, and focused on helping people reach their goals, whether you're just starting your fitness journey or you've been training for years. The trainers are knowledgeable, approachable, and always willing to offer advice or encouragement. If you're looking for a gym that combines great equipment, excellent customer service, and an energetic community, Crunch San Lorenzo is the place to be. Highly recommend to anyone looking to improve their health and fitness!

Instead of explaining the policy, he was RUDE, dismissive, and made us feel uncomfortable. When we asked about a guest pass, he bluntly said no. After we came back with a buddy pass, he laughed in our faces. We were also never informed there was a $10 option to attend, which we would have happily paid. We ultimately left and went to 24 Hour Fitness using my daughter's membership, and had the complete opposite experience--staff and instructor were welcoming and professional. Time to change gyms.

    I've been going to personal training for 9 mos. every week with Awesta and highly recommend him and…read morethe team at Body Mechanix. 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!

Reached out to a email promo by someone there never responded and later remembered again to just email the website. I was diagnosed with heart failure causing parts of my body to swell up and gave me anxiety. To be honest gym membership was the least of my worries. Being a single mom worried and scared about my diagnosis left me putting more important things above all else and i really forgot about the membership. so i'm not going to bash a business for their lack of compassion but since they were selling it online like they cared about your health and well being, at least you can do is comp me for the paid in advance over $1k for a years membership. I'm not asking for a whole year but some sentiments along the line as we can help you with a few months since you weren't physically here in the gym to work out, would have gave me a better impression about the business. they said "you only got two months left so we froze for your future use unfortunately that's all we can do." It was almost like your well it's your fault you forgot when you found out you're dying, no compassion at all. Writing this as a reminder to those who are a bit forgetful. If shot in the foot or cut off an arm remember to freeze your membership right away. Use it or Lose it type membership at this place.

It's definitely dirtier than my local City Sports in Sacramento. The worst part about this club for me is that the free weights were a complete mess. The dumb bells appear to be in random order and plates seem to be haphazardly put back as well. I got here at 5am when they open and there was an old plastic water bottle on the floor. Seems like no one is taking care of this gym. Not specific to this location, but City Sports Club needs to open earlier on the weekend. 8am is ridiculously late. Would love to see 6am or earlier Saturday and Sunday like almost every other gym does. With all of that said, this gym does have a good variety of equipment and I appreciate that City Sports has locations all over Northern California I can access.
