    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most part with a variety of equipment but weights are not well…read moreorganized and the equipment there is visibly outdated.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.

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.

    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!

It's only 30 minutes but I leave drenched in sweat, feeling accomplished, happier, and stronger every time. The coaches are great, the music is always fun, and the energy keeps you going even on the days you don't feel like showing up. ICF, my happy place! 10/10 recommend!

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 one of my preferred spots in the East Bay for the layout alone. However, the cleanliness is a major drawback. The carpets have clearly seen heavy foot traffic and are holding onto a noticeable odor--a good shampooing is overdue. More importantly, the mats are dirty; I found significant grit and grime on today before stretching(see photo). I always wipe down equipment before and after, but the level of buildup here is tough to ignore. With some better maintenance and floor care, this would easily be a 5-star gym.

The calls come daily, sometimes multiple times a day and have crossed the line into harassment. I already called weeks ago and spoke directly with Carlos to have my number removed from their marketing list, which I never signed up for in the first place. Despite that request, the daily calls continue. After another unwanted call today, I contacted City Sports and spoke to Assistant Manager Henry and made it clear that if my number is not removed immediately, I will explore legal action, including a potential class action complaint. City Sports Hesperian seriously needs to reevaluate its marketing practices. Repeated unsolicited calls after a direct request to stop are unacceptable, unprofessional, and harassing.
