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!

They also have a ton of squat racks and benches available so you can probably always find equipment--we came while half the squat racks were taken because a class was in session and we (3 of us) still didn't need to wait for any equipment. My only complaint is that there is no designated room for the classes, so it can get really loud while they're teaching them because you have to work out in the same area. It would have been good to have a warning about that before.

But Truong is an expert and caters diet and exercises to what your body needs, knowing the perfect amount to push you to becoming your best self.

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.

Her deep, science-based understanding of physiology, especially when it comes to female and athletic bodies, is truly unmatched. She meets you exactly where you are, tuning in to your personal needs while offering practical, meaningful guidance that leads to real change. What sets Shanti apart is her whole-body, natural approach. She's not someone who pushes a Western medicine fix for everything--she's incredibly attuned to the body's natural rhythms and honors the simplicity and wisdom of how we're built. She challenges me in the best ways, always pushing me toward actual growth while being emotionally supportive and truly caring along the way. And honestly--her approach works. I've been dealing with insulin resistance and hormonal shifts, and in just two months I've experienced a major, positive transformation in how I feel and how my body functions. I first worked with Shanti before my wedding and reached my goals, and came back to her when I decided to come off birth control. The results have been even more powerful the second time around. If you're ready to take real action and make sustainable, lifelong changes for your health, I can't recommend Shanti enough. She's the real deal
