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!

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.

Very nice and clean gym! They have a lot of machines you won't find at your average gym!read more

Had a decent workout here over the holidays. They have some really great equipment that is hard to…read morefind elsewhere, especially for building glutes (multiple hip thrust machines from Peach Builder, RDL machine which I've never seen anywhere else, standing hip abduction, angled squat, you name it). 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.

If you're looking for a personable and knowledgeable trainer, then Truong is your guy. I've been…read moreworking with him for the last 2 1/2 months and can say I've lost a ton of weight and body fat. But the most important part is the way he's shaped my mindset in terms of lifestyle. There's so much info out in the internet, it's impossible to filter out what is best for you. 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. In addition to his training, he's also just a cool guy to talk with in between sets. The sooner you sign up for his program, the sooner you can start working towards your ideal body!!

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 have been training with Joe for over five years, and it has truly been a game changer…read more Before working with him, I was in constant pain from my desk job and relied on weekly visits to my chiropractor. Joe taught me how to improve my posture, move correctly, and build a stronger mind-body connection. Through consistent functional Patterns training, my pain gradually eased, and my chiropractor visits decreased from weekly to just once a month. Beyond helping me become stronger and more mobile, Joe has given me the tools and knowledge to take better care of my body every day. I'm incredibly grateful for his guidance and would highly recommend him to anyone looking to improve their health, mobility, and overall quality of life.

I started going to this gym by taking personal classes with Anthony. After a year of training with…read morehim, I built my confidence (and stamina) enough to sign up for Leo's strength and conditioning course. Five years later, I married Colin--a fellow iron warehouse weightlifter. Now we have a baby, and I'm trying to find time to get back to the gym. Even though we live in Castro Valley, we try to find time to go to Iron Warehouse because it's worth it for the community. Leo does an amazing job of uplifting people that want to get into shape--and stay in shape! Truly, he creates a community in this little garage gym. It's the kind of place where people wave hello to each other as they arrive. You get out what you put in. Get ready to sweat. :)

This place is phenomenal! I'm doing personal training here with Michael Truong and this guy knows…read morewhat he's doing. I was able to have a consultation with him to discuss my current abilities/limitations and my goals, and he designed a personalized program for me to achieve success. His credentials are on full display through his extensive knowledge on proper form, mechanics, and motion of the body. He is not intimidating, but will motivate you to give 110%. Also, his payment plans are reasonable and won't burn a hole in your wallet. Michael pushes me to be the best I can be and I have no doubt that with his support I will be able to exceed my goals. I am a big fan of the open layout here. I don't feel cramped at all and feel completely comfortable/confident with the space they provide. They also have an abundance of equipment/tools for you to not only accomplish your own fitness goals, but to explore new ones as well. There are plenty of amenities and programs they offer for your to explore; however, I have yet to experience them so my review is limited in that regard. Ultimately, this is is a wonderful facility to repeatedly lift heavy things and put them back down, and I recommend you come check it out.
