Community is humble, passionate and about the right size (not too big feeling crowded or not too small). I have gradually improved in all dimensions - strength, cardio, flexibility, technique and mindset/mentality. 5 stars! Highly recommend.

I've been going to CrossFit One World for about 14 months now, and it's been a great experience. I…read morefirst joined the Boot Camp program, and coaches JP and Moe really made a difference for me. 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.

For the past year, Yo has been my fitness trainer and holistic nutritionist. She has strongly…read moreimpacted and changed my life. Before meeting Yo, I was not satisfied with my body and believed that I would not be able to ever feel confident about my physical appearance. Yo was able to help me feel confident and hopeful about results. She gave me tangible tools and knowledge that will serve me for a lifetime. I've lost about 20 pounds and gain lean muscle. I've tried many other forms of fitness and this was first time that I saw and felt, healthy, results. I'm still in the process of continuing my transformation journey. However, I feel healthy, strong, and empowered. When I took my first class at Underground Fitness II, I instantly felt welcomed. Yo greeted me enthusiastically and ever since she has been one of my greatest supporters. During this past year, I have participated in Yo's fitness classes, nutrition classes, and I have observed many amazing qualities. She plans challenging workouts that is suitable for all of her clients. She takes time to get know her clients personally in order to plan effective workouts. She is always willing to discuss my most pressing questions about fitness and nutrition. In addition, her passion for fitness and nutrition is so moving, she is able to translate this passion to her clients. I'm always eager to share what I learned to my friends, colleagues, and family members. Lastly, Yo is devoted, resourceful, and compassionate to her clients. Her work is AMAZING, and I strongly recommend her as a trainer and nutritionist. Her love, care and commitment to her clients and profession is undeniably transparent.

I was hesitant to start my own personal training based on the cost and because I felt like I didn't need it, but it's totally worth it! I feel mentally and physically stronger! I look forward to coming, but then dread it for the hour just because some are the workouts are so hard/tiring. It pays off in the end though! She's so supportive, a great listener, super energetic, and knowledgeable. I definitely recommend her

My son attends Kajukenbo on Tuesdays and Thursdays from 5:30-6:30 PM, and I've taken full advantage of the fitness classes offered during the same time. I'm incredibly grateful for the knowledge, guidance, and encouragement shared by the leaders at Dragons Den. It's been such a blessing to have an opportunity to invest in my own health and wellness while my son does the same. What makes Dragons Den so special is that it goes beyond the gym. The confidence my son has gained through the encouragement and support of this community has been amazing to witness. From the classes to the activities outside the gym, including the women's self-defense class that I've truly enjoyed, there are so many opportunities to grow, connect, and build meaningful relationships. Dragons Den is more than a martial arts gym - it's Ohana! We're so grateful to be part of a community that pours into its members both on and off the mat. If you're looking for a place where you and your family can grow stronger physically, mentally, and emotionally while being surrounded by people who genuinely care, Dragons Den MMA is the place to be!

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.

While I went to town leaving reviews for Waterworks itself, I realize the intimate culprit is City Sports. Their pool is constantly undergoing some sort of HVAC issues which leads to ongoing and almost weekly pool closures.

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.

Shoutout to this guy for pushing me beyond my limits and keeping me in check with my diet (even though I still need work). I've been training with Shah for a little over two years. I trained previously with others, but the progress I have made with 2 sessions/ week?! Remarkable. I have an injured shoulder and knee and Shah worked on mobility and strength to get it back in shape. When people think of personal training, you mostly think about strength and endurance, but with Shah you also get physical therapy components & lots of mobility / stretching (which is what we need as we get older). I appreciate him being so patient and creative when it comes to my sessions. He gives you that 1:1 attention as my body highly needs it. Having Shah as my trainer helps my body physically and mentally. It's a nice break from my work/ home life. He pushes me to be more active & somewhat disciplined outside of the gym. So thank you.

He was previously my coach at Orange Theory Fitness and I heard he started his own personal training business. Boy am I glad I reached out. Shah adopts a holistic and full-body training program that is tailored and strategic. He works within your body's abilities but challenges you in ways that are profound. I am a working mom with a busy schedule but after working with Shah i can proudly say i am the strongest and fittest i have EVER been. Thank you, Shah!
