Crossfit One World & Self Defense

Highly recommend this place if you want to get back into the active lifestyle, looking to do crossfit, or want to try something new! The coaches are helpful and people are pretty welcoming. I've been doing the Bootcamp program for a few months now and it's been a super fun! Coach JP leads the program and he's friendly and amazing at what he does. His wife, Coach Mo, is equally amazing as well as all the other coaches I've met so far. I've definitely noticed a change in my strength, physique, and overall approach to fitness. The classes are challenging but there's good music and JP's dad jokes so you're going to crack in a laugh here and there while covered in sweat. Overall, the program is pretty lively and makes you want to come back for more.

It can be intimidating at first but with consistency and asking for help on techniques and lifts, it'll get better with time. Everyone has to start somewhere! The guy at the front desk (Nam) is also good at getting new members acclimated to the gym and makes you feel comfortable so don't be afraid to speak up or ask questions!

Being relatively new to the East Bay, I wanted to find a gym and community nearby. I’ve always been intimated by CrossFit and so I was glad to stumble on a bootcamp classes option on Classpass. Coach JP and Mo were so friendly and welcoming and after the first class, I was craving to come back again and again.

I then signed up for a Saturday bootcamp but the ClassPass app was having a glitch and messed up the schedule. They introduced me to the CrossFit and the rest is history. I’ve been coming to OW for a little over a year. Everyone from the coaches, to the staff, to the members have been nothing but welcoming. If you’re ever keen to joining a community, look no further.

Thank you One World!

Absolutely outstanding experience. I started here over 10 years ago then moved out of state for a while. Came back late 2023 and the atmosphere was exactly what I remembered and why I came back. Extremely challenging program, the trainers clearly put in a lot of work and thought into the workouts and again, there's just something about that box. Feels like family. Everyone helps everyone, there's no ego, no negative vibes. I've seen the transformation in some of the newbies and its just insane, including myself. If you're looking to get in shape, and you're looking for a home away from home, you will not be disappointed!

I joined One World in August 2021. I started attending the evening bootcamp classes. On my first day, coaches Jp and Mo introduced me to the class. Everyone in the class was very welcoming, and the coaches observed me to ensure I was doing the movements safely. I felt very comfortable on my first day. During my time in bootcamp, I learned new skills and developed the confidence to do movements I found intimidating before such as box jumps (shout out to Coach Lalyk for helping me build that confidence).

Eventually after a few months of bootcamp, I wanted to do more barbell movements and tried CrossFit. The CrossFit WODs are thoughtfully programmed. For example, Coach Ron programmed a multiple week cycle intended for upper body strength development. I didn't finish the cycle due to reasons unrelated to CrossFit (mostly because I was focusing on another sport I'm participating in), but I understood and appreciated his method. The coaches are experienced in the CrossFit movements, and I've observed they are supportive of the members' goals and journeys.

At this moment, I switched to Olympic weightlifting due to a change in my goals. The weightlifting program has excellent coaching--Coach Yatsek encourages team spirit and to have fun lifting. The atmosphere is supportive, and I enjoy going to every training session.

Almost two years later after stepping into OW, I feel physically great and have made some awesome friends. If you are looking for a place to feel welcomed as you pursue your wellbeing goals, come check out One World.

Amazing space for a Crossfit gym in the bay area, definitely the biggest in the tri-city! If you are looking to do olympic weightlifting, crossfit, self defense, etc. this is the place to be!

😃 I definitely get stronger and every one is so friendly

CrossFit One World & Self Defense is an impressive gym. It provides a positive environment where everyone feels welcome, and no one is made to feel intimidated. I have been to gyms with very toxic environments. This gym is the antithesis of that. There is a feeling of community, and everyone is here to do something positive for themselves, not to sit around judging others. I love the "Check Your Ego at the Door" sign at the front door. This gym offers a wide selection of programs. One would certainly find a program that is a good match for them. All of the personnel are friendly and helpful. I highly recommend CrossFit "One World & Self Defense!!!

Look no further if you are looking for a "community" of great coaches and people to achieve your fitness goals. When most of us call "One World" our second family, we mean it.

I love the flexibility of going to classes at different times, depending on my schedule. One World offers a variety of classes to pick from - Bootcamp, CrossFit, Karv, HIIT, Master's class ( for seniors), and yoga.

Each coach is unique, and they program workouts that will challenge and push you to become a better athlete. Coaches are warm, welcoming, and knowledgeable; they understand your weaknesses and limitations and help you get better accordingly. That added personal touch is what I like the most about One World. They genuinely care—the best CrossFit place in the tri-city area. I highly recommend One World to anyone, no matter where one is on their fitness journey.

Don’t hesitate to spend your hard earned $$$ here. This place is awesome!!! Coaches are very supportive. I’ve lost 20 pounds on my first 6 weeks on bootcamp, and I feel 20 years younger😉. I’m on my first week in Crossfit, and I am so excited every time I go to class. Their techniques in every exercise are unique that I guess will give you the best results.

If you're looking for a CrossFit gym, look no further because CrossFit OneWorld is the one. If you're new to fitness like I was don't worry because all the coaches are very supportive. They will always demonstrate a modified or different version of a movement. The members of CrossFit OneWorld are all different ages, size, weight, etc and come from all walks of life. This gym is phenomenal and has an even better community. If I could give more than 5 stars I would.

I've been a member for 5 years and I can call this box my 2nd home. I train here 6 days a week. My kids train here. They have a kids program. I love the community. They support and encourage you. The positive environment makes a huge difference. You don't feel intimidated. The coaches are great and knowledgeable. I would definitely recommend this place to my friends and family.

I had the best time at CrossFit One World. I was genuinely surprised by everything they have to offer from CrossFit, Yoga, Krav Maga classes to professional and personable coaches. I truly felt like I belonged to a community here and I could easily have a conversation with anyone in the gym! I have been to many CrossFit gyms across the country. No other CrossFit gym offers the an experience comparable to this one!

JP aka Joseph Philip is Dope :) He make sures you are doing exercise the right way and also make sures you are WET with sweat by the time you leave Boot Camp.

Keep up the good work JP 🤝👏

Guys let me tell you fitness is like growing a small plant. you have to take care of the plant water it daily and put some fertilizer if need and slowly grow.

This is the most friendly gym I ever attended. Do not give up hope and keep trying. 80% of it is your diet, reduce carbs and increase protein AND most importantly do only what your body can support SAFELY. for me SAFETY is more important any thing out there.

Important Tip : Please measure your success by doing body composition test, biweekly or once a month. I use Inbody scan. Its available in Max Muscle Nutrition shop. I worked hard in crossfit but did not maintain nutrition I DO NOT want others to make the same mistake.

I Hope crossfit Union city also purchases one In body scan to help customers to see their progress.

I started doing jiu jitsu with the One World crew and Mike Prudencio back in 2008 and I eventually earned my blue belt while training there. Prior to training at One World Jiu Jitsu I had been the judo team captain at San Jose State University and had trained and traveled all over the world for various judo tournaments. What kept me coming back to One World was not only the family atmosphere, it was Mike Prudencio's passion for his craft and his world class coaching ability that hooked me.

In 2011, my brother and I moved to Portland, OR. to open a judo dojo. When it came down to planning the feel and attitude of the dojo, we noticed that we kept referring back to "the way One World did things". The camaraderie that is present at One World is like none other that I have been a part of. If you're looking for high quality jiu jitsu with a great atmosphere, no ego, technical practices, and friendly people, look no further than One World Jiu Jitsu.

If you're looking to a gym to work out with fun, this is the right place for you!
They offer Crossfit, Bootcamp, Krav Maga, Jiu-Jitsu, Yoga, Powerlifting, Olympic Weightlifting, Boxing, and much more... The place is spacious and the coaches are knowledgeable and friendly!

Dropped in while on a business trip and was made to feel very welcome by Bradley. Well equipped, nice space and easy parking. Friendly members too. Highly recommend!

One World has completely changed how I view myself. I now know that every day I’m one step closer to being stronger than I was the day before. even when I have a bad lifting day I know I can always come back the next day and start all over.

Instructors really work with you to improve your technique and harness your potential. They really know their stuff. Great place to learn and train.

Thank you. For the warm welcome. The working out and the coaches.You guys were truly magical

Brad is just great! This is a place where you'll feel like you're amongst friends.
