Been away for a while and came back because this is the best club for the sober. Will is amazing, as always! He runs an incredibly upbeat, challenging and encouraging session anyone of any fitness level can get into. Come for the best workout of your life!

Have been many gyms over the years, but this place is really special. High energy classes w/ awesome instructors (esp the owner, Brian). I also love the mix of ages and abilities. Can’t wait to go back each week for a guaranteed great workout.

What a gem this place is. It builds strength from the inside out. Brian and Will are the best trainers, every class of theirs I took kicked my ass in the most amazing way. I felt stronger after every class. The way they push you to learn what your body is capable of has gifted me with so much pride and strength I didn’t realize I had. Sign up, try a class, it’ll change you in the best way. Brian is a badass and so kind, I hope this place continues to succeed cause it deserves to.

I just started Undisputed and absolutely love it! I feel like I get my butt kicked every single day. My clothes get soaked with sweat and im dripping sweat during the classes. Ive interacted with Jonathan and Drew at the Front Desk and they've been super helpful and supportive. The main coaches I've dealt with are Miles and Will, they are fantastic and give me constructive feedback on how ai can improve. Im excited to meet the rest of the team there. My peers working out are great too, its a wonderful feeling of community. Thank you all, I'm looking forward to more workouts. Shout out to Stan M., I saw him on social media and he is one of the reasons I thought to join this gym. Thank you again for creating a fun place to work out that's inviting to noobs like me.

Best, Jon

Undisputed Boxing Gym is the real deal! From the moment you walk in, you can feel the energy—it’s a place built on hard work, passion, and an unbeatable community. The coaches are top-tier, whether you’re looking to sharpen your boxing skills, build strength, or just get in the best shape of your life. The workouts are intense but fun, and the atmosphere pushes you to go beyond your limits. The new location in Redwood City is incredible—bigger space, new equipment, and the same fire that makes this gym special. If you’re looking for a gym that truly cares about its members and delivers results, this is the place. Can’t recommend it enough!

This is the first time in my life I actually look forward to working out! The workouts are always challenging and never easy; they really push you to get better with every session. The mental, in addition to the physical benefits, are incredible - I've noticed improvements in focus, resilience, and stress relief. The staff and instructors are awesome, always smiling and motivating!

I cannot say enough amazing things about Undisputed Gym and my personal trainer, Alexa Tafralis. From the moment you walk in, the vibe is welcoming and genuine. The receptionists greet you with such warmth, and all the trainers are incredibly kind and encouraging. This isn’t one of those gyms where you feel out of place—there’s no pretentiousness, no fancy clothes, and no over-the-top vibes. It’s full of real, down-to-earth people who genuinely want to see you succeed.

The gym itself is immaculate, and the environment feels so positive and inspiring. I hadn’t worked out in years and am out of shape but thanks to Alexa’s guidance, I’m improving every single day. Alexa is beyond amazing—she’s knowledgeable, supportive, and truly invested in her clients' progress. She makes me feel confident and capable, which is something I’ve never experienced before.

I’ve never loved going to a gym this much, and that says a lot! For anyone looking for a clean, welcoming, and supportive environment to improve their health, I can’t recommend Undisputed Gym and Alexa enough. This place has truly changed my perspective on working out, and I’m so grateful to be part of this community!

Glad that I found this gym! It's a hidden gem located in industrial area. But I especially love that there're plenty of parking spots in the lot! This is totally different from other boutique gyms in downtown areas.

Got a nice solid 60-min workout there, friendly coach and spacious gym for sure. Also found it nice to have the bag and bench placed together, so we don't have to move back and force to different spots during classes.

Undisputed boxing gym is clean, has great music and friendly staff. Mike has been a personal boxing trainer for my 13 yr old for almost a year now. He is patient and supportive, and my son leaves every lesson exhausted and proud of his growth. This is one of the best gyms and great for all ages. Thanks Undisputed!

Great boxing, cardio and conditioning class. Full 60 minutes with a nice mix of weight/strength mixed with HIIT work based on classic boxing moves. Clean, plenty of space, and very nice bathrooms with showers/towels.

If you’re looking to find a post-pandemic fitness routine near the heart of Redwood City, you have to visit UBG. As a new boxer, I wanted to train in a safe and friendly environment, learn basic techniques, and get my strength and conditioning up through a well balanced and intense HIIT program. I love the energy of the coaches and staff, who are always attentive and there to hype or guide. The extra equipment and training space is a huge asset as well. Give it a try.

You need to cancel your credit card to cancel this membership. I’ve tried for months to stop the charges. Awesome gym but if you move you can’t stop the charges.

Recently joined as a member after taking private boxing lessons from Victor Pasillas (Note: If you are looking for an awesome boxing coach - highly recommend Victor!). I was able to try a couple of classes and decided to join. Classes are challenging and always different - so far I've taken classes from Jenna and Bryan and both are fantastic. The women's bathroom is like a day spa. The facilities are well maintained and they offer classes from early morning to later in the day. One of the great things is they don't have any lengthy contracts - you can sign up month to month or you can also buy class/use packages - even offer a 'First Time" package that gives you two classes and a set of wrap. Great place!

The absolute BEST thing about living in the Bay Area is a place like this... Great workouts for all walks of life and for every degree of personal intensity. When I battled severe PPD after childbirth and couldn't safely take meds due to breastfeeding, this gym was my savior. If you're looking for a second home and want to feel good about your level of efforts, this is THE place for you... If you want to feel good from the inside out, take a step inside and you won't be disappointed. The staff aims to please and you will surprise yourself :)
