Reviews from you

I love this gym. The owners. coaches, members, and staff are all a very welcoming and encouraging group no matter your fitness level or background. The owners, Coach Cesar and Shirlee, care about their members, take their time to answer questions, and are interested in hearing feedback for providing the best experience and classes/ class times. They have a high standard of cleanliness and care for their facility and creatively make the most out of their open space format, which opens up to the parking lot in the back.

I've been working with stretch coach Lorrie for several months now, and I can't overstate how effective her program has been for me in terms of increasing mobility and eliminating back pain. I've been training in martial arts for over 20 years, including MMA, boxing, Kajukenbo (2nd degree black belt), and BJJ (black belt). For the past 3-4 years, I've been struggling with chronic back pain (like so many people who train BJJ). Then in March 2022, I had cervical spine surgery and needed even more help with muscle activation, pain management, and neck and back mobility. I saw Lorrie's bio while attending a boxing tryout class at Rumble City. So glad I decided to go for it.


JACKIE VASQUEZ

A friend introduced me to RCB and I have not left since my first class! From the welcoming and amazing staff who are so inviting and consistently bring such a great energy to the classes- you really feel the sense of community. Their coaches make everything really approachable and they consistently strive to make you better- the most fun I’ve had working out in a long time! :heart:


HEILA AHMADZAI

I really enjoy the classes at this gym! Unlike many other cardio boxing classes, here the coaches actually correct and focus on your technique. I never miss coach Sara's classes, they are a lot of fun, and no 2 classes are the same! Coach Cesar and Pat are incredible too! Definitely recommend this gym :+1::boxing_glove:


ARIJIT CHATTERJEE

I've been coming here for about a year now, and can't recommend this place enough! The coaches are all super welcoming, experienced, and they change up their classes so it always feels like you're doing something new. I especially like how the owners and the coaches make such an effort in getting to know their members and really help push you to meet your fitness goals. If you're on the fence about joining a new gym, they offer a free first class, so you can try it out!


TINA TRAN

Great staff, coach Cesar makes sure all members are well taken care of and getting the training they need. The equipment is great and there is multiple classes to chose from and different schedules to fit your time frame. 5 star boxing gym!


AXEL MENDEZ

I love my experience and RESULTS from Rumble City Boxing! Coach Cesar goes above and beyond to hire experienced and knowledgeable staff for his clients. They accommodate all levels of training from beginner to experienced. Their schedules are perfect to keep a consistent routine and target all the goals. Great family vibe and personalized one to one communicative staff who will always take the time to answer questions


ASHLEY AMORY

Coming here feels like i'm with family. I've never felt judged and have always loved working with all the different coached. I've seen this gym come from nothing to building the best boxing gym in San Jose period.
