One Workout That Does It All - connect Iron Flow, Strength, and Cardio movements in our signature group class. We always start with a guided warmup to prepare you for the upcoming workout. We believe warmups are essential, and we design each one to prepare you for the specific movements you'll do in class.
Formed in 2019 as a community center program with a group of friends, IBX Fitness has since evolved into one of the best gyms in the East Bay Area with the goal of providing fitness that can be maintained for your whole life. Strength builds muscle, cardio keeps the heart pumping, but we wanted to find a better way to connect these two training styles that could provide the best of both worlds.
First, we'll give you a quick tour of the facility. Then, we will sit down and answer any questions you might have about who we are and how we train at IBX Fitness. Then we can determine the next best steps customized to your goals, needs, and fitness level. Either way, this is a great starting point and you will leave here with some great advice.

I’ve been an IBX member and fan for several years and give huge kudos to Ian and Bri for weathering the shut down by transitioning to online workouts and recently opening a beautiful workout studio. Their excellent trainers go above and beyond and I always feel supported, challenged, and safe. Best if all, I continue getting stronger with more endurance!

IBX does it right! The group camaraderie here is really unmatched elsewhere. When the pandemic closures started, IBX was quick to accommodate all of us by keeping classes going virtually. They also provide monthly newsletters to keep us in the loop along with surveys to keep us happy (and they actually use their feedback to continuously improve!) I am so happy I kept my membership going through all of this craziness because this is exactly the kind of small business we should all be supporting.

Very impressed with the IBX Fitness exercise format and team. I believe this program will compliment anyone at any age or athletic level. Furthermore, they are fostering a great community beyond just physical fitness. Their staff and members are an all around great group of people.
Incredible how IBX quickly transitioned their classes to online during this pandemic, and they continued to host social gatherings online as well.
Five stars on all levels without a doubt. Do yourself a favor and join IBX Fitness.

I highly recommend IBX! I joined more than a month ago and it is super easy to connect with all the members. I already feel part of this very supportive community. Further, the motivation to maintain a regular workout schedule comes easier to me.
About the workouts: The crew of energetic IBX instructors prepare workouts very carefully with different options to scale the difficulty based of individual levels! They show the movements and sweat with us during the workout. While very careful of the safety and teaching the correct movement, they also look at our form and help us correct it if needed

Love it here! Even with social distancing, IBX has accommodated all my personal workout needs. They've moved classes online to an accessible Zoom platform, and I highly recommend their online classes (and eventually their physical classes) to stay in shape during the pandemic. They've also built an amazing community and network of kind and inspiring people.

Thank you IBX for putting together a rare blend of workouts with motivational instructors and a welcoming, supportive, and fun community! I cannot recommend this place enough for anyone (of any level!) to come get a workout and have fun while doing so. I have always struggled with working out on my own, so this group keeps me accountable.
What I appreciate - Feedback is always emphasized as they're always looking for ways to improve their program. I feel like my voice is always heard and they do try to implement changes quickly, if and when, possible.
An example of their superb service is how

IBX Fitness is a great place for anyone who wants to workout in a fun and supportive community. No matter what your personal fitness goals are, they can help you achieve it. My husband and I joined IBX because we wanted to be more consistent with working out. We found ourselves really enjoying the classes but what we loved was the incredibly inclusive community that the founders, Ian Birnam, Brianna Costello, and their instructors created. We met so many inspiring but fun and down-to-earth folks through IBX while working on our strength and core.
