Bailey is both professional and genuinely fun, creating a motivating and welcoming atmosphere. The people in the class are just as great--friendly, supportive, and a joy to work out with. Every session brings something new, with workouts that target different parts of the body, so it never feels repetitive. I truly can't recommend this bootcamp enough.

Training with Bailey has been fantastic -- he calibrates each session to push me one step further each time and knows how to make a session productive even when I'm injured or not at 100%. Bailey also will combine conditioning with hitting pads, helping to build those muscle areas that matter for the actual fight. It's incredibly exciting to see myself improve month to month both in terms of technique, new combinations, and greater strength, conditioning, and flexibility. He also makes sessions so much fun! Highly recommend!

I took a little break from my home gym to come here for my first class. I've know about Barry's for…read moreyears but always chickened out coming because I'm averse to treadmills. I used to run competitively outdoors, so running inside on a treadmill doesn't hit the same. Still I gave it a chance and am quite glad I did. I joined for a 9:30 AM Saturday full body upper body focus class, and it was super energizing. With rapid spring and strength sets synced to a pulsing, high-octane playlist, the workout started my weekend on a high note. Aside from the workout, what facilities I saw and used were clean and odor-free. Staff were polite but a bit rushed. The layout of the room the class I took was held in was a bit confusing to navigate in the dim lighting. They do have a reference map at the check-in desk, so it's definitely a good idea to arrive early and review it first if it's your first time here.

She's a real cheerleader for all students! Class was tough but rewarding. I love the full-body HIIT workout involving both lifting and running. The music was flowing and the class was united. I swear Barry's is harder in SF than on the peninsula or in other cities! My body is sore for longer. Great location accessible via public transit and bikes (though I walked--not from my office, but it is very accessible from people's offices!) Nice locker rooms but small. I like the soap they offer! Lockers are easy to use.

The workouts here are…read moreconsistently challenging, well-programmed, and effective--you leave feeling worked, accomplished, and stronger every single time. One of my favorite things is how each coach brings their own personal twist to the workouts. You get variety without chaos: different coaching styles, creative programming, and fresh energy, while still keeping things structured and intentional. It never feels repetitive, and the coaches genuinely care about proper form, motivation, and helping you push past your limits safely. On top of that, the community is incredibly welcoming. Whether you're brand new or a regular, everyone is supportive, encouraging, and easy to connect with. It's the kind of place where people cheer each other on and celebrate progress, big or small. If you want great workouts, passionate coaches, and a positive, motivating environment, O2 Body Fit is absolutely worth it. Highly recommend.

Every time I've been, there's something new I'm learning or a new form I'm getting down. If you're bored of going to the gym, I recommend this bootcamp to add into your fitness rotation. All the instructors are very supportive, and really does try to help you and push you to do your best. Also, the music is great and love the water machine.

Many boxing classes often focus on cardio boxing or kickboxing with minimal focus on actual boxing…read moretechniques. What I like about this gym is that the instructors all have boxing experience (not just fitness or cardio kickboxing) and provide instructions on boxing techniques. The gym is fairly large with an ample amount of heavy bags. There is a section for weight lifting though I hardly use that. Finally there is an open area for sparring for those interested. To start, you have to take a few introductory boxing classes where you learn the basics of their boxing techniques (e.g 1 is jab, 2 is cross, 3 is front hook punch, etc.). After that you can take the other more advanced classes. I typically take the Old School Boxing Class. The Old School Boxing Class consists of a 5-10 min warmup, some basic boxing warmup like shadow boxing, some partner drills, and finally some punching on heaving bags. Good workout for an hour.
