Flagship doesn't just provide an incredible space to work out, it also offers a welcoming, open hearted, and supportive community. I adore the coaches and the members, and as the days are heating up, the outdoor gym is a huge bonus. I have had the pleasure of attending Coach Nicole's class most consistently, and can't recommend it enough. She has gently but firmly pushed me in ways I didn't know were possible and creates an environment that is equal parts safe, challenging, and fun. I always leave with a smile on my face and a new level of confidence. Don't miss her class!! read more

At $329 every 4 weeks with limited open gym hours, you still closed one of your key locations today for Open Gym clients without any notice. Open Gym clients here are treated like second-class citizens even though we pay the same price. read more

Amazing community and 5 start programming and coaching. The equipment is amazing and really makes me feel confident when working out.

I love this gym. I joined at the end of June and it has been a warm and welcoming community from the jump. I haven't joined a gym since pre-pandemic when my gym closed. I was so sad to lose my community and other gyms haven't had the same feel until I found Flagship. Instructors have been great and have helped me fix my form from years without CrossFit and I'm starting to feel back in the swing of things again. Members have also been great to interact with and supportive of one another. I love the overall experience including their programming with plenty of opportunities for strength and/or cardio. So glad I found this place :) read more

There is a reason why Flagship Castro has a perfect review. This place is beyond awesome. The trainers make you feel like you're having a one on one session yet you are in a group which is separately exhilarating because it encourages you to push on. It's a very hands-on approach. It's also a great location to shopping ... eating - basically getting all your errands done before or after. Best of all you feel amazing afterwards only craving for more. read more

Visiting from LA for the weekend so I scheduled a drop in for Sunday at 10am. Upon entering, I was quickly greeted by Jayson, who was super sweet and welcoming. In fact, everyone was! I've been to several gyms that are pretty cliquey and feel disconnected, but that wasn't my experience here. Others were asking about my weekend plans, offering to partner up, etc. If I lived in SF, I'd feel totally comfortable making this my box. Will def be back on my next visit. Til then, can't wait to get back to LA and show off these pumped shoulders! read more

Facility? Immaculate. Coaches? Average. Been deciding between a few gyms in the neighborhood and decided to use my free workout class. Showed up early because I expected a quick run down/facility tour before class started (I mean that's why they ask you to show up early right?) Nope. Went in and didn't get greeted by any coaches - but no worries because I walked around and started introducing myself to see who the coach was. Found the coach, introduced myself and then asked for a quick run down of the facility - he didn't want to give me a tour. Just told me to wait. I then ask him where do I even put down my belongings - he points me to the back wall. You see why a quick run down of the facility is necessary? Eventually got paired with another new student. The new student was very new to these type of workout classes. He asked me a lot of what the workouts were and how the class was structured. Luckily for me I've taken a lot of these type of workouts classes so I explained everything to him AMRAP, every 3 minute on the mark, etc. It was obvious the coaches' effort and attention was focused on the students he already knew. Which seemed odd because most coaches put a big focus on new students to gauge their form, experience, etc. for safety. This was not the case at this gym given the cost for this gym. It's not only the facility that's important but also the coaches. read more

This is where I picked up CrossFit during the pandemic. I am hooked! I love this location as they have outdoor available. All their coaches are very professional and know what they are doing. Their equipments are all very new. I feel really safe working out there especially during this special time. Everyone gets their own work station during each class and have to wear masks at all times. You also have a full big tub of disinfectant wipes next to each work out station to wipe down everything before/ after each work out. Also, for some reason their outdoor space is ALWAYS very cool even on a super hot and sunny day. They have both open gym and classes available. Their admin, Will is also very responsive on any technical/ servicing issues via email as well. Love this gym!! read more

I decided to finally take the plunge and join Flagship about 4 weeks ago and....my god, I cannot express enough what a fantastic place this is. The trainers are all super knowledgeable and incredibly supportive -- whatever your fitness or strength goals are. The group classes are challenging without being intimidating, the equipment is well taken care of (by trainers and members alike), and there's a deep level of respect for everyone's comfort level or skillset, so you never feel too far behind. Classes are frequent and always on time, which is great for those who work from home and may only be able to take just an hour out of their day to maximize their workouts - but there are also plenty of sessions early morning/after work so you don't have an excuse to skip. ;) Lastly, it's also just a fantastic community and great place to meet people/make friends. Highly recommend! read more

I just joined a few weeks ago and am loving it so much already. I had put off joining because it's more expensive than my old budget gym, but the results are worlds different. Also love the real community at Flagship--I've already made a bunch of friends. Couldn't recommend more highly! read more

After a year of going back and forth between trying to work out at home and being a couch potato, I decided to try out a few classes at Flagship and got hooked. CrossFit can be intimidating but the instructors are really welcoming and patient, and take the time to show you how to perfect your form. Most classes are a good mix of lifting and cardio (rowing, assault bikes, ski ergs). The Upper Market location also makes parking really convenient and they've done a great job to adapting to COVID. Bonus perk: I came for the workout, but stayed for the dogs! read more

The Flagship - Upper Market training facility with indoor and outdoor set up is professional and safe. Their team of coaches push you to get stronger and perfect your technique. They provide a warm atmosphere for new members (I asked a lot of questions) and I've noticed close relationships with the known members. I would highly recommend Flagship- Upper Market for anyone looking to add to their workout routine and move their body differently. Since opening under CA order with COVID restrictions they have followed all safety protocols. read more

I've been a flagship member for 2 years now and have come back almost every day for a 6 am workout for good reason (other than coach Zach's lovable dogs). The programming is designed to provide a functional routine that balances strength, technical, and cardio movements to provide you with workouts that will not only make you sweat but improve your athletic abilities. Additionally the coaches are wonderful and attentive providing you with timely feedback on form correction and ways to improve as well as being very knowledgeable on any questions you may have. As well as being able to provide modifications to workouts for those who have certain needs My time at flagship has not only helped me in achieving my physique and weightlifting goals, but also improved more overall form and technical abilities. Whether your a beginner or expert, the classes are engaging, the coaches are wonderful, and the people who attend the classes are wonderful too. read more

The friendliest, most supportive coaches. They give you instructions on how to do each movement at the beginning of class, and walk around throughout the class to check in and help people perfect their form. They encourage you to move at a pace you're comfortable with to reduce injury. So far I've worked with Marc, Goo, Brit, James, and they're all super smart, encouraging, and kind. Every day has a different workout, and their online system is a highly efficient and specific way to track your progress. There's always a ton of space and equipment. Bathrooms are very clean and well equipped; ladies' room has stuff like dry shampoo, pins, and period products! There's never a line at the shower. Lots of shelf space for clothes. Great central location and proximity to MUNI and bus. Regardless of what level you're at, I can't recommend Flagship enough. Even just to drop in and try it out. I'm here as a beginner and feel great knowing everything in here, from facility to scheduling system, is designed to help you succeed and stay consistent towards your goal. read more

Flagship is the best fitness facility I've tried in SF (and I've been to a *lot* of places, ranging from yoga/pilates/dance to other gyms to bootcamp-style classes). It's the first place where I really felt at home. I've always done intense sports but hadn't really lifted before, so I was intimidated--but all of the coaches are so kind and helpful, and will actually correct form and give everyone personalized feedback (so rare). They have tons of classes every day so it's really easy to get a routine going, and I get a way better workout in less time than when I go to the gym and do whatever on my own. read more

I joined Flagship about 4 weeks ago and I've had a great experience so far. I was nervous to join because I'm new to this style of working out but the coaches are amazing. They're patient and knowledgeable - they taught me how to do the different exercises I was unfamiliar with. The coaches also walk around during classes and make sure everyone is using proper technique/form. The group classes are motivating and there's plenty of space for everyone (even an outside area if you like to workout outside). read more

Back again at Flagship Uppermarket. My best season ever. I managed with coaches' help to gain back strength, power, and get in shape. Extremely happy that Flagship community stays strong and has same amazing vibe as years and years before. Thanks a lot for being here for us! read more

Joined last month but wish I had joined years ago! If you're looking for some coaching and some camaraderie to improve your weightlifting, this is your place. The classes are strenuous and dense with exercises, but that's exactly what I wanted. You get an action-packed workout for 60 minutes and then you're done. It's much more efficient than going to the gym and spending lots of time resting between sets. Plus you can get help from friendly people who know what they're doing. Try it... you'll like it. read more

I started at flagship a few weeks ago and I'm really liking it. I've never really worked out like this so many of the movements are unfamiliar to me and it was quite nerve wracking starting. I really appreciate how helpful all the trainers have been. They've been very patient, friendly, and great at waking through the proper form or recommending alternatives when needed. Everyone else I've met at the gym has also been super friendly so I've felt very welcome. Would definitely recommend. read more

Great place to train. Coaches are fantastic. They give you time to adjust to the classes and movements and give the right amount of advice and encouragement to help you push yourself harder. Although I usually use one of the locations, the option to train at the other two locations is very handy. The space and equipment is all great too. Would recommend! read more

Great coaches, facilities, and equipment. I dig the wide variety of classes - standard Crossfit, conditioning, strength, oly, and even yoga - and have 3 different class times on Sunday's which is hard to come by at most CrossFit gyms. I'm just getting back into CrossFit after a long hiatus and it's nice to have so many options to ease back in and have some variety in my workout regimen. There are two floors. Ground level they can host 2 classes at the same time and upstairs are the changing rooms and an additional space for conditioning or yoga classes. Bright space with lots of windows and super convenient from FiDI for work because you can take any muni line to get their. If you register for a class and no show, I believe you get charged a fee, which for me is great to instill better discipline and avoid changing reprioritizing other things over my health and well-being. Coaches know what they're doing, are friendly, and have helpful cues for technique, and I really like the programming. My only criticism is the class sizes can be a bit too big which impacts the coach's capacity to correct your form if you're off - so if you're a newbie I suggest going to less populated class times to get needed attention. read more

When I was looking for a new Crossfit gym to join, I dropped into a few in San Francisco they were most convenient. I'm so glad I joined Flagship. Their coaches are awesome, they have so many different types of classes to chose from, they have so many different times to chose from, and three locations. Now, I really have no excuse not to show up. Anyway, aside from all of the above. The coaching is great and I'm excited to continue my Crossfit journey here. read more

I've been going to Flagship since they opened, and they are without a doubt the best gym in the city. Their coaching staff continues to improve and maintain a high standard for themselves and their athletes. Additionally, the facilities and equipment are topnotch, well maintained, clean, and since all memberships include access to both locations (the 250 Montgomery St location was open first), they're extremely convenient. Plus, they offer over 150 classes each week, including classes on Saturday and Sunday. They also offer a variety of class types, so you are able to choose your class based on your needs for that day. read more

Flagship has quickly become my second home and my safe space. The people are awesome, the instructors down to earth yet super skilled, the facilities are amazing. The environment is inclusive, high-fivevy, cheering and authentic. Small note; There is even fresh flowers in the women's changing room every day! Thanks for existing! read more

Man I love this place. The gym I was going to closed during the pandemic and it was a real struggle to work out at home, especially after working at home all day. I found out Flagship was open and signed up for their Open Gym and their outdoor set up is legit. You get your own space, your own equipment, wipes, and the coaches are there to help out and provide advice if needed. Plus, the outdoor area is gated and not spilling into the street like other gyms I checked out. I've been going here for about a month and my energy and mental health have improved. Looking forward to trying the classes soon! read more

Fantastic gym, programming, and instructors for those that enjoy the CrossFit olympic weightlifting/ metcon style workouts. Group class setting with plenty of space and equipment both indoor/ outdoor so never feel like you're on top of one another. Instructors are knowledgable and take time to explain and demo the movements, and correct form to avoid injury and improve strength. Great community as well! Would highly recommend (and already have to friends)! read more

Highly recommend! Great facility with fun, supportive people. Workouts leave you feeling destroyed, in a good way. Coaches are all very well trained and work with athletes of all training levels. read more

Best gym in the city. Incredible coaches that are very knowledgeable and helped improve my weightlifting technique. Loved the abundance of classes at all three locations, and especially loved the Olympic Weightlifting 'open gym' class at Upper Market with Zack. I got stronger and smarter about lifting and was finally able to snatch! read more

I've worked out at many CrossFit gyms all over the US, as a drop-in and a member, and this is definitely one of the best. I worked out here consistently for about six months when I first moved to SF. They have several top-notch coaches, who know when to push you vs. when to pull back and let you do your thing. More importantly, they follow a very consistent class structure, always starting with a warmup relevant to the workout they're doing, and leaving time for a cool down and mobilization at the end. The workouts are intelligently chosen as well, and the coaches will advise you on how to tackle them based on how you're feeling, which is very healthy. read more

I can't think of a single negative thing about Flagship - I love it so much! I initially began Crossfit at NC Fit (Bay Club). They had old equipment, didn't love the culture there, and the location just didn't work for me. I've been attending classes at Flagship for about 3.5 months now and am totally hooked! It has everything that Bay Club was lacking for me. The coaches are EXCELLENT at correcting form, answering questions, and 1:1 attention. They always stress lighter weights to nail down form before you start lifting heavier. And they're just genuinely cool people that I'd want to be friends with. I also loooove the people who attend the classes at Flagship Church St. Everyone is super sweet, welcoming, willing to help out. They did a great job of building a non-competitive, fun & inclusive environment. They also have an awesome selection of classes to choose from for every level, Try out a trial and see for yourself! I'd recommend Flagship to anyone who's looking for a tough workout that makes you feel like a beast or if you're looking to see results quickly! read more

There's really nothing bad I can say about this place. The instructors are extremely helpful and take their time teaching techniques to beginners/advance users alike. This gym really amazed me because of the effort each instructor took to developing a connection with individual members ( They knew my name by the end of the first week ). The gym also tries to a foster a sense of community and present opportunities to both work and talk to other members Easily 5/5 stars read more

Best box I have been to. The space is well structured with plenty of equipment for each class. The coaches really care about peoples progress and provide variations and technique cues which help people avoid the typical Crossfit car crash injuries. All programming is also put up on wodify for the week ahead, nice little touch. read more

Joining Flagship is one of the best decisions I've ever made for myself. The programming is thoughtfully-crafted and provides variety every week. The coaches are excellent - attentive, helpful with questions about form and mobility, and manage the classes well. They're very focused on ensuring you're doing each exercise properly so that you get the most benefit out of the class and don't injure yourself. It's easy to ask questions and get 1on1 instruction, even in the larger classes. I hadn't had any prior crossfit experience before joining but felt immediately welcomed and encouraged. The gender split in most performance classes is 80/20 M/F and most people are relatively fit, but it's very much a gym for every body. Highly recommend trying a free conditioning class and then the reduced-price first month to see what you think. I became addicted quickly. read more

Flagship is great and they've adapted well to the current situation around COVID. The outdoor set up at the lot is great (barbells, plates, racks, rowers) and the programming has been fun and incorporating almost all of the movements you'd normally do indoors. read more

Flagship is a great gym with top-notch coaches. I joined about two years ago with the goal of finding a new gym after moving across the country and getting over a bad leg injury. I have made incredible progress in my strength and mobility. I can't wait to see where I am a year from now. CrossFit gets a bad rap for injury/intensity but the coaches are well versed in scaling the workouts for everyone's abilities. Because of their training I was able to bounce back stronger than ever. Outdoor classes have been incredibly safe with proper distancing and sanitization measures. During the past year we never had issues with covid transmission at this gym. I'm so grateful for the coaches here (especially Nathan, Forrest, and Marc!) for supervising my growth and pushing me in ways I didn't know were possible. Coaches place a heavy focus on proper form and technique first and foremost. I love this gym, and I think you will too (especially if you like dogs!) read more

I joined Flagship after having a less than stellar experience at another crossfit gym. Things I immediately noticed about Flagship: - Clean, bright, and spacious facility - Dependable and friendly staff - And most importantly - the focus on form, training, and safety During the Foundations Course, I basically realized that I had been practicing poor form from the previous crossfit gym. The awesome Flagship team helped me with immediate course correction. I was able to quickly learn the basics and start training properly. Thanks Flagship! read more

Started coming to Flagship- Upper Market after FiDi closed due to covid-19. They offer outdoor crossfit workouts and open gym, which is absolutely amazing during this pandemic. Not to mention, great coaches and management also help make this an awesome workout environment! read more

It's been a great experience so far. The coaches are very nice and have been quite helpful in correcting my movements and improving my technique. read more

I've been doing Crossfit for about 7 months now and about a month ago I decided to try to do some drop-ins while traveling now that I feel pretty comfortable with all the regular movements. I was recommended this box by multiple trainers at my box, Crossfit NYC. There's a few basic things I look for at any box I'm attending. First one being layout and how much space there is. This place is nice and open. There's tons of natural lighting from the large windows plus an outside alley area for running/other activities I'm assuming. Second is equipment quality. They have very new looking Rouge plates and barbells with the clasps that look like gears. (those are much easier to use) The kettlebells also look new and perfectly organized into a beautiful rainbow. There's a mobility cart full of tools for pre and post workout stretching. They really thought of everything here. The attention to detail is pretty outstanding. Lastly, trainers and how much attention they give during class. My trainer today was excellent. He went over feet position when doing a squat and how that can affect your arches over time. Definitely something I have not thought of nor has it came up in any of the other CF classes I've been to so far. He also was very vigilant during the workout and helped everyone out with their form as we went along. He gave great recommendations on weight to use for the wod too based on the order of the activities. Another nice feature of this gym is that they host two different types of wods everyday, a standard wod with strength/conditioning and an endurance style wod that won't have any barbells. Also, there's several nice box dogs! :3 Overall, this is a fantastic CF Box. I felt right at home within one visit. If I lived in SF, this would be my box, hands down. read more

I have been going here for workouts for a couple weeks and so far I really like it. It is fun and motivating and the coaching is top notch. From a distance, it looks hectic and confusing but once you get into it, the exercises are intuitive. You can customize exercises according to your ability. For example, I started using dumbbells instead of barbells. And I use rings (like TRX) instead of pull-ups. There's no judgement, none that I've felt anyway. There's a warmup session to start and while wind downs aren't part of the program, they encourage you to stretch afterward. There are plenty of rollers for members to use. It's also ok to come and just do your own program on the side. (They have a strength and aesthetic program you can follow and the coach will give guidance.) It can get pretty full, so the coaches will typically gear their instruction to beginners unless help is requested or they notice you doing something incorrectly. I like the community aspect of working out together, it's more motivating than doing a slow workout on your own at a traditional gym. They allow you to freeze your membership for vacation or sickness or injury. They also give discounts for paying up front or signing a contract. As a bonus, you can bring your dog inside! I plan on signing up as I feel like this is something I can stick with. read more
