I’ve only been coming here a few weeks but really enjoying it so far. I switched from using a personal trainer at a gym and really appreciate that this is a balance between still being coached and having guidance, while also being more independent and forcing me to learn / pay more attention to what I’m doing. The community also seems great- have met a lot of people who’ve been coming here for a long time and seem to love it.


Worked out here for five months while staying in sf! A great place to get your workouts done, with super nice coaches and an welcoming community :) they do daily classes and a offer daily program you can do on your own as well.


Great crossfit gym.Fun and social workouts with good variation in exercises.Equipment is in great condition and the location is great.


Best coaches, best programming - there is no better gym in SF to get in shape and build a community.


Great coaches, great facilities, and great community atmosphere. Flagship has been my go-to gym for the last 3 years, and would not go anywhere else in SF. Coaches do a fantastic job of working towards different skill levels or personal goals even within the same class. Management is also extremely professional and member-oriented.


I moved to SF recently and tried a free Flagship class and was immediately hooked! Honestly, Flagship has been one of my favorite parts of being here and is JUST what I wanted and needed. SO many gyms/classes don't push me in the way I hope, but Flagship is the perfect challenge with support from knowledgeable, helpful and kind coaches. It's quickly become my favorite part of the day and I feel so lucky I stumbled across this awesome place.


Spent a month training with Flagship and had an absolutely great experience. I came from a more traditional weight lifting background and found the change to classes with a group to be really fun and challenging in unique ways. The coaches and members were kind and friendly. Was able to do classes but also sprinkle in more traditional weight lifting through open gym times. Hope to join again when I come back to SF.


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.


nice place. Nice coach. Huge place for u to CrossFit if you are staying nearby Castro. Must visit!!!!

I can't recommend Flagship highly enough! It's hard to find a gym with both challenging workouts and a kind, friendly, supportive community - Flagship Upper Market has both. As someone new to the city, joining was one of the best things I've done - I've met a great community of friends through this gym. The coaches are super supportive and knowledgable, and make a point of introducing themselves to anyone new, getting to know you, and personalizing your workout so that you can get the most out of it. The workouts are challenging but always have options for modifying for skill level or injury and there's never any stigma for doing the workout that works for you - you see everyone from the brand new beginner to the strongest person in the gym at some point making modifications. It's such a supportive and fun environment, and I have already gotten so much stronger!
