Fantastic experience: Golden State Crossfit has great, friendly coaches. This place has a positive workout environment, everyone is super nice and very supportive. The coaches provide great techniques and adjustments for your skill level, which are so helpful to make you feel comfortable during the workouts. I really enjoy being part of this gym, they encouraged me to do well in my fitness progress. Highly recommend Golden State Crossfit.

Fantastic experience: Amazing team of trainers and fellow CrossFit athletes! Makes working out to reach my goals more fun and more rewarding! Update: it’s been 9 months and I have seen such a huge change in my cardiovascular and physical health. All the coaches and my fellow athletes are amazing, supportive, knowledgeable, and keeps me motivated. I can’t express how grateful I am to have found a great CrossFit family in GSCF!

Golden State CrossFit

Hey Cindy! This is what we love to hear. We are so looking forward to seeing you crush those goals!

Fantastic experience: For a while I was contemplating about getting back to physical fitness, I tried going to my local gym but the motivation just wasn't there. I stumbled upon Golden State Crossfit, on the internet and decided to give it a shot. I've had stories about crossfit, so I was a little skeptical. It's been 3 months in, and honestly the best decision I ever made. From day 1 everyone makes you feel like you belong, and they push you to be the best version of yourself. It has that team spirit that I was looking for, and glad I found it. From the coaches, who are highly knowledgeable, to the gym members who push you everytime. It's truly a community of awesome human beings with a shared goal of being fit. Will be back after 6 months to share my progress. Love it here.❤️

Golden State CrossFit

Arnold! We are so excited to see what the future has in store for you. It’s been an absolute pleasure coaching you and I know the journey has just begun. Let’s go!

Fantastic experience: Just started here a few weeks ago and it is the most structured and welcoming Crossfit/ group fitness facility in the bay area. A wonderful community has been created here. Drop in and check it out! You won't regret it

Fantastic experience: As a busy professional, I can say if you want to put yourself first.. try coming here. Everyone is supportive and helpful. It’s a different workout every single time … so basically just show up! Thank you to the team

Ashley hellcat 1 year ago

Negative experience: Didn't do what I hired them to show me how to do. I wanted to learn how to lift not do squats. Wasted money for nothing. The first time they never even got back to me and I had to chase them down for training. I wouldn't recommend. On a positive note everyone there is nice And very friendly.

Golden State CrossFit

Hey Ashley, jamesia here! I’m so sorry you felt this was your experience. I do have to chime in respectfully since I was the one who put you through the first session. We focused on squats quite a bit due to dialing you in on technique. I wouldn’t say it was wasted since that is such a fundamental movement in our training. Unfortunately we didn’t get to lifting or barbell movements because you didn’t come back for the next 3 sessions, even after checking in and trying to schedule on your own timeline without pressure. I told you from the get go, I needed you to show up in order for us to help you. Hope it’s not the end of your journey, because I would love to see you learn to lift like you said and succeed in whatever you choose to do. Take care and I do hope to see you again ✌

Lisa 1 year ago

Fantastic experience: Found Golden State after doing an online search, I was looking for a new gym with a good community of people. I definitely found that with Golden State. I was at a point in my life where I had put on a little extra weight and didn't have a lot of motivation to push myself. I needed good solid coaching for weightlifting and the consistency of 3 to 4 workouts a week GS feels like a second family to me now. Crossfit classes are now part of my weekly routine, and i have definitely seen an improvement in my overall physical ability & body composition. I am part of the "morning crew ", love coach Eddie!

Golden State CrossFit

Eddie's AM Crew So awesome. Thank you for your review Lisa. These are all wonderful things to read and to be labeled a second family, means more than you know!

Bailey Garbarino 1 year ago

Fantastic experience: Prior to GSC during 2020-2021, my workouts and motivation were really lacking. I started attending GSC over a year ago and figured I would just start with going 3 days a week. After the first month, I felt motivated again, liked the coaching and classes, and was excited to change to an unlimited plan so I could go as much as I wanted! It’s become my routine again, which feels really good. If you are in the area and looking for a great gym, come check it out!

Golden State CrossFit

Bailey G! Thank you so much for the awesome review. We are so happy you chose GSC as your home box. Has it been over a year already? It's like that when you're killing classes consistently!

Christina Damian 1 year ago

Fantastic experience: Golden State CrossFit has helped me on my health journey tremendously so far. Because of the easy to follow accountability nutrition plan, my monthly body scans, and my individualized home workouts, I’ve lost over 10 pounds so far this year. The personal attention and detailed orientated membership is priceless. Couldn’t have asked for better coaches to support me on my health journey!

Golden State CrossFit

Hello Christina! We are so thrilled you chose us to support you in your health journey. We are stoked watching the progress you have made and the dedication you put in everyday. Looking forward to the future and can't wait to see your milestone executed.

Fabian Martinez 1 year ago

Fantastic experience: This place is seriously awesome, you guys! It definitely has a strong community and everyone is there to help out others. You're not just going in and getting a workout done. Instead, you're hanging out with a bunch of friends while also doing really fun physical challenges and moving heavy things . The coaches and the other members are ridiculously friendly and encouraging. In addition to the training you get from the coaches, you'll always be getting helpful advice and pointers from everyone else as well.

Golden State CrossFit

I love this Fabian! It has been a pleasure for all us having you in class. Thank you so much for trusting us and always walking in with a smile on your face.

Sofia Arias 1 year ago

Fantastic experience: GSC may be the most welcoming and supportive gym environment I ever been around . No matter how life hits you the coaches have your back and your best interest at heart . Also, I can’t express this enough but I appreciate how clean the gym is and how on schedule they run the classes .

Golden State CrossFit

Sofia! We are so thankful for your trust in us and continued support over the last 6 years. You are amazing!

Veronica Peña 1 year ago

Fantastic experience: I really like the structure they manage in this place for their work outs. They are always aware of postures & encourages us to go for more if they see us capable of doing so. I really enjoy the friendly, kindness, supportive atmosphere of all the coaches. Their attitude is always super positive. I love being part of these team.

Hey Jerry! We are so happy you chose us to bring your fitness to a new level. 4am sessions are no joke! We hope to see you back soon.

Angela Ortiz 2 years ago

Fantastic experience: This is the most consistent I have ever been in my fitness . When I thought about joining CrossFit, I though it would not work for me as a beginner in fitness, coach Chawg told me CrossFit is for any levels, not to let the "CrossFit Athlete's " intimidate me. Once I joined Golden State CrossFit I just fell in love with CrossFit and never looked back to a regular gym! All the coaches at Golden State CrossFit; Chawg, Jamesia, Eddie, Christy and Zack are all Amazing !! They actually care about every individual, they make you feel like family at Golden State CrossFit!

Golden State CrossFit

Thank you so very much Angie!! We’re very excited & lucky to have you. We can’t wait to watch you grow on your health and wellness journey! We’re always here for you.

Michael Vicencio 3 years ago

Fantastic experience: GSCF is an absolute gem. As someone who has no experience in weightlifting or any formal exercise training, all the coaches have been incredibly supportive, knowledgeable, and friendly. They place great emphasis and importance on proper form and technique, which takes a lot of the anxiety away especially from a beginner like me. They also scale any exercise when needed to accommodate your level of strength or any injuries, so no sweat if you cannot lift a certain weight or do an exercise because there's other alternatives. I really appreciate how the classes are not too big (8-10max) so they are able to keep an eye out to make sure we're doing the exercises correctly and provide tips and guidance along the way. The overall atmosphere is very welcoming with great people who cheer you on and support you. The workouts are definitely challenging, but they're also fun and different which makes it exciting. I definitely feel motivated to continue with my fitness journey and Golden State CrossFit is the place to be, to help me reach my goals. Thank you coaches for being awesome!

Golden State CrossFit

Wow Michael! Thank you so much for this amazing review. I can't believe it's been more than a year of coaching you! We are so happy to be part of your training journey.

Fantastic experience: The best people and my favorite gym! These coaches are rock solid, caring individuals.This is THE most consistent I have EVER been with my fitness. As a beginner I was so nervous for my first PT and first group class but the team at Golden State Crossfit made it very welcoming. It's not easy but EVERY time I leave the gym I'm SO glad I signed up. Thank you ALL so much!

Golden State CrossFit

Thank you so much for the kind words and very happy to have you a part of the GSC family.

Julie Morrow 3 years ago

Fantastic experience: I joined Golden State CrossFit a couple weeks ago. I hadn't been working out since Covid started so I definitely felt like I was starting from the beginning again. I had 4 personal training sessions with Chawg before starting the actual CrossFit classes. This was great because he really focused of my form and technique. Christy is a great resource with regards to nutrition. She has motivated me to keep on track and to fuel and hydrate my body properly. And she is so nice! The coaches for the classes are awesome - both Jamesia and Zachary give great tips and step by step direction. They also can scale/ modify the exercises when you are first starting so it is not too hard or overwhelming. They definitely have a positive team vibe and everyone supports and cheers each other on! Give it a try, I know you'll love it!

Golden State CrossFit

Hey Julie! Thank you SO much for this review! We are so happy and lucky to have you at Golden State Crossfit and Nutrition. We can not wait for the awesome positive healthy lifestyle changes and results to show and appreciate your support! <3

Kerri Jones 4 years ago

Fantastic experience: I'm a travel nurse from Ga that was in the area for a few months and needed a box while I was in town. Not only did Golden State Crossfit take me in, but I believe that I've made life long friends. The coaches have great energy and everyone is very welcoming. I can't wait until I'm in the east bay again - I know where I'll be doing my WODs!

Golden State CrossFit

Thank you Kerri! We love having your high energy at GSC and hope we get to see you again. We appreciate your support and are grateful you picked us!
