⭐️⭐️This is the best workout in the bay ⭐️⭐️I’ve been physically active my whole life cycling through various different activities like CrossFit, gymnastics, boot camps, and dance. FNS is a real gem — a very thoughtful, science-backed blend of cardio, HIIT, & strength work that’s proven to be extremely effective. You’ll rarely do the same workout twice. It’s a massive space and well-run operation with world class coaches. I love that workouts often include outdoor time + the early classes include a beautiful sunrise. Best way to start the day is at FNS. Shoutouts to Coach Brendan for his early morning motivation.


I honestly cannot recommend this gym more highly. I am absolutely in love with this gym and the coaches who make it what it is. I have been weight training for a long time, about 12 years in my life, and recently took about a year off/gained a bunch of weight/wasn’t focused on my health. I moved up to the bay area from OC for work and tried one or two other gyms before finally finding the gem that is FNS. They have a wide range of class times ranging from 5am-630pm and there are plenty of them. The classes are challenging, stations organized for you, and they move at just a quick enough pace that doesn’t allow you to stop and think about cheating yourself out of a great workout! Lol. You gotta move! Every single coach I’ve had at a different class time has been enthusiastic, supportive, so kind, friendly, and most importantly long term goals/health/safety focused. It’s just a place you WANT to be, not somewhere you feel you HAVE to go. Shout out to everybody I’ve met there so far or who has coached me: Coaches Mark, Andrew, Matt, Michael, Pam, Eurees, Brendan, Emily, and of course owner and coach Brian whom I just met today. They’re all seriously amazing. I’m sure there are more great people I just haven’t met yet. I look forward to living my next fitness chapter and rebuilding myself as an FNS member! I can’t wait to be here for a very long time. Thank you FNS for making me excited to be my fittest and healthiest self again.


I’ve been a member at FNS for almost 10 years and it’s my home away from home. The workouts are great but what makes this place really special are the people. The coaches actually know and care about not only your fitness goals, but your personal life as well. Coach Brian has worked hard to create a safe and inclusive environment where you leave feeling empowered and part of a team. The community is top notch and I’ve met some of the greatest people through FNS.


FNS training center is the ultimate gym experience. The coaches and staff are amazing , dedicated individuals who listen to your goals and help you accomplish it. Variety of classes offer the perfect opportunity to customize your own fitness .i highly recommend it to everyone regardless of their fitness level.


STEPHANIE is a real treasure. Very knowledgeable, always spends time in advance to prepare for my training and follows my nutrition, results, etc... She always pushes me to use my whole potential meanwhile taking care of my postpartum and physical issues. Very understanding and supporting person. I can't tell enough about her. I really like the facility and other staff too.


I’ve always struggled to have a consistent workout routine. I love that Brian holds me accountable in the most encouraging way. There is a sense of family when joining this gym. I also love that the workouts are streamed live from my home. No excuses with how convenient the streaming feature is. :)


I LOVE FNS!!! Discovered Brian Nuñez through Instagram, where I joined his live classes every Friday. ( I was looking forward to Fridays:) and after I decided to join his team on AMAZING FNS platform. After only a month of guided Zoom Classes I improved my running speed and strength performance up to 40%. Whoever struggles with motivation to make that first move, FNS is the place for you. You will be working out with the team of enthusiastic professionals just from your home at the time that works best for you.Bonus, FNS Platform is not focused only on Workouts but has a lot of useful information on Nutrition, Health, Inspirational thoughts.. etc.I WOULD RECOMMEND IT TO ANYONE, doesn't matter what is your fitness level, location or time zone.Thank you FNS for all high energy you bring every morning... and for holding us accountable.


I came here for a fundraising workout to honor a gym friend who had passed away. He used to work out occasionally at this gym and they allowed the group to use the facilities for the fundraiser activities.All the staff there were extremely friendly and compassionate about our friend’s circumstance. They treated us like a gym family.I also had a wonderful thorough workout like I never had before. It felt like a cross between personal training meets boot camp in a group environment where you team up with partners and give each other support.It was a “feel good” while “getting fitter” environment.I will be back for some sessions later this Spring!


This place has transformed my fitness in many ways. The owner/coach Brian is so amazing and friendly. I have gone to the group classes which are awesome and fun and had 1:1 training with Kim who is AMAZING! Within a few weeks, I have lost fat, gained muscle and become much stronger. The equipment is really good and all the coaches, regardless of whether they teach you or not are super friendly and motivating. Love the culture this place has!


Great facility. Wonderful class. High energy. Engaging. Motivational. Nice people (so far, was just my first class). I felt very welcome. Like the free training room. The classroom equipment was in great condition and plenty of room to get a great work out in.Great and supportive coach. I liked that even with everything that was going on (with the people) he still fixed my form a couple of times. I appreciate that. Also, no high pressure sale to get me to sign up.
