I love the experience of a smaller, independent gym. The owner, David, & trainers are experts and…read morewelcoming. The classes are challenging and fun and I know that if I show up, I'll get a great workout. I have noticed a difference in my body and I'm excited to keep it up. Outside of the gym I'm noticing that my running is improving. I've shaved almost a minute off my mile since I started training with David, even though that wasn't something I was specifically training for. When I broke my arm, I was so bummed that I wouldn't be able to work out. But David encouraged me to go to class and modified my workouts. My Ortho Dr. & Physical therapist were amazed how quickly I healed. The Dr told me that being active promotes blood flow and speeds up healing. It worked, I only missed a week from the gym and could put weight on my arm after 4 months! David's mission is to bring together a community of healthy and happy people through fitness. He and his team train in a personalized way that allows every person to be in their best shape because they believe that everyone can be an athlete. I personally believe that the owner of a gym is a huge reflection on the gym and its direction. With David's friendly demeanor, knowledge of physical fitness, and ambition to take the gym to the next level to further the quality of lives through diet and physical movement.

I went there with a friend around 11:20 am on a Sunday, and David was already there with few people , getting ready to start the session at 11:30. He charged me only $10, and gave us a small discount for my friend, and charged him only $8. In the past , I had minor IT-band syndrome , and after mentioning that to David, he showed extreme knowledge of the human body, and explained to me exactly what exercise I should, and shouldn't do. The workout was intense and my body felt sore then next day , which logically is I great result from the hour long workout we had ;) Thank you David, and keep doing what you do, because you are really good at it !

He has lots of information to share and is a speedy talker-- keeps you on your toes with fitness and listening. The space is small but efficient. Two rowing machine, two bikes, a punching bag, free weights, a weight rack, chin up bar, and a few more items. Billy has a whole fitness emphasis (nutrition, strength/resistance training and cardio). He was great at listening to our goals and asking qualifying questions to be sure he understood. He seems like a great encourager, while still motivating and pushing you. If a smaller more personalized approach is what you are after. Check this place out. Pricing wise it varies depending on your frequency but think of this as investment in results versus a gym membership.

I first started going to Xavier abut 20 years ago. I had lapsed on my fitness and my arms and legs…read moreshowed it. They were so flabby and my formerly flat stomach was long gone. He's the only trainer that has managed to make me get up and workout at 6am. It was amazing how quickly I popped into shape by just working out with him 2 days/week and doing my assigned cardio. I looked and felt great. And we became close friends..he is like my baby brother. Fast forward to COVID. Life had moved on, I had stopped working out with Xavier but we still stayed very close. One day we were talking and he picked up something in my voice that concerned him. He didn't like it and insisted I come work out with him...outside. I didn't realize it, but guess I had a bout of depression due to the isolation and recent loss of my Mom. I was heavier than I'd ever been..194 pounds! We began working out 3 days/week and I did power walks 2x/week. In one year, I lost 20 pounds, a host of inches around my waist and arms and got my body tone back. I am now 160 pounds. That's what Xav does. He sees the real person underneath, and helps you envision and realize your true potential. All from a place of caring discipline and true joy. He loves what he does and, somehow, makes you love it too. All while achieving your end game. He is truly one of a kind..and the best!!

The facility is always clean, the equipment is modern and well-maintained, and there's plenty of space so it never feels overcrowded even during busy hours. The locker rooms are also really nice and kept in great condition. One of the highlights of this location is the staff. Everyone is friendly and welcoming, and you can tell they genuinely care about creating a good environment for members. Nick in particular stands out. He's always helpful, professional, and brings great energy to the gym. Whether it's answering questions or just making people feel welcome. Additionally, Fitness SF outperforms the local competition; five points fitness, body kinetics, and the bay club all have worse hours, higher prices, and worse equipment (significantly worse regarding five points) If you're serious about building your physique, or just want a high quality, friendly environment to work out in, this gym is right for you If you or anyone you know truly believes an alternative gym in Marin is better than Fitness SF, your IQ is most likely lower than your bench. BUT! That's ok! Switch to Fitness SF and our community and equipment will get you right, physically and mentally. I know for a fact if you come here for just one month you'll never want to switch back to your old gym. Overall, its a fantastic place to work out. Great equipment, great atmosphere, and great staff. Highly recommend it to anyone looking for a quality gym in the area. Oh and I almost forgot we've got some wonderful massage chairs for post lift relaxation.
