We then decided to use him as our personal trainer, and we couldn't be happier with our decision. His in-depth knowledge of human anatomy and how each muscle works and is connected to another part has allowed us to progress in a way not to over strain our body yet push us to the limit every time we train with him. Since joining the gym over a year ago, he has added a cold plunge and a regular sauna. Chris is hands-on and is proud of the gym facility he has created. We have referred many friends to him, and everybody loves Chris.

So I started going to RVC back in February, and in just these few short months it's had a huge…read moreimpact in my life. I'm already much more confident in how I look and in my fitness levels. I'd only started lifting weights about a year before joining, so I was basically a complete novice when I joined. But the scalability of the workouts made it so I could get an awesome workout while the coaches helped me to learn what I was doing. The owners (Nick and Steph) and the rest of the coaches are all really helpful and have awesome vibes. They are quick to correct you when you're not doing a movement properly, which personally makes me much more comfortable about avoiding injury. Class sizes are VERY reasonable - I have very rarely felt overcrowded in a class. In the end, joining RVC may be the best thing I've done for myself in recent history. The consistent exercise has not only helped me start looking better at the beach, but it's helped my overall mood and confidence. And you really can't beat that amazing post-workout feeling that you get with crossfit.

They create such a great learning environment for kids. The instructors teach excellent techniques in a way that is engaging, supportive, and age-appropriate, while also maintaining high standards. The school does a wonderful job of making it both safe and fun, and it is filled with so many great kids. The owners are clearly highly invested in making it a great school, and that really shows in every aspect of the experience. The space is always clean, it is well priced, and it truly feels like a worthwhile investment in our children's self-discipline, self-defense, and confidence.

It's a perfect addition to my weekly split and always manages to remind me of muscles I either haven't used in a while or forgot existed haha.

I also book through ClassPass and have found it to be really reliable for getting into classes here. Overall, a great studio if you're looking for a challenging, effective workout with consistently great instruction.

I've been going to X-Core in San Anselmo ever since I moved to the area, and it's quickly become…read moreone of my favorite places to work out. The machines are all new and glide really smoothly, which makes the workouts feel great even when they're tough. Every class I've taken so far has been challenging, but in the best way possible--definitely leaves you feeling stronger. The location is really nice, kind of tucked away in a peaceful spot. Parking is the only thing worth mentioning: if you park on the street right outside, you do have to pay, but the lot directly next to the studio is free, and there's also a big lot across the street, so it usually works out fine. As for the classes, I appreciate that some instructors will correct your form if you're not quite in the right position or could enhance it. Not every teacher does it, but the ones who do are probably helping in the long run--it keeps you from getting hurt and makes sure you're getting the most out of the workout. Overall, X-Core has been such a great spot since moving here. Highly recommend it if you're looking for something challenging but supportive!

I believe in giving folks chances, but this was the third time of flaking and at this point I asked for my money back. He was ok with that and claimed he'd send me a check. Then a week went by. Then two. Then two more. He said it "got lost in the mail"--I waited another month. He still claimed he'd drop by with it and he never did.

In the pandemic days, it was the motivation to move my body when I just wanted to lay down all day. As I made incremental improvements and started moving regularly, the focus shifted to other aspects of my life that were related to movement: nutrition and sleep The important questions started-- why am I showing up to my workouts exhausted? Am I sleeping enough? How do I juggle the many different aspects of my life-- personal, work, caregiving, networking, etc? Am I eating enough? Am I eating regularly? Why do I go from 0 to 100 and go from not working out at all to workout out so much I could potentially get injured? We also focused on different types of movement: mobility, strength training, working on the areas of my body like my back and wrists that had sensitivities, stretching, and setting me up for success for things like run club. I learned about hormones and having my life style be adjusted to my menstruation cycle (more difficult strength training workouts during ovulation, focus on stretching and walking during luteal phase) It has been an incredibly challenging journey to face all of these aspects of my life and have these mindset shifts day by day and now year by year, but I know that I have Mari cheering me on and by my side every step of the journey to guide and support me.
