    Her husband, Rob, the other co-owner, became my coach and trained me for my first powerlifting meet.

    I've tried working out at home, didn't work because I can't motivate myself. I've tried joining…read moreother gyms and still couldn't muster the discipline to push myself where I wanted to be physically. I had never tried CrossFit because I didn't think I had the "personality type" for it. It turns out there is no type. All you have to do is show up, listen, and do your best. The coaches and regulars have been nothing but supportive and encouraging. I'm a total beginner and I'm having so much fun. I feel physically stronger and mentally healthier. My performance at work and in my primary sport have improved as well. It's not just the workout, it's the community of people that keeps me coming back.

    The owner takes pride in the shop. That much is clear. Equinox and orangetheory are great, no shade…read moretheir way, but they don't have anywhere near the heart and soul that this gym holds. From before class starts, you're greeted with open arms. A strong hello and a "you ready to have a good time today?" is a core part of beginning my workout. Speaking of workout, you will get one here. But not a one size fits all, more is more type mentality. The coaches take the time to explain each and every movement from basic positioning all the way down to the nitty gritty of myosin/trypsin bonding and posterior chain theory for Olympic lifts. You will not be disappointed with the attention you receive during the workout. Coaches don't shove everyone through the same gauntlet day in and day out to see if you can "hang." The workout is shared amongst the group and modified according to each and every athlete's strength level, experience, and current physical limitations. This way, the only person you're really fighting against, is the one you're used to, yourself. Consistent, small bite-sized gains are what add up to a whole new you, not a silver bullet and snake oil. You want to make your life better? Let Seismic CrossFit, located in what I feel to be the epicenter of Sonoma County, make a plan and don't worry, you'll do the heavy lifting.
