We’re redefining fitness on Mercer Island.

For many, achieving their fitness can seem daunting or a nearly impossible feat. And for some who have been in the gym for years or competing in marathons and triathlons, your current training program might have become routine.

Mercer Island CrossFit is changing that.

CrossFit is by design is “broad, general, and inclusive.” That’s been our definition of fitness since day one. When we opened our doors in 2010, our aim was and always will be to introduce a workout regimen that’s suited for everyone to anyone who walked through those doors.

Our workouts are challenging for the newbie and the lifelong athlete, but we ensure that they’re also appropriately tailored to each individual’s unique needs and abilities. Each workout is thoughtfully designed so that it can be easily modified by our knowledgeable coaches right on the spot for each ability level. We know how to get you to the limits of your abilities -- that place where positive change happens.

Find out how we create fitness that’s for everyone -- and find it for yourself.

Don’t limit your challenges. Challenge your limits.

  • Because of my time at MI CrossFit the transition [to fatherhood] has been better – I sleep better (though maybe not as much), I have more energy, and I am able to focus better at work. Both my coworkers and basketball buddies all commented that I gained energy and coped remarkably well with the change (I haven’t told the basketball group my secret; I like the advantage).

  • I have been doing CrossFit twice a week for the last five months. My cycling and running have improved without sustaining any major injuries. At my age, I tend to lose fitness faster and take longer get it back after a layoff. I can’t stop now. I love it.

  • I went for a sneak peak and coach Corey was very welcoming and took the time to introduce me to the concept of CrossFit. I would rank my decision as one of the best I have made! Going 2-3 times a week has totally changed my physicality. My body has totally transformed, with muscle groups dormant for years, being active again.
