Atlas discs, chippers, WOD’s, and good mornings. If you have no idea what we’re talking about and think we’re just naming weird phrases or pet names, then it’s time you check out CrossFit. It’s all the rage these days and it’s easy to see why. Who doesn’t want to get fit and healthy and have fun doing it? CrossFit is one fitness trend that isn’t going away any time soon which is why we think it’s awesome that Seattle-area gyms are focusing on our little ones. Read on to learn about six CrossFit gyms that are not only kid-friendly, but offer specific classes dedicated to the small crowd.


Sonic CrossFit Kids
Located in the center of Wallingford, Sonic CrossFit Kids is Seattle’s first CrossFit gym soley dedicated to kids and teens. Your little one is guaranteed not only a chance to be active, but to get a workout space and coaches devoted strictly to them! The gym is run and coached by Michelle and Ted who both grew up playing sports, exercising, and know what it means to lead a healthy lifestyle. They are both certified in Kids CrossFit and certainly know the ropes. They also employ a hands-on approach and teach that everyone should support everyone, no questions asked. Truly awesome!

Classes run on Mondays, Wednesdays, Fridays, and Saturdays at various times depending on age group. Classes are drop-in so you can show up any day you want, perfect for getting some energy out if your kiddos are feeling a little rambunctious.

Fees range from $5 for your first class to $150 for unlimited monthly classes. Psst! Don’t forget to ask about their sibling discounts!


Good to know: Sonic CrossFit Kids is located in the bright blue building down the driveway behind Kabul restaurant. Don’t park in the shared driveway, but feel free to park in Uptown Espresso’s lot or on the street. You’re welcome to hang around and watch your kiddo or go next door and grab a cuppa Joe. There is an area dedicated for parents to sit and tend to little ones not yet old enough to participate or simply watch and be astounded as your kiddo masters the art of walking like a spider. For older sibs, ages 14-18, classes will be coming soon!

You participate as a family and kids will learn the basics of CrossFit.
