Our Mission:

Move Everyday

We are Seattle's fundamental movement, strength & wellness training community offering a broad-based movement education and dedicated to developing strength and conditioning in teens and physical intelligence in kids.  

Located in the center of Wallingford


Our Mission

"We don’t believe our mission is to create the next great athlete, but rather to provide longevity and durability for kids to remain physically competent and engaged for their entire lives. Our focus on teaching good movement means we increase physical literacy and instill a lifelong love of fitness that will provide a basis for a healthy life not only for them but for their children too."

- Jeff Martin, Brand X Method

“My daughter LOVES Sonic.  She comes home smiling and tells me about everything she accomplished that day.  They make it so fun! There is always music playing and the kids are smiling.  I can't recommend it enough."

-Annie, parent of 6th grade Sonic
