ABOUT US
A real boxing gym in Ballard, built on technique, grit and community.
REAL BOXING FIRST
K.O. Fitness isn't your average fitness studio. We're a real boxing gym that incorporates fitness — not the other way around.
Founded in Seattle's Ballard neighborhood, K.O. Fitness (also known as K.O. Fitness) was built on one belief: that authentic boxing training is the most powerful way to transform your body, sharpen your mind, and build unshakeable confidence. A lot of gyms slap "boxing" on a group fitness class. We do it differently — every program we run is rooted in the true technical art of the sport, led by coaches who live and breathe boxing.
Whether you're stepping through our doors to compete in the ring, sharpen your technique, get your kids into a program that builds discipline and character, or simply get the most intense workout of your life — you'll find what you're looking for here.
From group classes and personal training to youth development and competition prep, we serve athletes of every age and experience level. Our coaching staff doesn't just count reps — they build fighters, athletes, and stronger versions of the people who walk through our doors.
Train, Transform, Triumph.
