#BestHour Fitness operates two award-winning fitness kickboxing studios, located in Federal Way and Kent, Washington. We love to introduce people to kickboxing so they can experience a full-body workout that activates every single muscle in their body. There is something about going 7 rounds against a 220-pound free-standing kickboxing bag that will have you call the workout – “The Best Hour of your day!” Try a fitness kickboxing class, burn calories kickboxing , try our fitness kickboxing challenges, and invite your friends to try kickboxing. Become a fitness kickboxer.
