Rumble Boxing Long Beach is a boxing-inspired fitness boutique that combines the science of boxing with the transformative power of strength training. Each class is a 45-minute, high-octane 10 round fight with HIIT, metabolic conditioning, and the benefits of cardio in one seamless class. No two workouts are the same—so you'll never get bored—and the classes are beginner friendly so you can rumble at your own pace. ** Located on the Marina side next to Active Culture.
Started on ClassPass and ultimately switched to a membership—love that I don’t have to sacrifice boxing or strength-training for the other, the class schedule is varied in a way to create a cohesive workout routine, and that they actually teach technique and defense, rather than just approaching boxing as cardio. Rumble takes away all the stress of having to plan out my workout regime. 😅

came across Rumble Boxing through an ad, took their free introduction class and was hooked- no pun intended. I alternate between morning and afternoon classes, but regardless of what time of day I come in at, I ALWAYS leave drenched in sweat with a smile on my face, it's so much more than a workout class and I'm grateful I dropped in when I did!

Kari W/k is hands-down one of the best trainers at Rumble. . . She combines a deep knowledge of boxing with a fantastic energy that makes every class a blast. . . It's rare to find someone who is so skilled and genuinely passionate about teaching others. . . She creates a fun and welcoming environment where you can learn proper technique and push yourself, all while having a great time. . .
