I had a great time at Kobox Marylebone—loved it here! The reception staff were super friendly and welcoming, and the changing rooms were clean, well-stocked, and comfortable. The class itself was run by Rochelle and Kaelyn, who were both awesome. They made sure each exercise was easy to follow and kept things fun, even when it was a pretty intense workout. I definitely worked up a sweat! The trainers seemed really passionate about what they do, and I appreciate the modern, tech-infused approach they bring to training. Would totally recommend!

Frequently asked questions

What is KOBOX?
KOBOX is no ordinary boxing club. KOBOX is 50-minute high intensity boxing classes for all fitness levels set in state-of-the-art fitness spaces where fight club meets nightclub. When the class starts the lights go down low, the sound system kicks in and the fun begins.

Every KOBOX class is broken down into two parts. For half of the class, our trainers will take you through our signature 6-punch combinations system, which will be projected on the walls or screens for you to follow. For the other half, they’ll have you working up a sweat with a range of functional training exercises, focusing on a different body part each day.

KOBOX mixes boxing technique with high intensity interval training (HIIT) for an incredible workout. Whether you’re a seasoned pro or boxing beginner, you can take the class at your own pace in your own space. It’s about working hard, sweating lots and punching life in the face, TOGETHER.
What if it's my first time at KOBOX?
If it’s your first time at KOBOX then welcome! Please arrive at least 15 minutes early and attend the class induction. In the induction the trainer will take you through each of the boxing combos and guide you on positioning and technique. They can also assist you with your hand wraps and gloves if you need some help.

If you are new to KOBOX and not there by the time the induction starts, you cannot attend class.
What happens in a typical KOBOX class?
Every KOBOX class is broken down into two parts. For half of the class, the trainer will take you through our signature 6-punch combinations system, which will be projected on the walls or screens for you to follow. For the other half, they’ll have you working up a sweat with a range of functional training exercises on ‘the wall’, focusing on a different body part each day. Each trainer runs their classes slightly differently keeping every class varied and fun.
I’ve never done boxing before, can I do KOBOX?
Yes you can! We want everyone to experience the high of a KOBOX class whatever your experience. You don’t need to have ever boxed before. Our class induction will take you through everything you need to know. And when the class starts the lights go down low and it’s just you and the bag. Everyone is welcome at KOBOX.
