    I’ve been going to KOBOX for more than 6 months now, and it’s been brilliant! The trainers and staff are so welcoming and full of energy, which makes every session something to look forward to. The workouts are tough but fun, and the atmosphere in the studio is second to none. I’ve been going 3-4 times a week before work, and it’s become a big part of my routine.

    Special shoutout to the amazing staff, Eni and Aaron, who are always so helpful and friendly, and to the brilliant trainers Mikey, Kieran, Kaelyn, and Wayne, who really know how to push you while keeping the sessions fun and engaging.

    I couldn’t recommend KOBOX more – if you’re after a fun and challenging way to stay fit, this is the place to go!

    Best place ever. Best tutors, classes and the reception team are absolutely golden to this place. Their shakes are ace too and great value to other places locally. If you have never visited before I highly recommend you book a class ASAP!!!

    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!

    Love KOBOX. Been going for almost a year and loved every visit. All the instructors are amazing but Billy, Louise, Ignacio and Joe Frost are out of this world.
