Private Gym | Muay Thai | MMA | Personal Training | Group Fitness

Imagine being able to book a gym all to yourself to train solo or with your friends. Here thats exactly what you can do as part of your membership.

In December 2020 we started off as a Group Training, Martial Arts and Personal Training facility and since opening has exploded in popularity to a full time fitness facility alongside our very successful Kingdom Fight Team. We have become a highly established Muay Thai, Kickboxing & MMA gym for both Juniors and Adults.

September 2022 we was a finalist in the Peterborough Small Business Awards for New Small Business of the Year, and also came away with the Businessman of the Year Highly Commended Award 2022.

We are also Peterborough's only private gym where you can book hourly slots to train on your own or with your selected friends (subject to availability and members only)

With over 14 years experience in the fitness industry and over 25 years as a martial artist, and many various qualifications, you are in the safest of hands.

Private Gym & The Best equipment

Imagine being able to have the gym all to yourself for solo training or with your friends.

We are a private gym that allows members as part of their membership to book the gym via an app to have the whole gym to yourself for an hour.


Whether you want to get fit, enjoy Kickboxing/Muay Thai or MMA training as a hobby or want to join the Kingdom Fight Team to compete you are welcome.

We make sure there are no egotistical attitudes or judgemental characters.

So there's no need to worry.
