Aj's Gym



Initially established in December 2020, we was finally be able to open for the first time after the Covid lockdown in April 2021 and bring a brand new fitness facility to Yaxley, Peterborough. Originally called Kingdom Fitness & Martial Arts.

Some people think we are all about fighting. We are not at all!

We are first and foremost a private gym that offers personal training, group fitness and also private hourly booking slots where you can book the gym out for 1 hour at a time to train privately.

Along side this we also have combat classes for Juniors and Adults for Mixed Martial Arts and Kickboxing/Muay Thai

Whether you are complete beginner and just starting your fitness and/or martial arts journey, or a seasoned fighter looking to be pushed to the highest level and beyond then this is the facility for you.

Do you just do Martial Arts?

FAQ Arrow

ABSOLUTELY NOT!!! We started off as a group fitness, personal training facility and martial arts team. Due to popularity we are currently awaiting our new unit to be built and will be opening our brand new full time fitness facility from January 2023 (Subject to no building delays).

We are very proud of the success of our business and also the success of both our adults and junior Muay Thai and MMA teams. However we cater for everyone no matter what your goal is.

Am I too old or too unfit to do your classes?
