Aj's Gym


Welcome To Aj's gym & Kingdom fight Team Peterborough

Established in December 2020, we was proud to finally be able to open for the first time after the Covid lockdown and bring a brand new fitness facility to Yaxley, Peterborough. Originally called Kingdom Fitness & Martial Arts the initial model was as a Group Fitness, Personal Training and MMA/Muay Thai.

The set up has exploded in popularity across all areas and as a result we are currently awaiting our brand new huge unit to be finished being built and move by January 2023 where we will be a full time gym also.

We specialise in Mixed Martial Arts, Muay Thai, Personal Training and Strength and Conditioning Group Fitness Circuit Training for both adults and juniors (5+).

Our group class programming caters for all levels of ability!

Whether your a complete beginner and just starting your fitness or Martial Arts journey, or your a seasoned MMA or Muay Thai professional 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?

FAQ Arrow

You are only as old as you feel, and any progress is more progress than the person sat at home on the couch right?

All of our classes whether it be the fitness circuits, MMA, Muay Thai or Kickboxing, are catered go accommodate all levels of ability.

Do you offer memberships or pay as you go?

We offer both. Our memberships are fairly priced and you get alot for your money. Our memberships are also non contract as we believe that if people love what we offer they will stay. We also offer pay as you go for classes.
