Hey, I’m Tom!
I started training kickboxing less than 5 years ago. I won my first National Championship within 6 months and I was competing internationally for Britain within 9 months.
I started coaching very early on and realised two things: I love coaching and I seem to have a knack for helping others learn kickboxing. I’ve since won multiple national championships at the highest level and have competed internationally for the GB Team twice.
​
I have over 4 years coaching experience and have coached multiple national champions, some even winning their title within 6 months of training.
My goal for kickboxing is to become a K-1 World Champion and teach our students everything I learn along the way. and teach our students everything I learn along the way.

Hey, I’m Alannah!
I have been involved in martial arts since I was 6 years old! When I was around 15 I started coaching classes as a senior member of the club. At this time I also started competing in kickboxing.
Since then, I have won 3 ECKA Grand Prix, as well as winning the ECKA Nationals 3 times, and have competed for GB in the European Games and have won multiple British Championships in many disciplines, including most recently the WAKO K-1 British Championships.
​
I have dedicated my life to sport, completing multiple qualifications in sports exercise science and even completing a Masters (Msc) in Strength and Conditioning. I am a highly qualified Combat Sports Strength and Conditioning Coach and Personal Trainer. I am also a fully qualified Yoga Instructor and I too plan to become a K-1 World Champion.
