Hi everyone my name is Simon Alexander, I am a trainer at Pure Gym Thornbury.

I’ve got 3 years in the industry and a lifetime of sport and fitness knowledge I’m just itching to share with you wonderful people.

I achieved my blackbelt in Taekwondo from an early age and this is where my undying love for martial arts came from, transitioning into Muay Thai and BJJ, then full on Mixed Martial Arts from there.

If you’re looking for a Trainer that will keep your training fresh and interesting, someone that genuinely wants you to find success in your health and fitness ? Then look no further.

I will have no trouble helping aid you in achieving your goals whatever they may be through a mix of Weight Training/MMA and Boxing Based Cardio sessions/Functional Work.

So what are you waiting for ? Come give me a chat in the gym, message me on my social media or drop me an email and lets get you to the next level of your fitness journey.
