Trainer bio

Having been a member of commercial gyms for most of my adult life, I didn’t really catch the ‘fitness bug’ until my mid-thirties.  I was always overweight as a child and I remember the school having to ask my mum to monitor the portion size of my meals.  Being from a Chinese family this was hard as food is a big part of our culture – instead of saying ‘Hi’, we say ‘have you eaten yet?’!

The usual bad habits of drinking and junk food took over in my adult life and at my heaviest I was 18 stone.  I joined a bootcamp at the gym and stuck to the diet and saw the weight come off but what surprised me most was that I actually enjoyed it.  I started to do exercise classes like Bodypump and Boxercise and eventually started running – 5K turned into 10K which then turned into half-marathons.

Then in 2012 someone told me about Caveman Training ‘where they eat steak and nuts for breakfast’ and I was intrigued to try – how hard could it be?  I did my first class and it was the hardest thing I’d ever done – tractor tyres, sledgehammers, baseball bats, battle ropes, prowlers and lots of weights.  But every session was different setup and everyone was so friendly and supportive and I was soon addicted!


Following redundancy, I bit the bullet and studied for the qualifications required to be a Personal Trainer.  It is something I have always wanted to do and have a great passion for and Adam has kindly let me join his great team and jump on classes as a trainer.  Having been a member for many years, it is so different being on ‘the other side’ and I absolutely love it!

Being at Cave has also enabled me to tap into Adam’s wealth of knowledge of different training styles from training with icons like Charles Poliquin, Dorian Yates, Milos Sarcev, Tom Platz and Phil Learney to name a few.
