Greggs I was heavily into Muay Thai and fought on pro shows, and coached, although I no longer do it, my last fight being about 3 years ago.
I got into it at a relatively late age of around 28 or 29, and just did it causally a couple of times a week, alongside football. But eventually took myself away from football (and more importantly the pub!), and started to take it seriously and think hard about my diet and training.
Lost a stack of weight and got into amateur fights and then coaching in my gym at the weekends. Unfortunately had a bit of an issue with the gym where I "learned the trade", and they got heavily into the Charity White Collar Boxing thing, to the detriment of the hardcore membership who turned up week on week, year on year, and it was time to move on.
Moved to another gym in Cov where I fought on pro shows. Also went for extended stays in Thailand living on gyms. First time went to Phuket and a large gym which had a good mix of young Thai fighters, serious western guys, and tourists. Didn't really make the most f this trip, there are a lot of distractions in Phuket!
Went to Bangkok to a serious gym in the backstreets, they were producing several champions and were a major promoter at Lumpinee Stadium, and learnt an awful lot there.
Sadly one day I just drifted away from it a bit. I wasn't 100% happy at my gym, although admittedly it was a fantastic place to get fight-ready, and it's very hard to manage the training with the extreme stress of making weight, at the same time as having a reasonable career. Also I wanted to get into mountain running (which I now do to a relatively successful level).
I was always a "thinking" fighter. Didn't really have ko power in my punches, but I knew how to score, how to off-balance an opponent and how to clinch well. This didn't always go well on UK shows as on some of the lesser shows the judging is carried out by kickboxing or mma judges, who really don't understand Muay Thai.
To the poster who suggested it may be cliquey at a Muay Thai gym, I'd disagree. People there from all walks of life and all ages. Just have to pick your gym carefully to match what you want. I had issues at my first gym and it was sad to leave, but still have many friends from there and I'm eternally grateful for the path it set me on.
If you want any advice on gyms, fighting, scoring, or anything related then feel free to ask.....
