After being bullied at school because of his weight Sirtaj Rahman felt unconfident and unhappy.
But after deciding to transform his waistline and his life aged 18, doors have opened which he could never have imagined.
Mr Rahman, who is now 32 set up his own sports nutrition and clothing business Pumping Iron in Friars Square, and also works in the centre as a security guard and as head doorman at Aylesbury’s Fever nightclub.
And later this month he will compete in the UKBFF London and South East Championships in Hayes, in a bid to win a title.
He said: “I’ve been doing this for about 12 years, when I was younger I was really fat and I used to get bullied at school, the kids used to call me names like fat sausage and things like that.
“I used to weigh 15 or 16 stones in fat and my waist was a 36.
“The one day I looked in the mirror and realised that I just looked horrible and everything changed. I wouldn’t be doing any of things I am doing now if it wasn’t for that moment.”
He added: “It was amazing for my confidence, and I went from being a no one to a someone, it’s been really nice to support other people who went through the same things too.
“It not just about going on a diet, it’s about changing how you do things forever.”
After deciding to get fit Mr Rahman enlisted the help of Tony at Bodyflex Gym.
And to get ready for the Hayes competition he has been training under the supervision of Eddie Abbew, a British number one bodybuilder who runs the Olympian Gym at The Marlowes Shopping Centre in Hemel Hempstead.
Speaking about his training Mr Rahman said: “Eddie is getting me ready for it and it’s going really well.
“He’s a really good guy and his support has been great.
“I’ve been doing this for 12 years and have never done a competition before,
“I think it’s good for the customers in my shop to see that it’s run by someone who can do something like this though.
“There is two weeks to go now, and I’ve had to cut my carbs so I feel a bit weak, but it has been a great experience.”
He added: “I just want to help other people, and for people to see that they can do it too if they work hard.”
