Rene Campbell has spent the last four years transforming herself from a petite 8.5 stone size 8 to a hulking 13.5 stone of pure muscle.
The 35-year-old works out for two hours a day, five times a week and eats a whopping 4,200 calories a day with meals of chicken, rice and vegetables as well as protein powders and vitamins.
The divorcee, from Brighton, is already the UK Bodybuilding physique female champion but has vowed to get even bigger.
Self confessed “bigorexic” Rene said: “I won't stop until I'm bigger and better - I'm totally obsessive about it.
"I look at guys in the gym who are 20 stone and think I want to be that big. I'm jealous of their size, and wish I could be as big as them.
"I love the muscular aesthetic, looking like a Greek God. It's a form of art when you think about it."
Rene admits her muscly body attracts mixed reactions from people in the street
Rene, who has size 18 shoulders and size 12 waist, admits her muscly physique attracts mixed reactions from people in the street.
She said: "I have had comments from guys saying that it's disgusting. Others say 'why would you want to subject your body to that?'
"But some people admire and respect what I do.”
Rene, who is mum to Matthew, 18, and 10-year-old Kai, says her family worry about her obsession with bodybuilding, which she admits was the reason for her marriage split.
She added: “"My parents are very supportive but I don't think my mum understands it.
"She would like me to do something a little less obsessive - but I think you've got to be obsessive to get to the top of your game.
"I've had a partner who told me in the past that they couldn't handle the bodybuilding any more.
"They gave me an ultimatum - it was the bodybuilding or them. But you've got to do what you've got to do.”
Rene aged 15, before her bodybuilding obsession took hold
As a keen sportswoman when she was younger, Rene decided to take up bodybuilding as a new challenge four years ago.
Since then she has taken part in eight competitions and recently came first in the UKBFF British Finals.
She said: "I just got into the idea of getting bigger and moving it up a notch. I like the challenge and the discipline of training.
"Winning the title in October was a dream come true. When I won the British final my mum said that's enough, just walk away from it now - but I don't intend to.”
