At age two, Trinity Cook underwent surgery on issues caused by her rare genetic disorder, having operations on a turned eye, bowel prolapse and hernias.

The Brisbane-based local has Williams Syndrome, a mutation that sees several genes deleted, including the elastin gene on chromosome seven.

Her shortage of elastin caused a heart defect, intellectual deficiencies and distinctive facial features, but none of those things have taken away from Trinity's desire to work hard and succeed.

She began personal training at sixteen to avoid getting joint stiffness as she got older - a side effect of her condition.

'Trin had developed rounded shoulders and poor posture and urgently needed to strengthen her back and chest,' PT Angie Moore from Move.Live.Be told FEMAIL.

Trinity started with just two days a week at first, quickly falling in love with the feeling of working out and the look of her quickly toning muscles.

Two years later, her confidence soaring, the brunette, now 18, competed as a sports model with iCompete Natural in Queensland.

The organiser Jason Woodforth created a 'Physically Challenged' division especially for Trinity - and she walked away with a trophy.

'We have to train very carefully and use slow, controlled movements with lighter weights and reps than most people would use, to protect Trin's joints, soft tissue and ligaments as this is where much of the elastin deficit occurs,' Miss Moore said of her client and good friend.

'Because of this elastin deficit, Trinity's joints are more likely to hyper extend and dislocate, and over time become quite stiff if the exercises aren't performed correctly.

In a bid to prepare for her competition Trinity upped her training to three times a week, continuing to eat clean - something she actually enjoys

'I use a hands-on approach with Trinity's training, which means I am always ready to take the weight if the exercise we are doing becomes too much for her.

'We have worked a lot on her core and on strengthening the muscles in her back by doing pulldowns, chin-ups and rows to specifically improve her posture and relieve the tightness from her chest muscles.

'When Trinity first came to me, she could not perform one single hanging leg raise, now she can do well over 50.'

'I really wanted to get it right so I didn't feel like I was struggling on stage and would feel confident,' she explained

The hardest part of the preparation was learning the poses for the competition

'I would never want to quit as I love having toned muscles to look and feel as fit as possible. Exercise makes me feel happy. I love to be strong and told Ang when I started that I wanted a six pack. I was so proud of my six pack on comp day,' she said.

The hardest part of the preparation was learning the poses.

'I really wanted to get it right so I didn't feel like I was struggling on stage and would feel confident. Ang and I practiced after every training session for many weeks,' Trinity said.

Unfortunately Trinity tripped on a set of stairs at school earlier this week and broke her fibula, but even that accident won't stop her progress (pictured)

'We also went to see Jess Williams who is an ICN Posing Coach to make sure I was doing the right poses.'

'I'm going to have a big rest this week and then straight back into it! Training upper body and abs until my leg gets better,' she wrote on Instagram.
