Former Corrie star Catherine Tyldesley has wowed fans in a new Instagram shot, as she showed off the results of her intensive 12-week weight loss regime.

The mum-of-one shared two side-by-side images – one of herself before starting on her exercise program back in April, and the next, today just recently (Monday).

Actress Catherine revealed that she had been working with a trainer to transform her body after an injury, and it certainly looks like it’s been paying off!

In the caption, Catherine wrote, ‘Nearly there!! This was April after my injury… vs today at almost the end of 12 week program with #EvilSteve @upfitnesslive @upfitnesswomen … super excited to continue on my fitness journey.

‘All hail #evilSteve @arooshanekonam @heynickmitchell @elliottupton πŸ™ŒπŸ»πŸ™ŒπŸ»πŸ™ŒπŸ»πŸ™ŒπŸ» feeling strong!! πŸ’ͺ🏻πŸ’ͺ🏻πŸ’ͺ🏻’

Fans were amazed by the Corrie star’s incredible transformation, commenting to praise her new physique.

One wrote, ‘You look amazing!!! But you always did… congrats on all of your accomplishments…’, and a second follower agreed, saying, ‘Looking fab well done you xx’

Catherine’s body transformation comes after the actress admitted that she almost resorted to gastric band surgery when she was a teenager, and was around a size 22.

Appearing on Loose Women, she confessed,Β “I used to be overweight and when I was a teenager my education on food wasn’t the best so I was in a desperate place and probably would have jumped on that.

“We need to target the parents as well and make sure the food they’re giving them at home is the best.

“I think when you look whatever you eat is either feeding disease or fighting it and that’s very scary.”

Last year, she also revealed to The Mirror that she now always keeps a photo of her from her teen years, when she weighed 15 stone, to motivate her into staying in control of her weight.

Catherine admitted,Β β€œWhen I look at pictures of myself from that time, it doesn’t look like me. I was a different person.

β€œI actually keep a picture from when I was big on my phone to remind myself just how far I’ve come.”
