Remember X Factor’s Sam Callahan? He’s looking very different these days after THIS incredible transformation
The former reality star has been described as 'inspirational' by his social media fans
SAM Callahan first hit our TV screens as a timid X Factor contestant three years ago - now he's revealed his amazing body transformation in a series of social media snaps.
Wowing his fans, the former reality star showed off his rock hard abs as he worked out in the gym.
One Instagram follower gushed: "Looking amazing babes", while another simply commented: "Inspirational."
In 2013 Sam turned heads as a cute, smiley-faced wannabe on the ITV1 singing competition.
Standing in front of judges Nicole Scherzinger, Gary Barlow and Sharon Osbourne, he performed a cover of James Blunt's You're Beautiful.
The 22-year-old has been blogging about his recent transformation and wrote in one post: "I do have a slight advantage over a lot of people in the way of muscle memory.
"If you have been following me for a while you’ll know that I have always kept myself in "decent enough" shape and there have also been times in the past where I have been very muscly and had a very low body fat percentage which means that my muscle memory will allow me to get back to that physique faster than your average Joe."
Sam added: "However, I don’t want that to discourage anyone, as the transformation you can make in a small amount of time can still be mind blowing given the right amount of commitment and work."
