Having teamed up with Protein World for the brand's new weight-loss collection, Holly is the latest star from the hit MTV reality show to showcase her hard efforts in the gym.
After spending the last four years embarking on a strict health and fitness regime, the 22-year-old has dropped four dress sizes and we think she's looking pretty incredible.
Slimming down form a size 16 to a size eight, it's no surprise Holly wanted to proudly flaunt her hot bod in the shots for her latest project.
In the black and white pictures, the reality star makes even her gym gear look glamorous as she poses with perfect make-up and her long locks swept into a cute fishtail plait.
Reaping the rewards from her new and improved healthy lifestyle, in one photo Holly is seen showing off her enviable tum in all its glory while sporting a crop top and leggings. In another, the brunette beauty dares to bare as she flashes her pins in a fitted white swimsuit.
After no doubt enjoying indulging over Christmas, Holly was back to working up a sweat in the gym earlier this week. And, just like her former co-star Vicky Pattison, she looked absolutely flawless in her post work-out selfie!
Just how do they do it, we'll never know!
Opening up about her weight loss over the years, Holly admitted it was Twitter trolls who gave her the kick to focus on her fitness.
Speaking to the Mail Online, she said: "With all the comments I was getting, 90 percent of them were about my weight and were commenting on how I was fat, or how I was ugly.
"It upset me at the time and did inspire me to lose it. I just wanted to work a bit harder but also to be a lot healthier."
Like her female co-stars, Holly did claim that being on Geordie Shore doesn't help when it comes to living a healthy lifestyle.
Starring in a show where there is too much drinking and plenty of drunken snacking, Holly admitted her usually strict regime was bound to slip.
"On the show if one girl's eating healthily then we'll all jump on the bandwagon, but if one of us says lets go and get a kebab we'll go and do that," she explained.
And Holly isn't the only one whipping herself back into shape now filming has finished for a while.
Last week, Charlotte Crosby showcased her recent weight loss, while Marnie Simpson has lost just over a stone embarking on her own health kick.
Meanwhile, Holly did reveal her new lifestyle and hours at the gym haven't affected her relationship with her co-star boyfriend Kyle Christie.
Gushing about her beau, she added: "He's just happy as long as I'm happy." Aww!
The pair confirmed they were officially an item during a romantic break to Tenerife in October last year. Holly first met Kyle when he joined Geordie Shore for its eighth series last summer.
