The TOWIE fellas have scrapped the 'no carbs before Marbs' diet plan in favour of Men's Health six-week, six-pack challenge.
And boy has it paid off.
Mario Falcone, James 'Arg' Argent, Ricky Rayment, Charlie King and Chris Drake are looking better than ever after following an intensive diet and fitness programme to get in shape for summer.
Each cast member followed a personalised programme to suit their individual needs and goals.

“I was in alright shape and I know my body. I knew I could smash this challenge,” he says. “Next goal for me is the Men’s Health cover. If this is what I can do in six weeks, just watch what I can do in 10.”
James 'Arg' Argent before and after
Arg, who is notorious for failing bootcamps and ditching diets, lost an incredible two stone and 10% of his body fat.
“Saying ‘no’ to booze has been tough but I love the results and I’m going to stick at it," he told Men's Health. "Look at me: the girls are going to love it, right?"

Men’s Health’s Six-Pack Challenge
Ricky, 22, quit smoking and started boxing to achieve his chiseled physique.
"The workouts were seriously intense,” he said. “I used to be in great shape, but late nights, bad food and booze made me pile on weight."
Charlie said that his new body has attracted a lot of attention. “I’ve had more screen time this series than ever and they keep asking me to take my top off, so it must have worked.”
Chris overhauled his diet and stopped drinking to lose over a stone and build a rock-solid core.
“This challenge came just at the right time for me," he said. "I never thought I’d end up with abs, I’ll tell you that for nothing.”
