Arg told fans that he wants to get back into shape and he shared a picture via Instagram of his ideal new look, which was taken in April when he was on holiday in Dubai.
In the snap, where he sports a lean and trim figure alongside co-star Tommy Mallet, Arg said: "I'm getting back to this ASAP, Watch this space!!!"
During Sunday night's episode (20 March), Arg joined girlfriend Lydia Bright, her mum Debbie Douglas and friend Carol Wright on a bike ride, where he declared that he wanted to shed some weight.
"Enough's enough, I need to get this weight off once and for all," he told them, ending with a positive "hell yeah!"
Also in the episode, childhood sweethearts Arg and Lydia went house hunting in Essex. Arg said: "I want it to be a family home, a home that we can live in for the rest of our lives."
Making sure they were on the same page, Lydia replied: "A family home with a family coming in like five years.
The couple also made a pact to never break up again.
"We're proper adults now," Arg continued. "We're taking a big step forward ain't we? I'm ready."
