Sharing a new snap of himself on Twitter, the reality star showcased his recent weight loss and fans were quick to compliment him on his new and improved physique.
One fan told Arg to "keep up the good work" as he is looking "really well", while another praised the star, commenting: "Arg you are looking really trim!"
A friend then suggested Arg was finally reaping the rewards of his boxing training lately, to which he replied: "Lol I'm trying mate!"
As well as stepping into the ring to focus on his fitness, Arg has also been spotted training with his fellow co-star Fran Parman.
Last week, Fran managed to persuade the Essex boy to join her on a morning run. And despite working up a sweat, Arg was all smiles as he posed for a post-workout selfie.
In October last year, Arg was suspended from TOWIE after his behaviour became a cause for concern.
The 27-year-old reportedly check into rehab shortly after in a bid to curb his partying ways - although Arg himself never confirmed this.
On his return to Essex, the star vowed to change his ways and start over following his treatment.
He tweeted: "It's good to finally be back in Essex. Home is where the heart is. New year coming up and a new start."
Well if Arg's latest picture is anything to go by, it looks like he is sticking to his word!
