And it seems we're not the only ones swooning over his slimmer frame...
When we catch up with a very loved-up Arg, 27, and his girlfriend Lydia Bright, 25, over dinner in Marbella, it's clear she can hardly keep her eyes off her man.
Lydia told us: "Yes, I love his body. It's a major improvement and he's so much more confident."
But although he's trying to stick to his healthy eating and exercise plan while soaking up the Spanish sun, Arg confesses he's been indulging in a few treats recently.
"I've been on a few holidays recently so my figure isn't quite what I'd hoped it would be for Marbella. But I haven't put that much on and I'm still feeling more confident around the pool and on the beach."
Well, we think you look great Arg!
