I hope he stays healthy and isn't a case of too much too soon. He is INSANELY pumped, full bodied and shredded at such a young age. Reminds me a bit of Lazar Angelov-- but Mardin may even be fuller, bigger while just as wicked shredded. Didn't end well for Lazar and I can't imagine this look is sustainable.
It's tricky because he gets more and more attention, money, and followers the crazier his body gets, but can't be that healthy.
Someone mentioned a false sense of confidence, which there is some truth to it. Moreso, I think it's building ego in someone who went from a buff teenager to a 20 year old that can break the internet by just flexing his biceps. He's in a class of his own (beyond Zyzz, beyond Jeff Seid, beyond Lazar) and he knows it.
Oh, it's nice alright lol.
(Side note: What gym allows people to workout in sandals????)
If you look like Mardin, you're allowed to do whatever you want.
