This made me laugh today, now you can get specific surgery to sculpt a six-pack!
Mind you, it won’t be much good to the ‘skinny, but I don’t want to bulk, I just want muscles and a six-pack’ brigade, as it says you have to have SOME fat to start with for the technique to work lol!
that looks shit. at least on them befor and after picture. he might as well have had the lines tattooed on his belly, it would have looked the same.
there is no curve to the lines, it just looks like the profile of mortar joints in brickwork.
