Interesting point here. I work in a gym and am aware of loadsa guys who have had implants - like pecs, calfs and stuff like this guy here (abs etc). One guy went away six months ago for three weeks and came back with a truly heroic pair of tits. I know they have to be implants but no-one else does who works out regularly at the gym. And you know what - unless anyone knows about them, and is told, then people just think they are naturally muscular, ripped or whatever.
Don't take any notice of some grainy photograph - that kind of shot would make the best of naturally worked abs look duff! Those who comment about someone's looks on the basis of a bad photograph do not understand the nature of image. Ever stopped to think what they do on the covers of all these men's mags? If the guys haven't had implants or surgery, then a lot of it is faked by photography, photoshop etc. None of it just photographed naturally on a cellphone in someone's bathroom in bad lighting just after an op.
