I obviously agree with the part about it improving self esteem and encouraging healthy eating (which further improves your mood and mental well being) goes without saying it will make you look better and feel better about yourself and to think otherwise would be every bit as delusional as saying hairloss doesn't matter, but in general I really can't stand that forum or any of the douchey, ultra-vain ocd people you get on there, Fred summed it up very well on the other thread.
They take it to a whole different ultra-extreme and give weight lifting in general a really bad name with all the macho, bullsht talk and boasting on those threads and avatar pic selfies of their gross, disproportionate and deformed looking bodies, one guy just has an avatar pic of his massive bicep and nothing else... I mean it's laughable and anyone totally unfamiliar with the experience of going to a gym, would surely be completely turned off the idea after reading through a few threads with these circus freakshow clowns.
Weight lifting should be a fun activity for letting off some steam when you're not too busy and have the spare time to fit it in, not some lifetime occupation or fulltime lifestyle as these guys make it out to be. A lot of the workout programs over there are stupidly over complicated too... all you need is 5 exercises ffs (bench, squat, deadlift, pull up, dips) not a whole page of useless crap exercises which will make you spend 100hours a week in the gym for very little or no additional gain.
