I eat whatever I want, and exercise none 
Thanks Adam... rub it in why don't you... my wife is just like that though... eat chocolates and stuff, but she is a vego... lol... anyway, she can get one of those girls six packs from doing situps for a day... 
i am attempting to gain 12kg in 6 months. would see me get into the mid 70's. so far put on 3kg in 2 weeks though.
i didnt think i really had the time to go to the gym, but after a bit of juggling of it im now going 5 times a week.
Weight gain hey? Good stuff.. taking protein? Should help
I used to gym like crazy back in my uni days... I think I was about 75kg, mostly muscle... then got married, full time work, not much time for anything else, so lost muscle and now I'm low 70s with almost no muscle...
But I can get pretty big arms quite easily... just a week of working my arms out and they are good again, chest too... but no abs...
