You are right. I do look like a stick in clothes but the way i look shirtless now topples the way i looked at 240 in clothes. I'd rather look good with 150lbs of lean muscle then 220 of fat.
you have abs. that's all. and there are people twice your size with abs. and there are people who aren't natty that are huge with abs. so at the end of the day you're a twig that gets dwarfed by the guys on underwear packaging and you're hating on a guy who has more muscle tissue in his leg than you have in your body.
at 150 pounds, your entire weight is taken up by bones, organs, and skin. i go to the gym and i see 30 or 40 guys flashing abs and showing veins on their arms/shoulders. the number capable of putting five plates on any lift? now you're down to three, and we all know each other by now.
you go to a bar and the sub-160 pound guys end up looking like frail little children.
