i know this question may have been asked before...but why am i not gaining weight??

i weight trained for 2 years (three times a week) and i have only put on 5kg in 2 years

i eat anything that i can find and i think supplyment isn't the way to go...

any reason you people can think of?

genetics

McDonald's Value Meals four times a day. And you're gonna wanna forget about that working out crap.

Maybe you metabolism is really fast? Maybe the weight you're at right now is your natural, healthy body weight and you will never gain any more unless you become unhealthy.

Your body adapts to whatever it needs to.
Its not about how much you train its about how you train.
If you can do more than 12 reps put the weight up until you can just do 8.
Push yourself, get someone to spot you and do 3 more.
High weight, low reps, shock your muscles then give them a break for a day or two.
You will have no choice but to gain muscle!
(Assuming you eat enough protein)

i already do high weight low rep...12/8/6/6/4 rep...

hmmm...i guess it's really genetics then...but i was wondering...does psychological reason affect it...since i am always depress...

thanks for the input anyway
