I want to get really muscular. How many times a week should i work out?

I'm only 120 pounds. And everything i eat just
seems to do nothing to me. I'm a 18 year old guy and i want to get really
muscular. How often should i work out and what proteins should i be taking? I'm
not very good with the body building stuff or things i should and should not
eat.

And do i have to take a type of weight gainer maybe?
Work out every other day. Your body needs time to recover or you are justt
making it weaker. This is because when you weight train you break down the
muscle and your body realizes it needs to be stronger so that won't happen
again. Hae some protein such as a burger or chicken sandwich afterwards. Carbs
in things like pasta would also be good. Don't use protein pills they are pretty
much fakes and a waste of your money. Drink water beetween exercises on hot
days. You sound pretty small for 18 so I suggest eating a litttle more or if you
really are just natturally that small make sure to start out light on the
weights. Unless you are competing eat whatever sugar you want, you will still
get stronger, just not be a physicly healthy. If you don't have the time work
out three days a week, Monday, Wednesday, and Friday but every other day which
is basicly alternating 3 and 4 days a week would be best. If you work out two
days a week you will not get better but will not get worse. Hope this helps and
good luck getting stronger!
dont bother with all the protein powder crap you can buy, at your age and weight
combined your body prolly wouldnt metabolise it properly and you would be
wasting money. the best thing to do is just work out every second or third day
and eat meals that are healthy. try eat more meat and carbs bread,rice,pasta
etc, than ususal but dont go over the top. when you start seeing yourself put on
muscle then get more serious and look at a more specific diet. pushups suck, but
are awesome for putting on muscle effectively as they work most muscle groups in
the body and they dont take up too much of your time. i had a friend that went
from steven hawking looking to pretty buff in 6 months of doing up to 300
pushups every few days. gd luk
You're pretty small right now. But if you're serious about this here's my
suggestion.

Lift four days a week hitting every major muscle group once. Eat a lot of food,
but make it healthy. Try to eat five or six smaller meals, instead of 2 or 3
large meals. Of your daily caloric intake, 25% should be protein (try for 1g
protein / pound body mass), 50% should be carbs, and 25% should be from fat.
Note that 1g protein, 1g carb has 4 calories, 1g fat has 9 calories. Do high
intensity cardio at least a few times a week.

As for supplements, try GNC Whey Protein Isolate. Also, I've never used it but
I've heard great things about NO-Xplode.
