A few questions

[Aaron-the-builder]

I am 16 130 pounds 5'10 I just started working out a little less then a month ago where my max at the bench was 80 it is now 120 maybe a bit more. I think 40 more pounds on the bench in less then a month is good. I am improving like crazy my veins pop out alot now.

Now i need to gain some weight I felt like i needed to gain weight for 3 years now im up to shape and I want more weight to work with.

What should i do to gain more weight?
I have tried eating alot doesnt work that good.
I was thinking protein
Is there anything specific 2 look for when looking at protein?

[Big A]

Eat a good protein drink with every meal.

Only buy a whey isolate powder - all else is garbage. Be careful of cheaper whey products made to sound like isolate.
DON'T BUY MUSCLETECH! It's all overpriced, overhyped garbage.

Add maltodextrin to your protein shake and have a shake as often as you can - best if one after each meal.

You will add good quality weight with this.

And don't listed to the salesrep from the health food store - they will try to sell you the products that move the slowest because they need to sell them.
