hi all im new to this sight so i just browsing around and ths caught my eye.

Im 18 and i way around 9 stoneish i think and quite tall.
I have been trying to put ON weight so i could build my self up but it is not working.
I eat tones of junk food and some moderatly healthy food but just burn it all off in a matter of days in which i can gain weight.

Can Anyone Help?

Cheers
Jack
