I am 15 years and 3 months old.I started bodybuilding when I was 14.5.After a viral dieases and Maleria togather for two months my muscles got too weak that they could hardly move.After that I started bodybuilding again and after few months I found that my height wasn't growing.I had 12.5 inches biceps.I stopped weight-lifting.Then my biceps became smaller. I am 5'6.5 tall,waist 26 inches and biceps 10.5 inches.I do about 30 pull-ups and bicep-arm-curl along with benchpress(I do both of them with a little weight).I eat very healthy food too.But that isnt helping me to get large biceps. I am too skinny and have too little fat.Can anyone suggest me what to do?
