Problem with bi,s please help

Hey bros i need some help in figuring this out nobody i know can explain this to me. Whenever i do curls of any type i never get a burn in my biceps the only place i get a burn is in my shoulder i make sure they are back with my elbows out but nothing seems to work i even do concentrated curls and the same thing im getting real pissed ive tried everything please reply any suggestions our comments would be greatly appreciated:unsure: :cry:

elbows shouldn't be out...elbows should be tight up against the body. Picture yourself with a pin in your elbows holding your arms in place and only your forearms can move..understand what I am saying. When the elbows flair out you are recruiting other muscles to help you.

Also make sure you slow your reps down.
