barbell curls 21's

Are 21's a good exercise for building mass i read at different sites that they are a complete waste of time but then some sites say they are good. What do you think?

huge food intake, coupled with strength gains is an effective way to gain muscle tissue

Don't waste your time. Stick to heavy straight sets done in good form and proper nutrition.

I believe that doing big compounds lifts should be more then enough for Bi's. For ex. I use to do forearm exercies but now with heavy @$$ deadlifts without straps, my forearms are normally crying for their mommy by the time im finished.
