Standing curls are the way to go. Barbell curls and standing hammers. I would also have to see what you are currently lifting weight wise too.

Incline DB curls work great too!
If your wanting your arms to get bigger you need to start worrying more about your triceps rather than biceps. Biceps are made up of predominately slow twitch muscle fibers which tend to develop slower. I'm not saying to disregard the bicep muscle; I would just give more attention to your triceps.Originally Posted by LastResort04
