What are some good peak bicep lifts?

[Big Dane]

Do some preacher curls, incline dumbell curls, and some heavy barbell curls and good to go. As soon as you can see the vein in your biceps all the time (not just when lifting) you will see the true shape of your biceps. You may need to drop some bf to get to this point.

Now that I think about it my arms bes responded to 21's and cable curls done under strict form as i come to the end of an arm workout got great pumps. I know arms arnt my strong point and Ive got a long way to go before im happy with them but might be worth you giving them a shot.
