The single arm cable curl is a killer bicep isolation exercise that works the biceps through a full range of motion. Right from the fully stretched position, all the way through to the peak bicep contraction. You can do this exercise using the low pulley of the cable cross over station. Step a couple feet away from the weight stack to pre-stretch the biceps. Then curl all the way up for a full peak contraction in the bicep muscles.
