Barbell Curls
One of the great biceps builders, however, if you find the straight bar uncomfortable on your wrists, simply pick up a curl bar, namely the patented EZ Bar. For all-intents-and-purposes, it's exactly the same exercise, but the angled bar may just prove more comfortable for use.
As mentioned on many other biceps exercise demonstration pages, your shoulder muscles act as a stabilizer during an arm curl movement, therefore, keep your shoulder STABLE! Do not cheat yourself by swinging the weight, simply lesson the weight and perform with good form. If your shoulder muscles are fatigued, and that's why you're struggling, jump on a preacher bench.
