What they dont know is that actully hyper extends your arm. It usually causes lots of pain in the elbow and shoulder area. The trick is to reduce the range that you lift in. At the bottom keep your arm slightly bent, look at your arm when its relaxed it hangs in the slightly bent position. At the top try and hit the chest area just, one or two inches above the nipple line, about center chest. You may not think thats high enough but the biceps pull the wrist toward the shoulder area so taking it to your chin doesnt help do anything but move your shoulder. This will keep constant tension on the biceps and help reduce the pain. Do this on all the tricep exercises too.
