When it comes to training biceps, a little instruction goes a long way. Many people gravitate toward the path of least resistance. That may be using dumbells improperly, using only a straight bar, or just using overall poor form.

But the biceps muscles don't only flex the forearm. They also supinate the forearm and hand. Notice how the biceps peak changes with the position of the hand during the exercise.
