Big Biceps Now!

Add serious size to your biceps by focusing more on the smaller upper arm muscles.

By David Sandler, MS, CSCS, and Jim Stoppani, Ph.D.

When it comes to arm training, one muscle in particular always seems to hog the spotlight. The biceps brachii is the large two-headed muscle that makes up much of your upper arm, but it doesn’t work alone.

The brachialis and brachioradialis muscles, which help flex the elbow joint, also add size and shape to the pipes, though it takes a little extra manipulation to get them to grow. The brachioradialis makes up a good part of your forearm as well and will complete your arm development by adding a Popeye-like lower arm to that bulging biceps. In other words, biceps training isn’t just about training the biceps.

Arm Yourself

Most people start their biceps routine with a straight bar curl, arguably the best mass-building move there is for the bodypart. But starting there fatigues some of the smaller muscles of the arm, making it hard to get them to respond later in your routine and thus hampering long term mass gains. Although most research would argue against working smaller muscles first, this may be your best option because it stimulates all the elbow flexors and increases total muscle recruitment right out of the box.

Remember, muscles eventually get bored by the same old workout. They learn to be more efficient, and they just flat out quit growing in the absence of new challenges. By working smaller muscles first in your workout, you burn them out and require the larger muscles to work even harder to recruit more muscle fibers. And while this may seem contrary to the physiological standards for muscle expression, continual stress forces continual recruitment, which should translate into greater strength and size gains in the long run.
