BIGGER ARMS

Building better arms isnot just about working your triceps and biceps. Learn how to work the two "hidden" muscles within the arm for greater results in less time.

No matter how much extra time you spend trying to fill out your sleeves, the minuscule payoff at the end is never worth all the effort. There's a reason for that, although you may not want to hear it: You're exercising the wrong way.

Most guys work only about 60 percent of their arms," says Mike Brungardt, strength and conditioning coach for the San Antonio Spurs and coauthor of The Complete Book of Shoulders and Arms (HarperCollins, 1997). The reason is that the two basic arm exercises most men do, the biceps curl and the triceps press-down, only work three of the five muscles of the arm.
"The common belief is that the upper arms are made of two muscles (biceps and triceps), but they really divide into five," says Brungardt. They are the triceps, (lateral, medial and long heads), the biceps and a broad, flat sinew called the brachialis anticus, which is sandwiched between the bone and the biceps.

Most popular triceps exercises challenge the first two heads but never stimulate the long head around the inside of the arm. Big mistake, because building this portion gives your arms a wider appearance from every angle (unlike the other two, which can only be seen from the back and sides).

Developing the brachialis, meanwhile, has the same miracle effect of a saline implant inside a 34A chest. With nowhere else to go but up, the brachialis pushes against the biceps, which makes them seem larger than they actually are. Unfortunately, most conventional exercises, such as barbell, dumbbell or preacher curls, never challenge this hidden muscle. The only way to stimulate it is by curling with the hands either palms down or palms facing each other arm positions most guys never bother to try.

That's where our four-step plan can help. With Brungardt's assistance, we've devised a fast, comprehensive routine that targets all five muscles in one workout. The end result: bigger arms in less time. Because you use the biceps and triceps whenever you work your upper body, it won't take much to exhaust them, so do only three sets of the following exercises for 10 to 12 repetitions each.

For the front
Wall curl: Stand against a wall, feet shoulder-width apart. Hold a light barbell with an underhand grip by your thighs, hands shoulder-width apart. Press yourself along the wall so that your head, back, triceps and heels touch the surface. (If any of these four come off during the exercise, you're cheating, so concentrate on keeping them flat at all times.) Tuck your elbows in at your sides; then slowly curl the barbell up until your hands are by your shoulders. Flex your biceps (squeezing your muscles when they're contracted helps exhaust additional muscle fibers); then slowly lower the bar back to your thighs.

Alternating hammer curl: Sit on the end of a bench, feet flat on the floor. Hold a dumbbell in each hand, arms hanging from your sides. Turn your wrists so your palms face each other. Keeping your back straight, slowly curl the weights until your thumbs are by your shoulders. Flex your biceps; then lower the weights. On the next rep, turn your wrists so your palms face behind you. Slowly curl up until your knuckles are by your shoulders; then lower. Continue to alternate hand positions throughout the set.
