Avoiding Mistakes When Training Your Arms

Some people use such herky-jerky form when they perform arm exercises that they look like people dancing under a strobe light. Keep the following tips in mind when training your arms:

• Don’t cheat. If you contort your whole body to lift the weight, you work your whole body, not your arms. Rocking back and forth is also a great way to throw out your lower back. Think about how you’ll feel explaining to your friends that you wrenched your back while exercising your arms.
• Don’t skip your wrists. Few people pine away for forearms the size of Popeye’s.
• Go easy on the elbows. Exercise captions throughout this chapter tell you to straighten your arms. This, however, doesn’t mean snapping your elbows into a fully straightened position.
• Keep your elbows still. When your elbows veer out to the side during many biceps and triceps exercises, you’re able to lift more weight. However, this is only because you have more leverage; your arms aren’t getting any stronger. When you’re doing biceps exercises such as the dumbbell reverse biceps curl, you may also have a tendency to pull your arms and elbows forward to lift the weight. You can’t avoid this extra movement completely, but keep it to a minimum.

Enjoying Strong Arms

Because we use our arms so often in daily life, we tend to take our arm muscles for granted. However, giving these muscles extra attention in the weight room really does pay off.

• Attaining real-life benefits: Your arms are the link between your upper body and the rest of the world. If your arms are weak, your larger, upper body muscles can’t work to full capacity. You’re only as strong as your weakest link. For example, the lat pulldown, a back exercise, mainly requires back strength, but weak biceps limit your ability to do this exercise. With stronger triceps, you can more effectively challenge your chest muscles in exercises such as the push-up or the bench press. Strong wrists are crucial for many weight lifting exercises and for activities outside of the gym: gripping a golf club, shelling peanuts, shuffling cards, or working at your computer keyboard without pain.
• Preventing injury: Strong arms help protect your elbows from harm. Carry around a heavy briefcase with a straight arm long enough and eventually your elbow starts to ache. With stronger arm muscles, you can haul that briefcase around longer without pain, and you’re less likely to get tennis elbow, which is inflammation of the elbow joint. Powerful arms also minimize your chances of soreness or injuries when you perform weight lifting exercises or when you lift a dumbbell, barbell, or weight plate off of a rack. Strong wrists, in particular, help you avoid carpal tunnel syndrome. Repetitive movements such as typing, scanning items at the grocery checkout, or operating the mouse of your computer can cause this painful and sometimes debilitating condition.
• The confidence factor: The feel-good factor: We tend to equate toned biceps with masculine strength. Popeye’s biceps are almost the size of his head. In women, the jury is still out. Popular opinion can’t come to a consensus on whether it prefers women with toned arms or weak arms. The bottom line is that strong arms help you to enjoy life better and toned muscles look healthy. Society’s judgment about whether men and women should have big or small muscles is likely to change with the winds of fashion, but being healthy and strong and feeling great are always positive.

Understanding Arm Muscle Basics

Your biceps muscle spans the front of your upper arm. Hang out in any gym and you’ll see people flexing these muscles in the mirror, usually when they think that nobody’s watching. The main job of your biceps (nicknamed your is or your guns) is to bend your arm; in gymspeak, this motion is called curling or flexing.
Your triceps, located directly opposite your biceps, spans the rear of your upper arm. The biceps and triceps, like many muscle groups, work together in pairs. When you squeeze your biceps, your triceps relaxes and your arm bends, and when you squeeze your triceps, your biceps relaxes and your arm straightens. Maintaining a good balance of strength in the relationship between the two muscles is important so that one muscle doesn’t dominate the other. That’s why you need to train both.
Another group of arm muscles allows your wrists to move in a variety of ways. To spare you some jargon, we’re going to refer to these as your wrist muscles. These muscles let you bend your wrist up, arch it down, twirl it in a circle, tilt it left and right, and turn your palm up or down. One of the most important jobs of the wrist muscles is to keep the wrist stable and the wrist joint flat or neutral. If your wrists are weak, the wrist muscles can bend at inopportune times (like when you’re holding a 100-pound barbell over your chest). Weak wrists also mean that you can’t get a grip — on a baseball bat, a stubborn weed, or a can of mushroom soup — and leave you prone to conditions like carpal tunnel syndrome, an inflammation of your wrist nerves.

Shoulder press machine

The shoulder press machine is a good overall shoulder exercise because it challenges all of your shoulder muscles. It also works your triceps and upper back.
Take extra caution if you’re prone to neck, elbow, or lower back problems.

Getting set
Set your seat height so the machine’s pulley is even with the middle of your shoulder. Hold on to each of the front handles. (Your palms face each other.) Pull your abdominals in tight but leave a slight, natural gap between the small of your back and the seat pad. See photo A.

The exercise
Press the handles up without locking your elbows. Lower your arms until your elbows are slightly lower than your shoulders. See photo B.

Do’s and don’ts

• DO relax your shoulders and keep them well below your ears, especially while your arms are straightened fully.
• DON’T arch your back or wiggle around in an effort to lift the weight.
  
• DON’T thrust upward with more force than necessary; this strain puts a lot of stress on your elbows.

Other options
Many shoulder machines have arms that work “independently” of each other. That is, the left and right sides aren’t connected, so each arm handles its own share of the load. If your gym has this option, we recommend that you give it a try. You’ll get the structure and support that a machine has to offer but also develop balance and uniform strength as you would with free weights.

Internal rotation

Internal rotation also targets your rotator cuff muscles and works your shoulder muscles.
Again, if these movements bother your neck, try resting your head on your outstretched arm.

Getting set
For internal rotation repetitions, switch the weight to your left hand and lie on your back. Bend your elbow so your forearm is perpendicular to the floor and your palm is facing inward.

The exercise
Lower your hand down to the floor as much as your flexibility permits, and then lift back up. Complete an equal number of repetitions with each arm. Figure 13-7 illustrates the internal rotation.

Do’s and don’ts

• DO imagine that your shoulder is the hinge of a door that’s opening and closing.
• DO perform the exercise gently and smoothly.
• DON’T tighten up your neck and face.
• DON’T throw the weight up.
• DON’T force the weight farther than your natural flexibility allows.

Other options
Traffic cop (harder): Hold a weight in both hands and stand with your feet as wide as your hips. Bend your elbows and raise your arms up to shoulder height (in the classic stick-em-up position). Keeping your elbows still, rotate your forearms down until your palms are facing behind you and then rotate back up to the start.

External rotation

External rotation focuses on your rotator cuff muscles, but these exercises also work your shoulder muscles.
If these movements bother your neck, try resting your head on your outstretched arm.

Getting set
Holding a dumbbell in your right hand, lie on the floor on your left side. Bend your right elbow to a 90-degree angle and tuck it firmly against your side so your palm faces downward. Pull your abdominals in. Bend your left elbow and rest the side of your head in your left hand or lie on your outstretched left arm.

The exercise
Keeping your right elbow glued to your side, raise your right hand as far as you comfortably can (the distance depends on your flexibility). Slowly lower the weight back toward the floor. Complete an equal number of repetitions with each arm. Figure shows the external rotation.

Do’s and don’ts

• DO imagine that your shoulder is the hinge of a door that’s opening and closing.
• DO perform the exercise gently and smoothly.
• DON’T tighten up your neck and face.
• DON’T throw the weight up.
• DON’T force the weight farther than your natural flexibility allows.

Other options
Traffic cop (harder): Hold a weight in both hands and stand with your feet as wide as your hips. Bend your elbows and raise your arms up to shoulder height (in the classic stick-em-up position). Keeping your elbows still, rotate your forearms down until your palms are facing behind you and then rotate back up to the start.

Back delt fly

The back delt fly is an excellent move for strengthening the back of the shoulders and upper back and for improving your posture.

Getting set
Hold a dumbbell in each hand and sit on the edge of a bench. Lean forward from your hips so your upper back is flat and above parallel to the floor (if you can, support your chest against your knees). Let your arms hang down so your palms are facing each other with the weights behind your calves and directly under your knees. Pull your chin back and in and draw your abdominals inward. See photo A.

The exercise
Raise your arms up and out to the sides, bending your elbows a few inches as you go until your elbows are level with your shoulders. Squeeze your shoulder blades together as you lift. Slowly lower your arms back down. See photo B.

Do’s and don’ts

• DO keep your chin tilted slightly toward your chest throughout the motion so your head and neck don’t drop forward.
• DO lean forward from your hips instead of rounding your back.
• DON’T allow the rest of your body to move as you do the exercise.

Other options

• Back delt row: Use the same starting position except orient your palms backward. As you lift the weights, you need to bend your elbows more than in the basic version.
• Cable back delt fly: If you have a history of neck pain, try the cable back delt fly version. Set the cable on the setting closest to the floor; hook up a horseshoe handle. Kneel alongside the cable tower and grasp the handle in the hand that’s farthest away from the tower. (The cable passes underneath your body.) Squeeze your shoulder blade and lift your arm up to the side, as in the basic version. Do the same number of reps with each arm.
• Standing back delt fly: Do the same exercise while standing with your feet placed as wide as your hips. Lean forward so that your torso forms a 45-degree angle with the floor. Keep your abs pulled in to protect your lower back and resist any rocking movement.
