Shoulder Exercises, Sculpt and Tighten (cont.)

In addition, people tend to hold stress in their shoulders, pulling them up and creating tension, says Calabrese.

Balance Is Important

The most important thing to consider when working the shoulder, says Gunning, is to work all parts of the shoulder evenly.

"Overdevelopment of the anterior deltoid and chest gives you that hunched over kind of look," says Gunning, who manages Unilever Cosmetics International's corporate fitness center.

Besides working in balance, there are other considerations when training the shoulder, says Calabrese.

"The shoulder is a really vulnerable joint," she says. "It's a ball and socket joint but it's floating in the socket, held by ligaments and tendons."

Inherently, that makes the shoulder more at risk for injury.

"The shoulder is hypermobile and can easily be dislocated. It is easy to put it into a susceptible position."

When working the shoulder with free weights as in a lateral raise, the weight is far from the joint moving it, which can create instability.

"As the poundage that you're holding gets farther away from the joint your working, there is greater risk of injury," says Gunning.

The heavier the weight, the more difficult it is to keep a joint like the shoulder stable. Lighter weights are a much better choice.

"Muscles in the shoulder are small," says Gunning, "so weights should be pretty light."

Another weak part of the shoulder for many people is the rotator cuff. It is prone to injury from overuse, she says.

"People should be actively training the rotator with internal and external rotation," Gunning says. This can be done with tubing that is attached to something to hold its tension. The arm would begin bent at the elbow and holding one end of the tubing pull the forearm toward you for internal rotation and away for external rotation.

"People pay more attention to the vanity exercises that actually build the muscles but the tendons and ligaments need to be strengthened too," Gunning says.

Another reason to train shoulders is that these muscles are assistors in just about any upper body exercise, including push-ups, bicep curls, and chest presses, Calabrese explains.

Calabrese and Gunning offer these safety tips:

"Start from a neutral position, relaxed with shoulders down. Start out with a resistance that will allow you to perform the move properly," says Calabrese.

She suggests using a mirror to track and maintain proper alignment.

"Sometimes you're so misaligned that you get used to holding your body the wrong way."

"If it feels awkward, sometimes you're so misaligned that you get used to holding your body the wrong way," says Calabrese. "A mirror can help. Keep resetting yourself and realigning yourself and focus on staying relaxed."

Focus on the concentric (shortening) and eccentric (lengthening) equally, she explains. And always work slowly -- two to three seconds in each direction.
