We often hear that good posture is essential for good health. We recognize poor posture when we see it formed as a result of bad habits carried out over years and evident in many adults. But only few people have a real grasp of the importance and necessity of good posture.
What is posture?
Posture is the position in which we hold our bodies while standing, sitting, or lying down. Good posture is the correct alignment of body parts supported by the right amount of muscle tension against gravity. Without posture and the muscles that control it, we would simply fall to the ground.
Normally, we do not consciously maintain normal posture. Instead, certain muscles do it for us, and we don't even have to think about it. Several muscle groups, including the hamstrings and large back muscles, are critically important in maintaining good posture. While the ligaments help to hold the skeleton together, these postural muscles, when functioning properly, prevent the forces of gravity from pushing us over forward. Postural muscles also maintain our posture and balance during movement.
Why is good posture important?
Good posture helps us stand, walk, sit, and lie in positions that place the least strain on supporting muscles and ligaments during movement and weight-bearing activities.
To maintain proper posture, you need to have adequate muscle flexibility and strength, normal joint motion in the spine and other body regions, as well as efficient postural muscles that are balanced on both sides of the spine. In addition, you must recognize your postural habits at home and in the workplace and work to correct them, if necessary.
Consequences of poor posture
Poor posture can lead to excessive strain on our postural muscles and may even cause them to relax, when held in certain positions for long periods of time. For example, you can typically see this in people who bend forward at the waist for a prolonged time in the workplace. Their postural muscles are more prone to injury and back pain.
Several factors contribute to poor posture--most commonly, stress, obesity, pregnancy, weak postural muscles, abnormally tight muscles, and high-heeled shoes. In addition, decreased flexibility, a poor work environment, incorrect working posture, and unhealthy sitting and standing habits can also contribute to poor body positioning.
Can I correct my posture?
In a word, yes. Remember, however, that long-standing postural problems will typically take longer to address than short-lived ones, as often the joints have adapted to your long-standing poor posture. Conscious awareness of your own posture and knowing what posture is correct will help you consciously correct yourself. With much practice, the correct posture for standing, sitting, and lying down will gradually replace your old posture. This, in turn, will help you move toward a better and healthier body position.
Your doctor of chiropractic can assist you with proper posture, including recommending exercises to strengthen your core postural muscles. He or she can also assist you with choosing proper postures during your activities, helping reduce your risk of injury.

How do I sit properly?
How do I stand properly?
What is the proper lying position?
"Stand up straight." That's timeless advice we've probably all heard at one time or another. It's worth heeding. Good posture is important to balance: by standing up straight, you center your weight over your feet. This also helps you maintain correct form while exercising, which results in fewer injuries and greater gains. And working on balance can even strengthen your abilities in tennis, golf, running, dancing, skiing — and just about any other sport or activity.
Not an athlete? It still pays to have good balance. Just walking across the floor or down the block requires good balance. So do rising from a chair, going up and down stairs, toting packages, and even turning to look behind you.
Poor posture isn't necessarily a bad habit, either. Physical reasons for poor posture include:
The good news: You can improve your posture with a few simple exercises. Balance-specific workouts address posture and balance problems with exercises that build strength where it counts and stretches that loosen tight muscles. Quick posture checks in the mirror before and during balance exercises can also help you get the most from your regular workout. And increasing your core strength and flexibility can help you improve your posture noticeably in just a few weeks.
Good posture means:
When sitting down, keep your chin parallel to the floor; your shoulders, hips, and knees at even heights; and your knees and feet pointing straight ahead.
