What is “GOOD” Posture?
Good posture is not just standing or sitting up straight. Forcing the body into a rigid, upright position simply tightens the leg and back muscles and may lead to other musculoskeletal problems.

A complex system of spinal and pelvic muscles are working constantly (24/7! Even in sleeping) to maintain our upright posture, our balance and stability, as well as our health and well being. These group of muscles, often referred to as our “core” muscles, are constantly providing torso position and stability for us to be able to use our limbs and function without injury.
In “good” posture, the head, neck, shoulders, pelvis, hips and knees are in alignment and the spine has 3 normal curves that counteract the effects of gravity on our upright posture. If there is weakness in the groups of postural muscles, gravity effects the bony alignment of the skeleton and postural misalignment develops. Pain, discomfort and poor function develop uniformly throughout the body.
The spine is made up of a number of vertebrae ranging in body size from small (neck) to large (lower back and pelvis). Small muscles called “inter-vertebral muscles” make our upright trunk posture possible. Longer vertebral column muscles provide some stability for the spine as well as movement of the trunk (including the neck and pelvis) in backwards or side bend movements. The smaller vertebral muscles provide stability for the spine segmentally and are very important in maintaining optimal function in all daily activities. If there is weakness in these muscle groups the result is “poor” posture, bony misalignment and muscular imbalance as a result of the effects of gravity pulling the body downward. After an illness or injury, it is the postural muscles that are challenged first and should be rehabilitated before any other activities are attempted.
TRANVERSE ABDOMINALS AND PELVIC FLOOR MUSCLES.
The “INNER CORE” Muscles.
The diagram to the right illustrates our pelvic girdle muscles. These are another group of very important postural muscles. When these muscles are strong and functioning at an optimal level, they provide intra abdominal support for our internal organs and stability for our lower back. They act as a “corset” for the lower abdominal and pelvic region and help prevent low back injury, prolapse of internal organs and incontinence.
EFFECTS OF “POOR “POSTURE ON THE MUSCLES, SPINE AND GENERAL HEALTH.
A “slouched” posture, aside from looking bad, can have very negative effects on your entire body. Carrying the head in a forward position, puts immense strain on neck and shoulder muscles and can cause mid and lower back pain. Headaches, joint and muscle aches and pains may increase. Shoulders hunched forward result in a “pot belly” signifying weakening of the abdominal and pelvic floor muscles. The pelvis may shift out of alignment shortening the hamstring muscles and place more stress on the lower back. The musculoskeletal system and the nervous system are unable to work efficiently and health problems develop.
HEALTH PROBLEMS ASSOCIATED WITH “POOR” POSTURE.
Headaches, Jaw Pain, Neck Pain and Strain, Neural Tension, Vertebral Disc Degeneration, Sleep Problems, Poor Balance, Shoulder blade Dysfunction, Tightness in Chest and Diaphragm, Breathing Difficulties, Reduced Range of Movement in Shoulder Joints, Nerve Impingements, Pain and Discomfort in Ribs, Problems with Digestion, Constipation or Bowel or Bladder Incontinence, Poor Balance, Lethargy and Tiredness, Muscle Weakness or Fatigue, Tight Hamstrings, Hips and Hips Flexors, Difficulty Walking or Rising from a Seated Position, Short, Shuffling Gait, Reduced Spinal Flexibility, Difficulty Bending or Twisting, Problems Standing, Sitting or Walking for long distances or periods of time.
The list can be endless, these are just a few of many musculoskeletal and biomechanical problems associated with poor posture over a long period of time.
CORRECTIVE EXERCISE.
As we can now see, good posture is a combination of muscle groups working in synchronicity to provide stability for the spine, support for the internal organs, and maintain balance and a stable upright posture. Good posture is not only important in standing, but also in sitting, lying down, walking and in all the everyday activities we participate in. A corrective exercise program that addresses postural dysfunction should include a variety of movement patterns designed to recruit the postural muscles in an organized sequence as well as in isolation. A proper exercise program should be designed within the parameters of a person’s gender, age, body type and posture and fitness level. It should always address the environmental demands on that person’s body (i.e.; work stations, work demands, lifestyle, sport and recreation) and any pre existing conditions or injuries.
Walking tall or attempting to stand or sit up straight is not enough to address these postural muscles. Choose exercises that challenge these deep core muscles and avoid using exercise or gym equipment that does not recruit large muscle groups in compound movements. Stretching tight neck, shoulder and chest muscles regularly is also recommended.
