Usually, we do this on the same leg, out of habit. Two-thirds of our body weight is now stretching the ligaments on one side of the pelvis. This causes spinal distortion and postural misalignment. Eventually these ligaments may become as severely distorted as from a serious, sudden injury to the back. Standing for extended periods.
Most people find it tiring to remain standing for any length of time.
When this happens, the muscles which hold us erect soon tire and we slump into poor posture positions. Now our entire weight is pulling against ligaments, especially those in the pelvis and lower back. The years take their toll on these ligaments. They become stretched and weakened so that they cannot properly control our joints with the tight support we must have. Discomfort and even pain will then be experienced just from the strain of standing erect.
