The ideal, healthy posture, is one with a straight line through ears, shoulders, hips, knees and feet. The body stands naturally straight, neither leaning forward or back.
This is an OK posture. Standing straight the abdomen protrudes slightly indicating possible expansion in the stomach or liver.
A forward leaning posture with a slightly protruding abdomen and shoulders pulled in indicates a weakening of the digestive system.
The posture of the upper body is ok but the hips protrude too much indicating possible problems with the reproductive / sex organs.
A tired, listless posture with a protruding chin, retracted shoulders and extended lower abdomen. Difficulty holding the neck straight. Reminiscent of elderly frailty and general fatigue.
A rounded back with abdomen thrust forward and leaning indicating stomach and kidney problems.
This overweight posture suggests constipation, bloating and flatulence with likely lower back pain problems.
