You can sit at a 90-degree right angle when sitting. You can lie with your legs together and bend at a 90-degree angle when you sleep. Sticking to it for a while can improve the width of the fake hip.

The best sitting posture is to separate your legs, shoulder width apart, and put your feet forward on the ground in a straight line with your knees. It must be noted that when doing any movements, try to keep the knees and feet in the same direction. If the joints are not offset, there will be no problem of bad posture.

Don't sit on the coccyx, sit on the ischial tubercle, that is, sit on the chair, try to plug your hips, feel the adduction of the coccyx and abdomen, and keep the pelvis neutral and upright (to prevent the pelvis from leaning forward and the lumbar spine from leaning forward excessively).

Due to the different physiological structures and needs of men and women, the width between pelvis and greater trochanter between them is quite different.

Due to the need of pregnancy, women's pelvis is shorter and wider than men's. The female sacrum is also wider, and the pelvic cavity is wide and round, which is convenient for fetal delivery. Because the female pelvic cavity is wide, the acetabulum (including the articular fossa of femoral head) on both sides is far apart, which increases the distance between the two trochanters, thus widening the hip joint.
