During pregnancy, women often develop back pains from leaning backward while walking. Why do they have to walk this way?
Solution 16DQ During pregnancy, the front side of a woman tends to lean forward because her body mass is more here. But to keep standing straight she has to lean backward to align to her center of gravity which in a normal human being lies along an imaginary vertical line of passing along the body. Thus, back pains may be developed from leaning backward.
