It is mainly due to genetic traits that the body of girls is soft and the body of men is much stiffer. Although the functions of the various organs of the body are the same for men and women, their structural features are slightly different due to hormonal and genetic differences. Differences can also be noticed due to differences in the lifestyle of men and women. Due to the excess of testosterone in the body, the body of men is stronger than that of women. This causes the muscles to swell and the body to become tense. In addition, due to the difference in the fiber in the muscles, the body of men is stronger than that of girls. Although muscle structure is similar to that of males and females, there are more or less fibers due to hereditary traits and physical activity of the offspring. Due to this difference, women's body is soft and men's body is hard. Thanks
