The 20th century saw multiple trends and changes in women's fitness culture.

The rate of participation of women in the Olympic Games has been increasing since their first participation in 1900. Some sports are uniquely for women, others are contested by both sexes, while some older sports remain for men only. Studies of media coverage of the Olympics consistently show differences in the ways in which women and men are described and the ways in which their performances are discussed. The representation of women on the International Olympic Committee has run well behind the rate of female participation, and it continues to miss its target of a 20% minimum presence of women on their committee.
