During pregnancy, women can exercise in appropriate activities, such as yoga and walking, but not strenuous exercise such as fitness. When women are pregnant, they can exercise moderately, such as walking, swimming, yoga and other ways to promote blood circulation and control excessive weight gain, which is beneficial to the development of the fetus, and generally does not cause uterine contractions and fetal development. However, excessive exercise, such as fitness, strenuous running, etc., is not allowed, and these may cause uterine contractions, resulting in miscarriage and preterm delivery of the fetus. During pregnancy, pregnant women should develop adequate health care awareness to promote their own health as well as that of the fetus. If discomfort occurs after exercise, care should be taken to seek prompt medical attention.
