Women should be encouraged to become fit before they become pregnant. During pregnancy, those who were accustomed to aerobic exercise before pregnancy can probably continue their sports involvement throughout pregnancy, at the same perceived level of exertion. Weight training and calisthenics are advisable during pregnancy, even for those who never practised them before. Pregnant women should avoid high intensity, prolonged duration, hyperthermia, dehydration, abdominal trauma, and low oxygen availability in exercise.
鼓励女性在怀孕前保持健康。在怀孕期间，那些在怀孕前习惯有氧运动的人可能可以在整个怀孕期间以相同的感知运动强度继续参与运动。即使是那些从未进行过举重和体操训练的孕妇，在怀孕期间也建议进行举重和体操训练。孕妇在运动时应避免高强度、长时间、体温过高、脱水、腹部创伤和低氧供应。
