Which guideline is recommended for exercise during pregnancy?

The recommendation to stop exercising if the woman feels tired is grounded in ensuring the health and safety of both the mother and the developing fetus. During pregnancy, it is normal for a woman's body to experience increased fatigue due to hormonal changes, physical changes, and the additional energy required to support the growing baby. Listening to one's body and recognizing when to stop exercising is crucial as it helps prevent overexertion and reduces the risk of complications.

Maintaining physical activity within comfortable limits allows pregnant women to benefit from exercise, such as improved mood, reduced discomfort, and better overall fitness, without pushing their bodies beyond what feels manageable. Therefore, prioritizing rest when fatigue occurs is essential for a healthy pregnancy experience.

In contrast, other recommendations like increasing intensity over time or engaging in exercises that involve bouncing and arching the back are not advised during pregnancy due to the potential risks they pose to stability and safety. Exercising in a warm environment can also be detrimental, as overheating can negatively affect fetal development. Thus, the correct guideline emphasizes listening to one's body and prioritizing well-being during exercise in pregnancy.
