Which exercise is generally advised against during pregnancy due to increased risks?

Cycling is often advised against during pregnancy due to the increased risk of falls and injuries associated with balance and stability issues that can arise as the pregnancy progresses. While stationary cycling might be considered safer, traditional outdoor cycling poses challenges such as road hazards, loss of control, or sudden stops that could lead to accidents. This is particularly pertinent as pregnancy alters a woman's center of gravity, which can affect balance.

In contrast, running, swimming, and yoga are typically viewed as safer options for pregnant individuals. Running can usually be maintained if the woman was already accustomed to it pre-pregnancy; many women continue to run with appropriate modifications throughout pregnancy. Swimming is particularly beneficial because it provides a low-impact way to stay active and is less likely to result in injury. Yoga can enhance flexibility and improve mental well-being and is often adapted to be safe for pregnant individuals, focusing on relaxation and breathing techniques.

The decision to modify or avoid activities like cycling during pregnancy is based on ensuring the safety and health of both the mother and the developing fetus.
