What kind of exercise is specifically not recommended during pregnancy?

Rock climbing is specifically not recommended during pregnancy due to the inherent risks associated with the activity. This type of exercise involves climbing steep and sometimes unstable surfaces, which can lead to falls or injuries. Additionally, the need for balance and core strength in rock climbing may be compromised as a woman's body changes throughout pregnancy, increasing the risk of accidents.

In contrast, swimming, walking, and yoga are generally considered safe and beneficial forms of exercise during pregnancy. Swimming can provide a low-impact workout while being gentle on the joints, walking is a natural form of exercise that can be easily adjusted to a comfortable level, and yoga offers flexibility and relaxation, promoting overall well-being. These alternatives can help support health without the elevated risk factors associated with more extreme sports like rock climbing.
