Both men and women can exercise during pregnancy preparation. Proper exercise is good for the body. For both men and women, being physically active not only strengthens the body and provides healthy sperm and eggs for future conception, but also relieves the stress of pregnancy preparation to a certain extent, so that the mind and body can be healthier to welcome a new baby. For women in particular, moderate exercise during pregnancy preparation can have an impact on the success of conception and the health of the fetus by maintaining a proper weight. Exercise can also improve a woman’s cardiorespiratory capacity. Pregnancy requires a certain level of cardiorespiratory capacity, and women with better cardiorespiratory capacity will feel more relaxed throughout the process from conception to delivery; on the other hand, poor cardiorespiratory capacity is a risk factor for both the pregnant woman and the fetus. Although it is recommended that men and women exercise during pregnancy preparation, it is also important to pay attention to the appropriate amount of exercise and not to overdo it and cause injuries. The specific exercise program and the length of exercise can be planned according to your situation.
