Exercise in pregnancy boosts strength, endurance and flexibility, while at the same time strengthens the muscles, which will help you during pregnancy and will prepare you for the physical ordeal of childbirth.
What kind of exercise can choose a pregnant?
This depends on the physical condition of each woman. If you don’t exercise at all you will have to choose, always in a consultation with the doctor of a mild exercise, such as walking or swimming. If the woman is more active and athletic type or already done some sports, you most likely can continue, as long as to adapt it to the needs of pregnancy.
In general it is good to avoid the sports with which you come in contact with others (such as martial arts), as well as there is a risk of falling from a height, such as horse riding and climbing. From water sports, those that are prohibited include skiing and scuba diving. Avoid scuba diving, as it is not known if the increase in pressure will affect pregnancy or your baby. In any case, before you do anything, just to come in consultation with your doctor.
