A lot of women from the older generation still believe that a pregnant woman should keep her physical activities to as less as possible. This is however, not true for every expecting mother. Mild to moderate activities can be good for you and your baby's health. Yoga is very well suggested for the wellbeing of the child growing inside you. One should carry on with their daily normal routine and also go for regular walks, unless the doctor announces any complications and advises for extra rest. Do take proper advice from your doctor on developing a proper fitness regime during pregnancy.
