Women with low-risk pregnancies can exercise safely throughout their pregnancies. In fact, moderate physical activity is considered to be beneficial for most pregnant women and their babies. Despite the benefits of physical activity, it is important to check with your health care provider before you begin. Pregnant women should always be able to speak comfortably while exercising. Any exercise with potential for abdominal trauma should be avoided.
Pregnant women are more prone to injury of the ligaments.
Jumping or bouncing types of exercise should be avoided or performed carefully. After 20 weeks, pregnant women should avoid exercise while lying flat on the back. This can restrict blood flow to the fetus.
