A recent study examined the positive effects of regular physical activity during pregnancy. A combined lifestyle intervention including dietary counseling and twice-weekly exercise classes during pregnancy resulted in a slightly longer first stage of labour without any other effects during labour or delivery report researchers.

The Norwegian Fit for Delivery study included 303 pregnant women who participated in dietary counseling and twice-weekly exercise classes
