There are many benefits from doing so.
Examples are shorter labor time and the lowering of pregnancy discomforts.
Always consult a doctor before beginning any exercise routine. Come up slowly, one vertebrae at a time, uncurling into a standing position.

It concentrates on strengthening the abdominal muscles as well as the lower back.
