PRENATAL Prenatal yoga addresses those muscular–skeletal changes that accompany pregnancy. For instance, low back strain is very common as is pain generated from impingement of the sciatic nerve and there are postures and movements that help relieve and/or prevent these conditions. With a committed practice, the pregnant woman is better prepared for the challenges of labour and delivery. The practice itself is gentle yet challenging, incorporating traditional postures, breath awareness exercises and relaxation strategies. These are small, semi-private classes.
