Common areas of complaint for pregnant women are sciatic pain in the low back, buttocks, and thighs. Exercise to reduce the tension are prenatal yoga postures that focus on “lengthening” the muscles in the backs of the legs. A great example is modified pyramid pose
To do the move:
Pyramid pose: Step your right foot forward about 3-4 feet in front of the left leg. Place your hands on each side of your right foot. You may use blocks to reduce the tension on the back of your leg. Bend your upper body forward over your right thigh. Inhale and exhale through your nose. Focus on lengthening the back of your leg. Repeat the breath 8-10 times then switch sides. Notice the difference in how you feel. Do you feel less tension? Do you feel you stand taller?
