Pelvic Tilts

Pelvic tilts are an exercise comprised of very subtle movements that strengthen the support muscles around the low back, particularly the abdominals. They are a good preliminary exercise for those seeking low back pain relief, and they feel great because they give your back a little massage. They can be done lying on the floor or standing with the back to a wall. The standing version is a bit more difficult, but it is a good option for pregnant women who are not comfortable on their backs.
