If we have to sit for long periods of time during the day, whether for a job or in the car, the constant pressure of the seat edge against the backs of our thighs can cut off circulation to a certain extent, which can promote trigger points in the hamstring muscles. These trigger points will tighten and shorten the muscles, which in turn can then pull down on the back of the pelvis to which they are attached. The resulting abnormal posture of a posterior tilt and flattening of the lower back curve distorts how the muscles in this area work, often resulting in chronic lower back pain.

If trigger points are already causing mischief within these muscles, then some good deep tissue massages can eliminate them, which followed by regular stretching of your hamstrings, will go a long way to preventing this happening.
