The hamstrings, a group of three muscles located in the back of the thigh, can contribute to lower back pain. So keeping the hamstrings properly stretched and limber is a good formula for relief of lower back pain or sciatica pain, which tends to run down one side of a leg. A regular routine of hamstring stretching eases tightness that generates stress on the low back. The hamstrings run from the pelvis down to the knee.
Here are some tips to help you avoid low back strain: 1  If you feel any low back pain during physical activity, stop. 2  If you feel low back pain within a day of stepping up your workout, take it easy for a few days. 3  Get your back in shape. Exercise and stretch your back muscles regularly.  Avoid sleeping on your stomach.
