If your struggling with low back pain, you will instinctively want to rub your lumbar area or try and stretch out your entire back. Sometimes though, lower back issues can be caused by tight hamstrings, the muscles on the back of your upper leg. Desk workers for example, sit for great lengths of time so the hamstrings are restricted (shortened) for long periods of time as well. Every now and then, while you are seated, stretch one leg out in front of you, point your foot in the direction of the ceiling, and with a straight back, slowly bend forward and feel the stretch up the back of your leg. You can improve the stretch by placing a tennis ball or rolled up hand towel under your hamstring as well. Make sure you do both legs. With all of your best efforts, sometimes you still need a pair of remedial hands to ease out those tight muscles so that you can get the full effect of your stretching.
