Have you ever tried yoga or tai chi? I read recently that these type of exercises help achieve physical and mental balance that can be helpful in correcting and preventing low back pain.
According to WebMD:
The series of yoga poses called asanas work by safely stretching your muscles. This releases the lactic acid that builds up with muscle use and causes stiffness, tension, pain, and fatigue. In addition, yoga increases the range of motion in joints. It may also increase lubrication in the joints. The outcome is a sense of ease and fluidity throughout your body.
Yoga stretches not only your muscles but all of the soft tissues of your body. That includes ligaments, tendons, and the fascia sheath that surrounds your muscles. And no matter your level of yoga, you most likely will see benefits in a very short period of time. In one study, participants had up to 35% improvement in flexibility after only eight weeks of yoga. The greatest gains were in shoulder and trunk flexibility. cite:http://www.webmd.com/balance/the-health-benefits-of-yoga?page=2
Kind of scary though that WebMD's first paragraph warns against injury. Perhaps you should contact a physical therapist about back pain first. Click here to read about how physical therapy might help.
