The classical standard of exercising for lower back
problems is the so-called Williams Flexion Exercises. Developed by Dr. Paul
Williams around 1950, this series of exercises strengthens the buttocks and
abdominal muscles and stretches not only the muscles of the lower back, but the
hamstring muscles as well.
Another popular and successful set of exercises are
the McKenzie Extension Exercises. They attempt to reduce disc pressure by
moving the lumbar spine backward in extension. None of the various exercise
options has been clearly shown to be more advantageous than another.
Therapists commonly recommend combining both the Williams Flexion and McKenzie
Extension exercises to stabilize the spine and strengthen tight muscles.
General physical conditioning, aerobic exercising (increasing the breathing and
heart rate), and flexibility exercises are helpful in the long run for
preventing recurrences of low back pain.
