Pain in the lower back can keep golfers in bed and off the course. The deep stabilizing muscles of the lower back, called the multifidi muscles, can be strengthened to prevent and relieve lower back pain. A physical therapist may be consulted to properly diagnosis pain that is consistent. There are several exercises you can do at home to work the multifidi muscles. Depending on your therapist's advice, develop a daily, or at least regular, lower back exercise regimen.
