Back pain problem. Why is it so?

Hi..., You husband may be able to avoid back pain or prevent its recurrence by improving your physical condition and learning and practicing proper body mechanics. Exercise. Regular low-impact aerobic activities — those that don't strain or jolt your back — can increase strength and endurance in your back and allow your muscles to function better... Maintain a healthy weight. Being overweight strains back muscles. If you're overweight, trimming down can prevent back pain. Use proper body mechanics: Stand smart. Maintain a neutral pelvic position. If you must stand for long periods, place one foot on a low footstool to take some of the load off your lower back. Alternate feet. Good posture can reduce the stress on back muscles.
