Your neuro-muscular-skeletal system is delicately balanced and interconnected. When a muscle is too weak or even too strong, it places abnormal stress on another muscle. The muscle that is stressed will compensate for a while, but eventually it will begin to hurt.
Strengthening the abdominal muscles can help prevent lower back pain. One of the chief causes of lower back pain is weak abdominal muscles. The abdominal muscles hold the lower torso and if they are weak, the back muscles will be forced into strainful positions and efforts.
Posture plays a vital role in maintaining a healthy back. Stand straight, with your stomach muscles firm and your buttocks tucked in. Don’t way your back or let a curve develop in the lumbar region. Also, try not to sink into one hip or the other. Good posture will not only save your back, it will also make you look much more attractive and fit.
Sitting is more stressful to the back than standing, so if you have a sedentary job, get up and move around often. Make sure you have a chair that has adjustable height, so you can sit with your feet flat on the floor and your knees slightly higher than your hips. Your chair should be firm, but not totally hard, with armrests and tilt-and-swivel mechanisms.
Rest on a good firm mattress, and never sleep on your stomach. Lying on our side with the hips and knees slightly flexed is the best position; lying face up is also okay.
Correct ways to move your body and back: “before lifting contract your stomach muscles”; “lift with your legs, not with your back”; “squat down and pick it up and stand up, as opposed to bending at the waist”; “don’t lift and twist at the same time”; “know your limits and get help when you’re lifting something that you know is too heavy”.
