Lift an object by bending your knees and squatting to pick up the object. Keep your back straight and hold the object close to your body. Avoid twisting your body while lifting. Push rather than pull when you must move heavy objects. If you must sit at your desk or at the wheel of a car or truck for long hours, break up the time with stops to stretch. Wear flat shoes or shoes with low heels (1 inch or lower). Exercise regularly. An inactive lifestyle contributes to lower back pain.
