In addition, when your body is in this position, the muscles of your lower back are forced to lift the weight of your torso along with the weight of whatever you happen to pick up. Place your hands on either side of the object, if it is large, and position it close to your body. Lift the object and your body by using your leg muscles. If you have an injury that prevents you from bending at both knees, try kneeling on one leg and lifting from this position. Your abdominal muscles act in opposition to your back muscles.
Strong abdominals support the lower back.
Sleep on a firm mattress and sleep on your side. Sleeping on your stomach increases pressure on your back. During a long car ride, place a rolled up towel at the small of your back for extra support. Maintain good body posture when sitting or standing. Slouching increases pressure on the back.
