Lower back injuries are another form of cumulative trauma disorder.
Most injuries are the result of years of poor posture and improper lifting techniques.
This means that when you bend at the waist to pick up an object, the weight is magnified ten times on the lower back. Since the weight of your upper body is included, bending at the waist to pick up a piece of paper can put over a 1,000-pound stress on your lower back. Therefore, the amount of weight being lifted is not the main problem, it is usually the manner and frequency in which the lift is performed that cause most back injuries. In order to maintain this curve, keep your stomach muscles tight. Stand close to the object and stagger your feet for better balance.
