Answer A: Bend at the Knees and Use Your Leg Muscles
The safest way to lift heavy objects, including children, is to keep your back straight, bend at the knees and tighten your abdominal muscles when lifting and putting down. Carry the weight close to your body and be sure to avoid twisting, and don’t try to lift objects (or children) that are too heavy for you. Women frequently injure their backs while doing household chores (lifting a vacuum cleaner up stairs, scrubbing floors) or taking care of children. In addition, frequently reaching for objects above shoulder height or bending or twisting while picking up objects -- even light ones -- from the floor can boost your risk of back pain.
