Question

Many people hurt their backs when they try to lift heavy things from the floor. It is easy to hurt your back muscle(肌肉) when you try to pick up a heavy thing. However, there is a correct way to lift things from the floor. If you pick up heavy things correctly, you probably will not hurt your back.

To lift something from the floor correctly, first bend (彎曲) your knees and lower yourself. Keep your back straight. Do not bent over, from your waist (腰) keep your back and hips (臀部) and waist in a line. If you bent over, the muscles in your lower back can became hurt very easily. If you keep your back and hips straight, the muscles are stronger, because they hold up together. The other muscles can then help the lower back muscles.

As you lower yourself, try to get as close to thing as you can, put one knee on each side of the thing. Remember at all times to keep your back straight. Put your hand under the thing that is in front of you, between y our knees.
