Safe Lifting Techniques, Safe Back!! We lift things several times daily, from a toothbrush in the morning to plates, bags, small children, big heavy boxes, and furniture, Lifting is such an integral part of everything we do that we tend to do it automatically, without thinking. And that’s when it can become a problem – suddenly we’ve lifted something and our back starts to hurt. Lifting things incorrectly can cause a variety of injuries to our back and other parts of our body. Back strain, caused by overstretching certain muscles, is the most common type of injury. Lifting incorrectly can also cause a hernia. These types of injuries can be worse if we’re not in good physical condition. Poor posture, lack of exercise, and stress, coupled with incorrect lifting, can be a hazardous combination.
