What is the correct technique for safe lifting?

The technique of bending at the knees and using leg strength is essential for safe lifting because it utilizes the body's strongest muscles while minimizing the risk of injury. When lifting heavy objects, the legs are considerably stronger than the back, and by bending at the knees, you maintain a lower center of gravity which enhances stability. This approach helps distribute the weight of the load more effectively across the body and reduces strain on the lower back.

In contrast, pulling a load while bending at the waist can torque the spine and increase the risk of back injuries. Keeping the load far from the body can also lead to unnecessary strain, as it requires greater effort from the back and arms rather than allowing the legs to do most of the work. Lifting with straight arms places additional strain on the shoulders and back, which can lead to overexertion and injury. Hence, the proper technique emphasizes bending at the knees, utilizing leg strength, and keeping the load close to the body for a safer lifting experience.
