What is a critical consideration when lifting heavy objects?

Bending the knees is critical when lifting heavy objects because this technique helps to distribute the weight more evenly across the body and utilizes the strong muscles in the legs rather than relying solely on the back and arms. By squatting down and keeping the load close to the body, you significantly reduce the risk of injury, particularly to the spine. Proper lifting mechanics are essential in preventing strains and ensuring stability, especially with heavier loads.

Using the legs to lift instead of the back minimizes the potential for overexertion and provides better leverage, making the operation safer. Bending the knees ensures that individuals are engaging their core and leg muscles, which are designed to bear weight more effectively than the back.
