What technique should you use when lifting or setting down a load?

Using the technique of bending at the knees when lifting or setting down a load is essential for ensuring safety and preventing injury. This method engages the body's strong leg muscles rather than putting undue stress on the back, which is more vulnerable to injury when lifting heavy objects.

When you bend at your knees, you're able to lower your center of gravity, which provides better balance and stability while you lift. This technique allows you to maintain a more upright posture, keeping your back straight and reducing the risk of strains or other back-related injuries. It promotes proper lifting mechanics by allowing the larger muscle groups in your legs to perform the majority of the work, rather than relying on your back.

In contrast, bending at the waist can place excessive strain on the lower back. Lifting quickly is not advisable as it can lead to improper form and increase the chances of injury. While keeping your back straight is important, it is best achieved in conjunction with bending at the knees for an effective and safe lifting posture. Thus, bending at the knees is recognized as the correct technique for safely lifting or setting down a load.
