For effective lifting, which technique should be avoided?

Lifting with straight arms should be avoided because it puts undue strain on the lower back and increases the risk of injury. When lifting heavy objects, it's important to use the muscles in your legs and maintain a strong, stable posture. Bending your knees while keeping your back straight allows you to engage your leg muscles effectively, providing the strength needed to lift safely.

This technique not only distributes the weight evenly but also minimizes stress on the spine. It’s essential to incorporate your legs into the lifting process rather than relying solely on the arms, which can lead to accidents and long-term musculoskeletal issues.

The other techniques mentioned, such as keeping feet shoulder-width apart, bending at the knees, and maintaining a straight back, are all key principles of proper lifting mechanics that help ensure safety and efficiency during lifting tasks.
