When lifting heavy objects, which body posture is advised?

The advised body posture when lifting heavy objects is to keep feet shoulder-width apart and maintain a straight back. This position helps to distribute the weight evenly and provides a stable base of support, reducing the risk of injury. By keeping the back straight, the spine is aligned properly, which minimizes strain on the back and core muscles. This technique engages the leg muscles, which are stronger and better equipped to handle heavy loads, allowing you to lift more safely and effectively.

In contrast, bending at the waist can place significant stress on the lower back, increasing the likelihood of strain or injury. Leaning backward is similarly harmful as it disrupts the center of gravity and can lead to loss of balance or additional strain on the back. Sitting up straight, while it promotes good posture, is not practical for lifting heavy objects, as it does not engage the legs effectively. Therefore, maintaining an appropriate stance with a straight back and feet positioned correctly is essential for safe lifting practices.
