Of the following, the best way to stand when lifting a heavy object from the ground is with the feet:

When lifting a heavy object from the ground, the most effective and safest stance involves placing the feet a little apart, pointed the same way, with the knees bent and the back held upright. This posture helps distribute the weight evenly and allows for better stability and balance while lifting.

Bending the knees is crucial because it utilizes the strength of the legs rather than straining the back. An upright back maintains proper alignment, reducing the risk of injury. By standing with a slight separation between the feet, the body has a stable base to work from, preventing the likelihood of losing balance during the lift.

This method aligns with ergonomic principles that promote safe lifting techniques, emphasizing the use of large muscle groups while maintaining a posture that minimizes stress on the spine. It contrasts with the other options, which either compromise stability or place undue stress on the knees and back by not incorporating proper bending or alignment.
