Which of the following is NOT an example of an awkward posture?

The chosen answer highlights squatting to lift an object as the correct response, indicating that it is not considered an awkward posture. Squatting is generally recognized as a natural and biomechanically advantageous position for lifting. It allows individuals to leverage their leg muscles, which are typically stronger than those in the back, thereby minimizing the strain on the spine. By bending at the knees and keeping the load close to the body, an individual can maintain better balance and protect against injury.

In contrast, other options reflect postures that can lead to discomfort or strain. Bending over to tie shoes typically involves a forward flexion that can place stress on the lower back. Working with elbows above shoulders can strain the shoulders and upper back, increasing the risk of musculoskeletal disorders, especially with prolonged exposure. Twisting while reaching for a box can compromise spinal alignment and lead to injury through excessive rotational forces.

Thus, squatting is the posture that aligns with ergonomic principles, making it the correct answer to the question.
