Question

body mechanics: when lifting something off the ground, which body part should you always use? your back your abdomen. your arms your legs

Explanation:

When lifting, using legs (with knees bent) helps maintain proper posture, reduces strain on the back (which is vulnerable to injury if misused), and utilizes the stronger leg muscles for the task. The abdomen and arms alone are not sufficient for safe and effective lifting from the ground compared to the legs.

Answer:

Your legs.
