The use of correct body mechanics is intended to do what?

• A. Use the strongest muscles
• B. Increase speed
• C. Improve flexibility
• D. Reduce the need for rest

Answer: (A)

Using correct body mechanics means performing tasks in a way that protects your body by coordinating posture, balance, and the power from the body's strongest muscle groups. When you lift, transfer, or move a heavy load, engaging the legs, hips, and core rather than relying on the back helps you generate the force you need from the body’s most capable muscles. Keeping the load close to your center of gravity, bending the knees, and maintaining a neutral spine all shift the work to these strong muscles, which reduces strain on the back and lowers the risk of injury. In health care settings, this approach is about safety and efficiency during daily tasks, not about moving faster, increasing flexibility, or needing less rest.
