Which of the following represents a safety guideline during lifting?

Engaging your legs when lifting is a fundamental safety guideline that helps protect your back and bodily structure. The legs are the strongest muscles in your body and are designed to handle heavy weights. By bending your knees and using your leg muscles to lift, you minimize the strain on your back, which is more vulnerable and prone to injury if it’s the primary muscle used during lifting.

Incorporating leg strength into your lifting technique also promotes balance and stability, making it easier to control the weight being lifted. This practice reduces the risk of accidents or muscle injuries that can result from improper lifting techniques. It's a key principle taught in ergonomic training to encourage safe practices in environments where manual lifting is common.
