How do you ensure proper body mechanics while lifting?

The correct approach to ensure proper body mechanics while lifting is to bend at the knees, keep the back straight, and hold objects close to the body. This method emphasizes the importance of using the body's larger muscle groups in the legs instead of straining the smaller, more vulnerable back muscles. By bending at the knees, you lower your center of gravity, providing greater stability and balance. Keeping the back straight minimizes the risk of injury by preventing undue stress on the spine. Additionally, holding objects close to the body reduces the leverage and strain on the back, as the weight is more directly supported by the legs and core.

In contrast, twisting the back to get a better grip can lead to injury as it places significant stress on the spinal discs and muscles. Lifting only with the arms can result in back strain because it does not utilize the strength of the legs, which is critical when lifting heavier loads. Allowing the back to bend while using only the legs for lifting increases the risk of injury due to poor posture and mechanics during the lifting process. Following the correct method not only safeguards personal health but also promotes a safe working environment.
