According to safe lifting practices, what is recommended regarding load height?

Performing lifts at waist height is recommended because it minimizes the strain on the back and helps maintain proper body mechanics. Lifting at waist height allows the body to engage the core muscles effectively while reducing the risk of injury associated with bending or reaching. This position is ergonomically favorable as it helps to keep the load close to the body, where it can be managed more safely.

In contrast, lifting from the ground can place considerable strain on the lower back and require more effort, particularly if the load is heavy or bulky. Lifting overhead generally increases the risk of injury and is not advisable as a standard practice for safety—it's best reserved for specific strength training scenarios under controlled conditions. Additionally, lifting without considering height disregards essential ergonomic principles, potentially leading to poor body mechanics and increased risk of injury.
