What is the recommended angle for lifting to minimize strain?

The recommended angle for lifting to minimize strain is 45 degrees from the body. This angle strikes a balance between maintaining mechanical advantage and ensuring that the load is close enough to the body for effective lifting. When lifting at a 45-degree angle, the body can engage large muscle groups, such as the legs and hips, rather than relying heavily on smaller muscles in the back and arms. This helps to reduce the risk of injury and strain to the back, which is crucial in healthcare settings where professionals frequently lift or move patients and equipment.

Lifting at angles significantly deviating from 45 degrees can either increase the distance from the body, potentially leading to increased strain on the muscles, or put the lifter in a position that does not leverage their body's strength effectively, resulting in higher risk of injury.
