When lifting heavy objects, which part of the body should bear the bulk of the physical effort?

When lifting heavy objects, the legs should bear the bulk of the physical effort. This is because the legs are the strongest muscles in the body and are designed to support and lift heavy weights efficiently. Proper lifting techniques advocate bending at the knees and keeping your back straight to avoid injury. Engaging the legs allows for better leverage and minimizes the risk of strain on the back, which is more susceptible to injury if it takes on the lifting burden.

Using the arms or hands primarily can lead to improper lifting posture and increased risk of injuries, especially to the back. Maintaining a strong stance with the legs not only distributes the weight more effectively but also helps in maintaining balance and control while lifting. Remembering to use legs rather than relying solely on arms or back is crucial for safe lifting practices.
