Which body parts should primarily do the work when lifting?

When lifting, the primary body parts that should do the work are the legs and arms. Proper lifting technique emphasizes the importance of using the legs because they are much stronger and more capable of handling the weight than the back. When you bend your knees and engage your leg muscles, you can maintain a more stable and balanced posture. This technique not only allows for a more efficient lift but also significantly reduces the risk of injury to the back, which is more susceptible to strain.

Arms are also important in the lifting process as they help with grasping and maneuvering the object being lifted. By using both legs and arms effectively, you distribute the load more evenly and utilize your body's strength to its fullest potential. This approach aligns with ergonomic principles aimed at promoting safety and efficiency in various lifting tasks, especially in a hospital or clinical setting where heavy and awkward lifting can be common.

In contrast, relying solely on the back or only on one set of muscles can lead to improper form and increase the likelihood of injury. Thus, engaging both the legs and arms provides a balanced and safer lifting technique.
