In what way should lifting objects be performed?

Lifting objects correctly is crucial to prevent injury and ensure safety. Bending at the knees and using leg strength is the recommended approach because it engages large muscle groups in the legs, which are designed to handle heavier loads. This method helps to distribute the weight evenly across the body and reduces the strain on the back.

By bending at the knees, the lifter lowers their center of gravity, which enhances stability during the lift. Utilizing the legs for the lifting motion rather than the back helps to avoid twisting or over-exerting the spine, minimizing the risk of injuries such as sprains or strains.

In contrast, twisting the back, using only the arms, or keeping the feet together can compromise balance and increase the likelihood of accidents or injuries. Therefore, the correct technique emphasizes the importance of proper body mechanics in lifting heavy objects safely.
