Which of the following is an incorrect practice when lifting?

Using momentum to lift is considered an incorrect practice because it can increase the risk of injury. When lifting heavy or awkward objects, relying on momentum can lead to improper body positioning and strain on muscles and joints. Instead, lifting should be performed with a controlled motion, utilizing proper body mechanics, which emphasizes the use of leg strength rather than back strength. This helps ensure the lifter maintains stability and minimizes the likelihood of accidents or injuries.

Taking breaks during long lifts and engaging your core are actually recommended practices that help in maintaining safety while lifting. Proper body mechanics involve careful planning of the lift and using the body correctly during the process to avoid undue stress. These practices focus on safety and effectiveness, which significantly reduce the potential for injury during physical tasks.
