The U.S. Occupational Safety and Health Administration offers diagrams of proper lifting techniques on its website. These diagrams display the correct posture for lifting and the ideal power zone to minimize strain on the spine and small muscles of the back.
Industrial supplier Grainger also provides a series of pictures showing the correct technique for each step of the lifting process. Each picture includes a written description with safety tips to help customers reduce lifting injuries in the workplace. Oklahoma State University offers a back safety guide with visual examples of proper technique and tips to reconfigure work spaces so less lifting is necessary.
