What lifting technique would put Ted at risk for injury?

Lifting with his back puts Ted at risk for injury because this technique can lead to strain on the muscles and ligaments of the lower back. When someone lifts with their back, they typically bend at the waist, which increases the likelihood of improper lifting posture and can lead to serious injuries such as muscle strain or disk herniation. In contrast, the safer lifting techniques—like using a teammate for assistance, utilizing hand trucks, or bending the knees when lifting—are designed to distribute the weight more evenly and reduce stress on the spine. By maintaining a proper posture and engaging the larger muscles of the legs instead of relying solely on the back, Ted can minimize his risk of injury while lifting heavy objects.
