Final answer:
It is true that incorrect lifting form can cause muscular and/or joint injury, as it can lead to muscle strain and damage to spinal discs and vertebrae due to increased force on the back muscles and spine.
Step-by-step explanation:
True, incorrect lifting form can indeed cause muscular and/or joint injury. When lifting objects, particularly heavy ones, it is crucial to employ proper technique to distribute the load evenly and reduce strain on any one part of the body, especially the back. Lifting with your legs and keeping your back straight helps maintain proper alignment, while using your back to lift can lead to increased force on the muscles and spine, potentially causing muscle strain, and damaging discs and vertebrae. This is because the back muscles and spine are not designed to handle heavy loads in a bent position, thus leading to a significant risk of injury.
