Final answer:
When lifting heavy objects, it's important to lift with your legs, possibly use a hand truck or dolly, and wear a back brace for support, making All of the above the correct option.
Step-by-step explanation:
When lifting heavy objects, the most effective and safe practice is to ensure that you're using your legs rather than your back. This method significantly reduces the amount of force exerted on the spine, making the process safer and less prone to injury. Lifting with a bent back can create abnormally large forces in the back muscles and spine, potentially leading to muscle strain, and damage to discs and vertebrae. Proper lifting technique entails keeping the back erect and bending the knees to raise the body and the load. If a heavy load is too much for manual lifting, using a hand truck or dolly, or wearing a back brace for additional support may be beneficial. Thus, for the question about best practices when lifting heavy objects, the answer would be D) All of the above.
