What are safe methods of lifting heavy objects?

1. Bend at the waist and lift

2. Lift with your arms

3. Bend your knees with your back straight

4. Twist your torso while lifting

The correct answer is: Bend your knees with your back straight

When lifting heavy objects, bending your knees while keeping your back straight is recognized as a safe method because it helps to maintain a proper posture. This technique engages the stronger muscles in your legs to do the lifting instead of straining your back. By maintaining a straight back and bending at the knees, you reduce the risk of injury, such as strains or sprains that can occur when using improper lifting techniques. This lifting method promotes a stable center of gravity and allows for better control of the load, which is crucial for preventing accidents. The engagement of leg muscles also allows you to lift heavier items more efficiently since the legs are stronger and can better support the weight. Other methods, like bending at the waist, are risky as they place undue stress on the spine, while lifting with just the arms can lead to overexertion, particularly if the legs are not used to assist in the lift. Twisting your torso while lifting can cause a sudden and unsafe shift in weight, further increasing the likelihood of injury. Therefore, adopting the technique of bending your knees while keeping your back straight is essential for safe lifting practices.
