When properly lifting a heavy object, what physical posture should you maintain?

Keep your knees locked
Bend your back forward
Keep your back straight while bending your knees
Use your hips for leverage

The correct answer is: Keep your back straight while bending your knees

Maintaining a proper posture while lifting a heavy object is crucial to avoid injury, particularly to the back. Keeping your back straight while bending your knees allows you to utilize the strength of your legs, which are more capable of handling heavy loads compared to the back muscles. This approach distributes the weight more evenly and reduces the strain on your spine. When you keep your back straight, it helps maintain the natural curvature of the spine, which is designed to bear weight and allow for movement without excessive strain. Bending your knees allows you to lower your center of gravity, increasing stability and making the lift safer and more efficient. This method supports the body's biomechanics, reducing the risk of spraining or straining muscles and ligaments in the back. Proper lifting techniques are essential for both safety and efficiency when handling heavy items in various settings, from construction sites to office environments.
