What is a key component of proper body mechanics to prevent injury when lifting?

• A. Use a wide stance, bend at the knees, keep the load close, and use leg muscles; avoid twisting while lifting.
• B. Lift with the back and twist during lifting.
• C. Keep the load far from your body.
• D. Exert maximum effort with one arm.

Answer: (A)

Proper body mechanics when lifting means letting the legs do the work, keeping the load close to your body, and avoiding twisting. Stand with a stable base, bend at the knees and hips rather than the back, and lift with the leg muscles while the weight stays near your midline. Keeping the load close reduces the lever arm on the spine, so less stress is placed on the back, and maintaining a neutral spine with no twisting minimizes torsional and shear forces that can cause injury. The goal is to transfer the effort from the back to the legs and keep the load aligned with your center of gravity. Lifting with the back and twisting, keeping the load far away, or using one arm would increase spinal stress, create imbalanced loading, or add torque, all of which raise the risk of injury.
