Which part of the body should you use for lifting to prevent injury?

• A. Shoulders
• B. Back
• C. Legs
• D. Arms

Answer: (C)

The main idea is using your legs to lift because they’re built for generating power and carrying loads. When you bend at the knees and hips and keep the spine in a neutral position, you drop your body to the weight and then straighten the legs to lift. This lever action places the force through the large leg muscles—quadriceps, hamstrings, and glutes—while keeping the load close to your center of gravity. Keeping the weight close reduces the lever arm and the stress on the spine, so you’re less likely to injure your back.

Lifting with the back or with the arms tends to place excessive stress on the spine and shoulder/arm muscles, especially if you twist or lean forward. The back isn’t designed to repetitively bear heavy loads, and bending at the waist can compress spinal discs. If the load is too heavy to lift safely, seek help or use lifting equipment.

So, using the legs is the best approach because it leverages your strongest muscle groups and minimizes spinal strain.
