Which action helps minimize the lever effect when lifting a load?

• A. Keeping the arms and weight close to you
• B. Extending the arms away from the body
• C. Bending at the wrists only
• D. Pushing with the chest

Answer: (A)

Minimizing the lever effect when lifting means keeping the load close to your body so the distance from your spine to the load is short. The longer that distance, the greater the torque your back muscles must generate to keep you upright. By pulling the load in and keeping your arms near your torso, you shorten that lever arm, making it easier for your legs and core to lift and reducing strain on the back. This also helps you stay balanced because your center of gravity stays closer to your body. Extending the arms away increases the lever arm and the torque your back would have to counter, which raises the risk of injury. Merely bending at the wrists doesn’t address the lever distance or engage the legs, and pushing with the chest isn’t an effective lifting technique for reducing lever effects.
