Which posture is incorrect among the given options for pushing and pulling guidelines?

• A. Torso, Hands, Shoulders
• B. Feet
• C. Arms, Shoulders, Hands
• D. Torso, Arms, Hands, Shoulders

Answer: (D)

The main idea is that safe pushing and pulling should be powered by the legs and hips, with a stable base, while the spine stays neutral. When you use the legs, you keep the load close to your center of gravity and protect your back from strain. The posture that lists the torso, arms, hands, and shoulders without including the feet/legs is not appropriate. Relying on the upper body alone shifts the effort to the back and shoulders and can cause twisting or overloading the spine. A proper approach uses a solid stance with feet apart for balance, bends the knees, engages the legs to push or pull, keeps the load close to the body, and brings the elbows in to keep the arms and shoulders in a safe, aligned position.
