What practice helps keep the weight of the dolly in your power zone?

• A. Pushing the dolly rather than pulling it
• B. Pulling the dolly
• C. Lifting the dolly overhead
• D. Carrying the dolly in front of you

Answer: (A)

Keeping the weight in your power zone means keeping the load close to your center of gravity and at a height where your strongest muscles can do the work. Pushing the dolly lets you use your legs and hips, maintaining a neutral spine, instead of pulling with your arms and back. When you push, you can apply force from your lower body, keep the load near your torso, and avoid reaching or twisting that would push the weight outside your power zone. Position the dolly at about waist height, stand with feet shoulder-width apart, and push forward rather than pull. Lifting overhead or carrying the dolly in front or pulling it would force you to reach, twist, or strain your back, making it harder to keep the weight in your power zone. So pushing the dolly is the best practice for staying within your power zone.
