What is a key factor in maintaining balance while lifting?

Maintaining balance while lifting is crucial for both safety and effectiveness. The practice of keeping one's feet apart at shoulder-width is fundamental because it creates a stable base of support. When the feet are positioned shoulder-width apart, the center of gravity is better aligned directly over the feet, significantly enhancing balance during the lifting process. This stance allows for the distribution of weight evenly, reduces the risk of tipping or falling, and provides greater power and control when lifting heavier objects.

In contrast, having feet set together would typically reduce stability and increase the likelihood of losing balance. Extending arms while lifting can compromise posture and increase the strain on the back, making it harder to maintain equilibrium. Relying on only one leg for support would lead to an unstable position and increase the risk of injury, as it does not allow for adequate weight distribution necessary for safe lifting. Thus, the choice of keeping feet apart at shoulder-width is the most effective strategy for ensuring balance and safety during lifting activities.
