What is a recommended practice when lifting heavy objects?

Using a firm footing with feet wider than shoulder width is crucial when lifting heavy objects because it provides a stable base of support, helping to balance the load and reduce the risk of falling or straining yourself. A wider stance allows the legs to bear more weight and engage larger muscle groups, like the quadriceps and gluteus muscles, which are better equipped for lifting compared to the back alone. This method not only enhances safety but also increases lifting efficiency by utilizing the strength of the lower body, thereby minimizing strain on the back.

The other practices are less safe: using your back to lift can lead to serious injuries such as strains or herniated discs; lifting quickly can compromise form and increase the risk of injury; and using only one hand could cause imbalance and increase the chances of dropping the object or injuring oneself.
