If you wish to lift a heavy box, the main safety precaution is to squat down close to the box, rather than bending over to reach it, and then lift it by using your legs, rather than your back. The human back muscles are quite strong, but the spine can be injured by over exertion, and chronic back ache is a very common problem that people develop. Other than that, boxes are easier to lift if you tie them up with strong twine or cord, which you can then hold onto. If the box is seriously heavy it might even take two people to lift it. It is probably a good idea to make sure that you know in advance where you are going to put the box once you have lifted it; this is not something that you will want to have to figure out while you are holding a heavy box. Try not to work in cluttered conditions. You do not want to trip over something while holding a heavy box. Remember that the box alters your balance and also hides part of the floor from your view. And if the box is really too heavy for you, it may be possible to simply unpack it, and pack the contents into two or more smaller boxes.

The tension rope pulley can be used to efficiently lift heavy objects by distributing the weight of the object across multiple pulleys, reducing the amount of force needed to lift it. This allows for a mechanical advantage, making it easier to lift heavy objects with less effort.

Ants are able to lift heavy objects many times their own body weight due to their small size and the proportionate strength of their muscles. Their bodies are designed with specialized muscles that allow them to exert a great amount of force relative to their size, enabling them to carry objects that may seem too heavy for them. Additionally, ants often work together in groups to lift and transport heavy objects, utilizing teamwork to accomplish tasks that would be impossible for an individual ant alone.

When lifting heavy objects, you should bend your knees and keep your back straight to use your leg muscles instead of your back. Hold the object close to your body and lift with your legs rather than your back to avoid injury. Make sure to ask for help if the object is too heavy to lift on your own.

A lever is used to lift heavy objects because it magnifies the input force applied to it. By using a lever, a person can apply a smaller force over a longer distance to lift a heavier load over a shorter distance. This principle allows for the efficient lifting of heavy objects with less effort.
