Manual lifting of loads

Typically, many people suffer from back problems, which are visible as they age and almost always result from poor use of the laws of physics.

I agree that the correct position is not natural – it is an uncomfortable position – and it takes a lot of training to use it automatically, unconsciously.

To understand the importance of correct and incorrect position we can think of a spring.

In the incorrect position, we place greater effort on the spring, tilting it, forcing the spring coils to the limit - wearing out and even breaking vertebrae.

If we use the correct position the greatest effort is in vertical, compressing the coils – this is extremely favourable for the stability of the spring's flexibility and, by analogy, for the structure of the spine.

When we use the incorrect position we use the spine structure as a lever with the fulcrum at the base of the column – without much exaggeration it’s possible that a weight of 30kgf is leveraged to hundreds of Kgf.

I have vertebral disc protrusion (L5) and sometimes I have sciatica attacks – it is extremely painful and disabling. Despite this, when the crises disappear (taking medication), many times I forget the correct position and return to the incorrect position.
