With a doughnut, the jam can be squeezed around depending on where you put the pressure on the bun. If you squeeze it too hard, then the jam will likely escape.
It is just the same with the disc. When you bend forwards or sit down, the pressure is placed on the front part of the disc. This has the effect of squeezing the disc core (shown in red in the picture) backwards. The more bending forward or sitting you do, the more you are encouraging the disc material to move in a backward direction.
If you decide to lift something with your back bent, then you are adding a tremendous force to your disc. Basically you are asking for trouble!
