WORLD:

How far are we - generally speaking - in terms of mobility in everyday life below our capabilities?

Marcel Gaudlitz:

Unfortunately, we never use our joints more fully in everyday life.

Because when do we move our knee into complete flexion?

When do we go fully into extension of the elbow joint?

In everyday life we ​​only use around 20 to 30 percent of the range of motion that we can theoretically make possible in a joint.

Usually not the rest.

WORLD:

And then the joints rust, as the saying goes?

Gaudlitz:

You can imagine it vividly like a sponge: if a sponge for the blackboard at school used to not be used for a long time or was not soaked in water for a long time, then it became rock hard.
