Questions & Answers about Min ryg bliver stiv, når jeg sidder længe.
Because ryg is a common gender noun in Danish, so it takes min in the singular.
- en ryg = a back
- min ryg = my back
If the noun were neuter, you would use mit instead:
- et ben = a leg
- mit ben = my leg
So the possessive has to match the grammatical gender of the noun.

- Jeg bliver træt = I get tired
- Det bliver koldt = It gets cold
