What is "Ich mag nümm"

This is me on my workout sessions where I keep saying "Ich mag nümm"

I think I need to change my attitude.

In our next Monday VIP lesson we have 4 short dialouges about working out.

​E Gruppe vo junge Fraue träniert dusse:
A group of young women exercises outside.

Du schaffsch das.
You can do it.

Das isch so schwirig. Ich schaffe das nid.
No, this is so difficult. I can’t do it.

Du muesch dehei meh üebe.
You must practice more at home.

Ich mag nümm.
I can’t do it anymore.

Hör uuf z jammere!
Stop complaining!
​
Dänk dra, ohni Fliis, kei Priis.
Remember, no pain no gain.
