Kitasan Black is stuck in a losing streak. While talking to Nice Nature, she gets the idea to attempt a more intensive training regimen, since she's not prone to injury. Trainer isn't convinced that's such a good idea...
And it looks to me like the exhaustion 
is taking a toll on her motivation.
ويبدو لي أنّ الإنهاك يؤثر على حافزها
Ihre Kraft und damit ihre Motivation
sind im freien Fall.
Está exhausta y cada vez la veo
menos motivada.
Está exhausta y cada vez la veo
menos motivada.
Avec la fatigue,
je sens une baisse de moral.
E mi sembra che la stanchezza 
stia mettendo a dura prova la sua motivazione.
E parece que a exaustão está
afetando a sua motivação.
И мне кажется, что усталость 
влияет на её мотивацию.
