How would you say "strength through discipline" in Quenya or Sindarin?

I've been thinking about a phrase that captures the idea of steady, disciplined effort leading to strength – not just physical, but mental and spiritual too. Something like 'strength through discipline' or 'endurance builds power.'

I know Quenya has words like túrë (strength/power) and móle (effort/labour), but I'm struggling to connect them in a way that feels grammatically correct. In Sindarin, maybe agor (might) or maethor (warrior) could work.

Does anyone have suggestions for existing phrases or help with a translation?

How about this.

In Sindarin: Tass ‘ordh dôl ‘ûr a rhond daug. Difficult work brings a strong mind and body

I believe the Quenya would be: In Quenya: Urda móle tulya turca indo ar hröa.

I am better at Sindarin than Quenya.
