Are endurance and perseverance the same thing?

No — one is physical, the other is mental. Endurance is your capacity to continue an activity for a long time. Perseverance is the mindset that keeps you committed even when it’s boring, uncomfortable, or slow to show results. Endurance gets you through a long workout; perseverance gets you out the door on days you don’t feel like training.

They work together, but they describe different strengths.
