Arahants and exersise Q:

Would an arahant get physically exausted if he/she was to exersise, like if they were to run 5 miles? Would this in anyway shake their mind?
Buddha's mind is unshakable. But they still get tired and has to rest.

"Ananda, speak to the Kapilavatthu Sakyans about the person who follows the practice for one in training. [2] My backaches. I will rest it."
