"Fortitude" comes from the Latin word "fortis," meaning "strong," and in English it has always been used primarily to describe strength of mind. For a time, the word was also used to mean "physical strength" -- Shakespeare used that sense in The First Part of King Henry the Sixth:

"Coward of France! How much he wrongs his fame
Despairing of his own arm's fortitude."

But despite use by the Bard, that second sense languished and is now considered obsolete.
