For the love of wverything... Arm wrestling... Arm in pain.... "There's nothing to endure here"..... REALLY? I feel that entire competition He should have had the option of using endure the entire time
Endure requires concentration, I believe. It's hard enough to keep these women from slamming your hand down on the table.
Either way, Endure would just take away the pain, not the effort required. And pain produces adrenaline, which serves as a boon in this case.
