Chad Michael Murray almost died when he was 15 because his abs were too tight.
The One Tree Hill star has recalled how doctors struggled to find out what was happening to him because of his toned physique, as his stomach "didn't expand" when he started bleeding.
Chad was suffering from twisted intestines and his parents even had a priest in the room because it was fatal.
Appearing on SiriusXM, the Freaky Friday star said: "They didn't know what was wrong. This sounds so stupid — and trust me, I'm not on an ego trip when I say this — but because I was in physical good condition, my abdomen was tight and when I started bleeding internally, my stomach didn't expand.
"Basically, my abs kept it flat so the doctors couldn't tell I was bleeding. They saw my red and white blood cells dropping but they didn't know where it was going.
