Fitness trainer Travis Burdine won't call himself a hero, but the woman he SAVED, sure will.
"I was on this treadmill, just minding my own business," says 49-year-old Kim Steele.
Steele is a member of the gym where Burdine works, in the town of Prague.
She says her her blood pressure, her weight, her cholesterol, have always been fine.
So nobody was more surprised than she was, when a 95-percent blockage in her artery dropped her in her tracks with a massive heart attack.
"There was a guy here working, and I heard him scream that he needed help," Burdine said.
He said Steele was on the floor next to the treadmill, out cold, turning purple.
Burdine started doing CPR until paramedics arrived.
"The doctors said that if it had been a minute longer, I would have been dead," Steele said.
Steele has since made a full recovery.
Burdine was named the Oklahoma Heart Hospital's Heart Hero of 2014.
They hope everyone will learn CPR.
