Hollywood actor Ashton Kutcher seems almost obsessed with keeping fit.
The actor's new motivation for staying in shape is to prepare for Armageddon.
"If the [bleep] hits the fan, you can get out of the [bleep]," the New York Post quoted him as telling Men's Fitness magazine.
Kutcher is currently learning the Israeli fighting technique Krav Maga, which he used for his role in "Killers." He also practices Bikram yoga and jogs up LA's Runyon Canyon to work out.
"All of my physical fitness regimen is completely tailored around the end of day(s). I stay fit for no other reason than to save the people I care about," he said.
