At 6'3" and 195 pounds, Ashton Kutcher is ready to take on the world with his strength.

Demi Moore's 32-year-old hubby, who is the cover boy for January's issue of Men's Health, tells the mag:

    "All of my physical fitness regimen is completely tailored around the End of Days. I stay fit for no other reason than to save the people I care about.”

Ashton also reveals that he does hours of Bikram yoga, trains in Krav Maga and regularly runs Runyon Canyon in LA. As for modern conveniences, the actor says we have too many.

    “People don’t have maps anymore. People use their iPhones or GPS systems, so if there’s no electricity, nobody has maps. And people are going to go, ‘That land’s not yours, prove that it’s yours,’ and the only thing you have to prove it’s yours is on an electric file. Then it’s like, ‘What’s the value of currency, and whose food is whose?’ People’s alarm systems at their homes will no longer work. Neither will our heating, our garbage disposals, hot-water heaters that run on gas but depend on electricity."

Easy tiger! But at least Ashton will be prepared no matter what comes his way. He says, "What happens when all our modern conveniences fail? I’m going to be ready to take myself and my family to a safe place where they don’t have to worry.”

Lucky Demi!
