Jack Osbourne is so thrilled with his newfound fitness, he's preparing to climb a 3,593-foot (1,095 metre) monolith.

The 19-year-old son of rocker Ozzy Osbourne, who has lost more than 14 kilograms (30 pounds) in the last four months, successfully scaled a mountain in the south of France on 8 July (05).

And now he's set his sights on climbing Yosemite National Park's El Capitan.

He says, "I feel bulletproof. You have to be in top condition to do El Cap."
