Jack Osbourne has come a long way since his days as the portly, rebellious son of Ozzy Osbourne on MTV's The Osbournes. The younger Osbourne has given up the drugs and alcohol that drove him to rehab as a teenager. He also cut out cigarettes and junk food, and adopted a very active lifestyle. A fitness regime that reflects his passion for extreme sports, including rock climbing and kickboxing, has helped Osbourne lose 70 pounds and counting. As the star a new reality show, Adrenaline Junkies, which airs in the UK, Jack Osbourne shows off his fitness fortitude and tackles lofty goals. Osbourne rose above the challenge when he climbed to the top of El Capitan, a 3,000-ft. granite wall in Yosemite. (Getty Images)
