Hugh Jackman exhausted with workout regime

London: Hollywood star Hugh Jackman has got a muscular look with his tough fitness regime but he found the whole process exhausting.

The 44-year-old `Prisoners` star, who has been following a diet created by David Zinczenko, said that his diet has left him with low energy, reported Daily Telegraph.

"I`m just off the 8-Hour Diet from Dave Zinczenko of Men`s Fitness. Water dehydration got me that ripped look. I`m so low energy I`m literally sleeping all the time because I`m on a zero-carbs, limited-calories diet," Jackman said.

The actor, who is married to Deborra-Lee Furness, cannot stay still in his sleep.

"I`m the busiest sleeper on the planet. My wife says about every 15 seconds I kick, run, turn around, like I`m running a marathon. If you`re on a plane next to me, you wonder what`s going on with that guy," he added.
