FAIRBANKS, Alaska (June 21, 2012)—Firefighters came to the rescue after an Alaska man decided to climb a tree for exercise but ended up stuck upside down, dangling by one leg.

Fairbanks firefighters had to use a ladder truck to reach the 53-year-old man, who was dangling nearly 30 feet off the ground.

He was uninjured.

Assistant Fire Chief Ernie Misewicz told The Fairbanks Daily News-Miner the man decided to climb the tree because "it was something he wanted to do."

He said the man had spikes and a belt around his stomach, but said he lost his grip and fell backward.

The belt slipped below his waist, flipping him over.

Authorities were alerted by a friend, whom the man called from a cell phone attached to a lanyard around his neck.
