Champion climber Magnus Midtbø, 27, posted the image on Instagram after going climbing at the popular tourist attraction on the weekend.
“Treating my legs with a much needed break after a long hike to Trolltungen,” he wrote.
“Glad we decided to make a stop on the way south. Definitely worth the six hour hike! The question remains; can it be climbed?”
Kjersti Eidsnes from the local police district complained on the weekend that the stunt risked encouraging others without Midtbø's skills to risk their lives.
“ My first thought is that when these kinds of images spread, some people will get the ideas of trying to outdo each other with similar energetic stunts,” she told state broadcaster NRK.
Norwegian local rescue services are being called out more and more often to Trolltunga as tourists clamber to take pictures on the promontory without preparing properly for the long climb up to the spot.
In September last year an Australian tourist fell to her death from the rock while she was posing for a photograph, one of dozens of accidents requiring the emergency services to be called out.
The rock, which juts out 700m above Ringedalsvatnet, a lake three hours West of Bergen, is one of Norway's most popular attractions.
Midtbø has been Nordic climbing champion seven times, and is a former junior world champion in sport climbing.
