Firefighters posted a warning to others after they were called to a hospital to free a man who had trapped his penis in the hole at the centre of a gym weight plate on Friday.
He was reportedly trying to strengthen his penis by using it to lift the 2.5kg disc.
Firefighters spent three hours trying to free him with cutting equipment,The Straits Times reports.
The crew in Worms, Germany, posted a picture of the broken weight on their Facebook page, issuing a warning to men not to try to copy the idiotic move.
“A message of a somewhat different kind was received on Friday morning, 15.09.2017, at the control centre.
“With the help of a cutting grinder, a vibrating saw and a hydraulic rescue device, the dumbbell weight could be removed after three hours.””Please do not imitate such actions!”
