Firefighters in a German city said it took about three hours to free a man who had “a very sensitive part of the body” stuck in the center hole of a dumbbell weight.

The Feuerwehr Worms Fire Department said in a Facebook post that firefighters responded Friday to a hospital in the appropriately named city of Worms after a man at a local gym ended up with a dumbbell disc stuck around his penis.

The firefighters said it took them about three hours to break through the 2.5-kg weight using tools including a grinder and a hydraulic saw.

“With the help of the grinder, a vibration saw… the dumbbell weight could be removed after three hours,” the fire department posted, including a photo of the dumbbell weight broken into five pieces.

“Please do not imitate such actions!” the Facebook post added.
