The well-known instructor on the 'Joesthetics' network has died suddenly at the age of 30.
The deceased had earlier complained of a mysterious pain in the neck which was later revealed to be an aneurysm from blocking blood arteries. There are no other official explanations for the causes of his death.
The German influencer known for his YouTube videos, whose real name was Jo Lindner, became famous for giving his followers training tips, personal life stories, diet and lifestyle.
His girlfriend announced today on the Instagram network that unfortunately the 30-year-old had passed away.
Sharing images and videos of the pair, Jo's girlfriend Nicha, also a fitness instructor and online influencer, told followers he was now "in a better place".
She wrote: "He passed away yesterday from an aneurysm ..I was in the room with him ..he put a pendant he had made for me around my neck, and then he was in my arms when it all happened so fast."

"Three days ago he was telling me he had a pain in his neck ... we didn't understand anything, ... until it was too late."
Nicha said she couldn't write more about fans asking her for an explanation for the sudden death, but would only say that Jo was 'so much more' than they knew.
"He was loving, honest and trusted everyone."
Numerous tributes were made on the network by the trainer's fans. His fellow bodybuilder Noel Deyzel said: "Rest in peace Jo." We will miss you.”
