Jo Lindner, a YouTube training star known as Joesthetics, died Friday of an aneurysm. He was 30 and his death was confirmed by friends. The German fitness influencer had 8.5 million Instagram followers, and his videos had almost 500 million views on his YouTube channel. Lindner’s last post on social media talked about his fitness levels after taking a year off of intensive bodybuilding. Earlier in June, in an interview for an episode of fellow YouTuber Bradley Martyn’s Raw Talk, he revealed he had a condition known as rippling muscle disease. That causes muscles to be overly sensitive to movement or pressure. “Technically, it’s a cramp,” he told Martyn.
