Jo Lindner, better known as the bodybuilding influencer "Joesthetics," has died. He was 30.
The German fitness guru had built an impressive Instagram following of 8.4 million by posting often about his gym workouts and training regimen.
His girlfriend, Nicha, known as @immapeaches online, shared a bittersweet tribute to the late bodybuilder Saturday on Instagram, reporting an aneurysm caused his death.
She claimed he had complained of neck pain just days earlier.
She called Lindner sweet, kind, loyal, strong and a "believer in everyone."
"Rest in peace Jo. I love you man," fellow fitness fanatic Noel Deyzel wrote on Instagram, along with a photo of the pair together.
"I still keep checking my phone waiting for your reply so we can meet at the gym," he wrote in a longer message. "I'm broken bro. You opened your arms up to us, you showed us so much about life and social media."
He added, in part: "Your generosity towards myself and others will always stay with me."
Lindner's close friend Joseph Shulkin wrote, per The Sun, that the bodybuilder had inspired him and millions.
"You have done so much for the community, had the best energy, and the kindest soul," he said. "We will always remember you brazza, fly high."
Lindner's last post on social media detailed his latest fitness endeavors after taking a year off of intensive bodybuilding.
"When I lost my gains because I went off everything for 1 year but then could not recover my own test levels so went back on trt," he wrote, in part, referring to his testosterone replacement therapy.
"Trust me I tried to stop but be aware it might have long term effects for your life," he continued. "Trt is a big commitment keep that in mind."
