A South African bodybuilding champion fatally injured himself while attempting a backflip (video below).
Sifiso Lungelo Thabete broke his neck while performing his signature move on Aug. 5 during a competition, reports News 24.
He was rushed to the hospital, where he passed away from his injuries.
"We suspect, because he was wearing socks this time, that he slipped or didn't get enough momentum and landed horribly on his head," BodyBuilding South Africa National Executive President Wayne Price explained.
As a former International Federation of Bodybuilding and Fitness Junior World Champion, Thabete had a promising future ahead of him, reports Daily Mail.
Thabete's fatal backflip was captured on video and shocked many.
"What a truly awful thing to happen to a young man who has clearly devoted so much time and energy into being the best he can be at his chosen career," wrote one Daily Mail reader. "Very sad. So pointless."
"Doesn't matter how many times you do something successfully, it only takes the one time you don't," said a second. "Such a tragic loss waste of a young life."
Upon watching the clip, some also argued people should be discouraged from performing such moves.
"I'm glad it was shown," wrote another individual. "I'll replay it to my 15 year old son and his dopey friends who have spent hours doing backflips for fun. All it takes is one mistake. Poor man and his family."
"So sad," added another. "Young people need to be discouraged from these back-flips unless properly trained. I saw a video on YouTube where the same thing happened to a footballer celebrating a goal. I can never watch these type of videos ever since as it's too sad."
"Thrillseekers need to weigh the risk versus reward," a third chimed in. "Terrible consequences here. RIP Sifiso."
"One minute he is alive and extremely well and the next minute he is dead," said a fourth viewer. "You just never know the moment your time is up. Be nice to everyone people."
Yet others criticized people for watching and sharing the video, calling it insensitive.
"Why are you showing video of him dying," wrote one person. "Out of respect for his family please take it down."
Thabete's family, it appears, agrees with that sentiment.
"We're aware of a video of the incident circulating on social media, as is Sifiso's family, and they're understandably very upset about that," said the police.
