A video showing an MMA coach repeatedly hitting his fighter has been widely condemned by the industry as abusive

• A disturbing video that shows an MMA coach hitting his fighter is being rebuked by the industry.
• Diego Sanchez hangs upside down, shirtless, while coach Joshua Fabia punches, slaps, and kicks him.
• Jon Jones said he's "disgusted," Conor McGregor said it's madness, and Alex Morono called it creepy.

A video that appeared to show MMA coach Joshua Fabia repeatedly hitting his fighter Diego Sanchez is being roundly rebuked by the industry as abusive and inappropriate.

The video, which has since been deleted, shows Sanchez - a UFC hall of famer - hanging upside down while shirtless.

Fabia, also shirtless, continually strikes Sanchez with punches, open-palm strikes, and even kicks him at one point in the clip.

After attempting to absorb the blows without a guard, Sanchez covers up to try to block the incoming shots.

The video ends after less than a minute with Sanchez swinging around like a pendulum because he's getting hit so much. It is unclear how long the training session lasted.

SB Nation website MMA Mania reports that the video is not new, but shows the "odd" teaching methods Fabia uses.

Prominent UFC fighters are 'disgusted'

The former UFC light heavyweight champion Jon Jones, regarded by Insider as one of the best fighters in all MMA, said in a since-deleted tweet that he's "without words, really disgusted."

According to MMA Fighting, Jones said: "As a person that knows Diego, this is the last thing he needs."

Jones was not the only prominent fighter to be appalled by Fabia.

MMA Mania reported that Conor McGregor said in a tweet that he has since deleted: "This is just madness."

The former two-weight UFC champion added: "Working the body … doing it hanging upside down, and getting the dome of the head struck repeatedly, while covering vision, is preposterous!

"Grab this guy by the ears and head butt him at his front door first thing."

He finished by remarking: "This is not his story Diego. Box his nose in and ditch him."

Fresh from his first-round knockout win over Donald Cerrone at a UFC Fight Night event Saturday in Las Vegas, Alex Morono shared his thoughts with the reporters present at the post-fight press conference.

"I've built such a resume for myself as a martial artist for two reasons: one, for my own personal goal accomplishing reasons and two: so my students know that their coach has gone through the fire.

"For as long as there's been society, people have been fighting. Martial arts have been around forever. And so long as martial arts has been around, there have been these fake coaches," Morono said.

"Just who, they believe their stuff is real, and I can't believe how embedded this one is in Diego. I'm sure you've seen the video of [Diego] hanging upside down getting punched and kicked in the head. That is insane … crazy to see."

Morono said that any child who wants to learn martial arts has to have a parent or guardian who does research on every coach that will be alone with their students.

"If you don't know, message me and I'll do the research and let you know," he said. "It makes me so mad when creepy adults lead their students astray."
