Bodybuilding star Jeff Nippard was attacked by another fitness guru this week while recording a workout session at a gym in Canada… and the attack was caught on video!

Nippard – known for his scientific approach to bodybuilding – broke his silence on the incident after a video emerged showing Nippard being violently pushed to the ground Mike Van Wyck at the Pure Muscle and Fitness gym in Ontario.

“Mike Van Wyck shoved me in the throat twice in the middle of the gym and then pushed my cameraman,” Nippard said on social media Monday.

“There’s already a lie going around that Mike asked me to stay away from him and that I didn’t listen and reach out to him first. This is WRONG.”

Nippard went on to explain that Van Wyck apparently had a problem with JN filming for his popular YouTube channel.

“He then walked back towards me, said ‘turn off the camera’ and immediately punched me in the throat, causing me to fall to the ground,” Nippard said.

“I got back up and he told me never to talk about him again. Then he pushed me in the throat a second time.”

Jeff also says Van Wyck attacked his cameraman before walking away.

Nippard said he wasn’t sure why Van Wyck reacted the way he did … but suspects it stemmed from a video he made in response to WMD in which he calls science-based fitness influencers “mediocre.”

“In my opinion, it was the result of the anger generated by the clip I posted yesterday in response to his question about science-based education,” Nippard said. “Pretty wild stuff.”

The 34-year-old says he went to the hospital for a CT scan after the attack… before telling more than 2 million IG followers that he was fine.

Fellow bodybuilders have rallied to Nippard’s defense…including Quinton Eriyawho said he would no longer train with Van Wyck because he didn’t deal with bullies.

Fitness star and nutrition coach Joel Twinem also spoke out and said the incident was not staged.
