A disgraced bodybuilder has been slammed after he shared a video of himself laughing at an elderly woman attempting to use gym equipment.

Conor Tisdell uploaded the clip on Wednesday, with the well-articulated caption “Epic bro gainz”, later saying she must be “practicing her new dance move” in the comments below.

Another victim of Tisdell’s anti-social behaviour said she noticed he was laughing at her when she was attempting to do a squat under the guidance of her personal trainer.

“It's disgusting, he's starting an ongoing trend to publicly shame and embarrass people,” the woman, identified only as Deb, told the Daily Mail.

"The most disgusting part is this gym is in a very low socio-economic part of Brisbane... I can handle it, but when I saw what he did to this elderly woman, I was shocked."

Meanwhile, a health club staff member reportedly endorsed Tisdell's anti-social behaviour on Instagram.

“Aw when you know who the member is," the female employee said jokingly on the Instagram post.

While some of Tisdell’s social media followers appeared amused by his efforts, others pointed out that he should have helped her out rather than publicly shame her.

"What a vile person, inside and out," one Facebook user wrote.
