This terrible personal trainer tried to fat-shame a woman into hiring him, and it totally backfired

Self-acceptance can be one of the hardest traits for anyone to learn, and in todays competitive, image-obsessed world, it can feel as though its never been more difficult to master.

And when there are people in that world like this personal trainer, who tried to fat-shame one woman into receiving his exercise expertise, the road to a healthy state of mind can feel mighty long.

The man, who accosted Cassie Young, a digital director for The Bert Show, on Twitter, had no motive for reaching out to Young other than money.

His exchange with Young is maddening, as he tries to badger her into feeling unhappy about her appearance and her body simply so that she'll pay him for his services. Unfortunately for him, Young deftly parried his attacks, and shared the experience in a Facebook post that has since gone viral.

Perhaps the worst part of the entire conversation is that the man used Young's engagement announcement as cause to bother her with his bogus fitness philosophy.

"I know you want to look your best on wedding day," he told her. "If you don't hire me, hire someone. Those pictures last centuries."

"Health is one thing, and it's something I'm working hardcore on," she replied back. "But the idea of being embarrassed by my wedding pictures because I might be 'fat' in them and people centuries from now will be ridiculing me? That's the insinuation and I say F—k that noise!"

Nevertheless, his uninvited criticism persisted.

"You can accept how you look but you can't be happy with the way you look," he told her. "You can't lie to yourself."

Their conversation continued on in this manner until Young effectively shut him down altogether.

"I reject your notion of operating on superficiality and looks, and I embrace my inner health goals," she said. "It's F—KING MEAN TO MAKE SOMEONE FEEL BAD ABOUT THEMSELVES BASED ON THEIR APPEARANCE. It's a s—tty thing to do, and even s—ttier to try to convince someone otherwise so you can profit off it. Get some morals."

Amen to that.

"You are worthy," she reminded her followers in the Facebook post detailing the incident. "Love is out there for you. Life is waiting with open arms. It doesn’t matter if you’re skinny or fat or between the two or willowy or broad shouldered or peer shaped or like a board or anything in between. You get good stuff in life by being YOU. That's what matters."

Even though learning to love your body can feel like the toughest task, Young's story shows that doing so will make you stronger than ever. Need some help supercharging your own swagger? Follow these three steps to exude more confidence today.
