"That man obviously has a big problem... with himself," Underwood wrote.
Oprea was cyber bullied on Facebook recently when a unidentified man shared a photo of her working out at her son’s soccer game.
“Would it be wrong of me to tell her that every dad at the soccer filed thinks her standing out front with her jump rope for two hours only screams she wants attention. And I can only imagine what the soccer moms are thinking,” the post read along with a picture of the former Marine’s back.
Well, unfortunately for him, Oprea and Underwood, 32, got the last laugh. Both ladies shared a screenshot of the post on social media, and had a few words for him.
“Way to go, Erin! Use someone else’s negativity to help others. That man obviously has a big problem… with himself,” the country singer captioned her photo.
“I only hope he can learn to like himself someday so he can be an adult and stop bullying others for bettering themselves!” she wrote adding, “This guy felt the need to post this pic of my friend and trainer, Erin Oprea, along with some really insecure and mean comments. He was shaming her for getting in some exercise during her son’s soccer game. Not cool.”
Meanwhile, Oprea also shared a lengthy post on her website.
“This is exactly why many people don’t embrace an active lifestyle in ordinary situations: They are worried that they will draw attention and, even worse, ridicule,” she posted. “I don’t want to see people getting bullied for doing what works best for their lifestyle. What I do care about are those who would love to be out moving but worry that they re being judged.”
And Oprea concluded by writing words of encouragement for all fitness fanatics.
“So grab your jump rope, embrace that healthy lifestyle and keep on jumping if you hear whispering behind you. You’re the better person here in more ways than one,” she said.
