Carrie Underwood leaps to defence of personal trainer

Country star Carrie Underwood has publicly slammed a man she accused of bullying her personal trainer on social media.

A spectator at a soccer game, in which Erin Oprea's son was a player, posted a photo of the celebrity fitness guru exercising on the sidelines on Facebook.com and suggested she was seeking male attention.

"Would it be wrong of me to tell her that every dad at the soccer filed (sic) thinks her standing out front with her jump rope for two hours only screams she wants attention," the man wrote. "And I can only imagine what the soccer moms are thinking."

The Cowboy Casanova singer leaped to her personal trainer friend's defence, sharing a screenshot of the critic's comments on Instagram.com and adding the caption "Way to go, Erin! Use someone else's negativity to help others. That man obviously has a big problem... with himself."

"I only hope he can learn to like himself someday so he can be an adult and stop bullying others for bettering themselves!

"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."

Erin, a former Marine, also hit back at the unnamed critic on her website, stating such judgmental comments put many women off the idea of exercising in public.

"This is exactly why many people don't embrace an active lifestyle in ordinary situations," she wrote. "They are worried that they will draw attention and, even worse, ridicule.

"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."
