It’s no secret that Carrie Underwood is into fitness. She has her own fitness brand, Calia, and often shares workout videos to her social media. The country star said that even though she loves working out, there is one exercise that she hates. “I hate burpees, I hate burpees so much. My trainer Eve Overland, she loves burpees, and she will do the most insane variations of burpees, and I am just like, ‘No'”.
