CARRIE UNDERWOOD's legs are becoming as famous as her voice. CMT talked to her trainer, a woman named Erin Oprea, and she said people come to her because they want Carrie's legs.
She doesn't give them false hope. She says it comes from "hard work, determination, and discipline." And you can't be afraid of pumping iron, either . . . because, quote, "Weights make pretty muscles."
Erin has also worked with Kelsea Ballerini, Maren Morris, and Kacey Musgraves.
