Ronda Rousey’s Mom, Dr. Ann Maria DeMars, on her daughter’s quick work of Sarah Kaufman

“If it’s not broke, don’t fix it.”

That’s the philosophy of Ronda Rousey‘s mother, Dr. Ann Maria Rousey DeMars, on her daughter’s continuing stoppage of opponents in the first round via armbar submission.

Dr. DeMars became the first American to win the World Judo Championships in 1984, and began teaching her daughter armbars and other grappling techniques at a very early age. And now, several years later, her daughter is the Strikeforce women’s 135-pound champion and the leading women’s mixed martial arts fighter in the world.

Following Ronda’s 54-second defeat of Sarah Kaufman Saturday night, Dr. DeMars talked with ( reporter Daniel Theodore about her daughter’s enormous success, the nerves she experiences watching her daughter fight and her thoughts on Ronda doing the ESPN Body Issue.
