Flattening The 'Mummy Tummy' With 1 Exercise, 10 Minutes A Day

A few weeks, later I'm rolling out a yoga mat with a dozen other moms and pregnant women in San Francisco.

"We will see a dramatic change," says, who leads the class. "You can easily expect to see 2 inches off your waist in three weeks of time," Keller says. "That's not an unrealistic expectation."
