 This will be a randomized controlled trial of primiparous women with singleton pregnancies who plan on delivering at Prentice Womens Hospital. Women will be recruited during their first trimester by their obstetrician as well as through standardized Northwestern Memorial Hospital flyers and ads. Demographic and delivery information will be obtained from the Northwestern Enterprise Data Warehouse EDW, as well as by the attending midwife or physician at the time of delivery using a standardized Delivery Information Form. Women will also be asked about their other physical activities including other forms of dailyweekly exercise as well as whether or not they are participating in other birthing classes at the time of their first Total Control class intervention group or 2nd trimester visit with their providers controls. All women will wear pedometers to track daily general activity.
