Flat Stomach

Cardio Each tummy type has a customized prescription that spells out how long and how often to work out. You get to choose the type of activity (walking, jogging, cycling, swimming, Spinning, or step aerobics). The goal: burning fat to reveal your firmer abs.

Total-Body Strength-TrainingEveryone does at least two sessions per week for head-to-toe toning and boosting metabolism. In a Korean study, women who combined cardio and strength-training lost almost three times as much belly fat as those who did only cardio. For a sample workout, go to www.prevention.com/tummytype.

Core Moves All types do the belly-firming Core Moves twice a week. For faster toning, add an extra session.
