Drop 2 inches in 4 weeks

“This workout is so effective because it’s about quality, not quantity,” Bethenny says. Each move targets not only the abs but other muscles, too, adds trainer Kristin McGee, who helped create this regimen (and joins Bethenny on her Body by Bethenny DVD): “With Bethenny’s hectic schedule, it pays to have an ab workout she can do anywhere.”

To drop up to 2 inches in just 4 weeks, McGee says, do these moves 3 times per week, plus 20-minute high-intensity intervals 3 times per week and 45 minutes of moderate intensity cardio 2 times per week.
