The Drop a Jeans Size Workout

"Your muscles are made up of thousands of fibers," says trainer Brad Schoenfeld, author of the soon-to-be-released Women's Home Workout Bible, who developed the program exclusively for FITNESS. "A regular squat might call into play 70 percent of the fibers in your derriere, then a side lunge might tone 10 percent more. Do the 10 moves in this sculpting routine and you'll work 100 percent of those fibers."
Part 1: Toning

Do two sets of these toning exercises twice a week — take a day off in between workouts.
What You'll Need: A set of 3- to 8-pound dumbbells and a stability ball (or a bench)
Part 2: Cardio

Do our simple, trimming cardio sessions (found in the last few slides of this workout) three times a week to downsize your denim in 28 days.
