Fit into Your Skinny Jeans in 4 Weeks

Target Your Butt, Belly, and Thighs

Tired of the exasperating zipper dance you perform each time you don your favorite pair of jeans? Well, get ready to zip up with ease: We've got the perfect plan to firm your butt, flatten your belly, tone your thighs, and blast fat everywhere.

"To instigate real body changes, you must shake up your typical routine," says Tracey Mallett, owner of the ATP Specific Training & Physical Therapy Center in South Pasadena, California. One of Mallett's top transformational strategies is to use a flight of stairs for both cardio and strength workouts. "Stair climbing instantly boosts your heart rate, builds endurance, and provides an added muscular challenge," says Mallett.

Do the following strength and stair workouts three times a week on nonconsecutive days. Add one hilly hike or longer run on weekends to blast even more calories and you'll be slipping into those skinny jeans in one month!

The Best Jeans for Your Body

If you have a muscular or curvy lower body...

Do: Choose a darker wash to minimize your build; find jeans with some Lycra in them for a more comfortable fit.
Don't: Be afraid to show your shape. Avoid baggy silhouettes, which can make you look heavier than you are.

If you have saddlebags or a pear shape...

Do: Choose shades darker near outer and inner thighs to slenderize them; wear a boot cut to elongate the legs.
Don't: Wear jeans that are too stretchy; they'll hug in the wrong places.

If you have a narrow build or flat butt...

Do: Get pockets that are on an angle to give the illusion of shape; wear low-rise cuts to show off your waistline.
Don't: Go too baggy.

If you have belly pooch...

Do: Choose a mid-rise or classic fit to camouflage your middle.
Don't: Go too tight. Beware "muffin top."
