The Sexy S Factor Workout Amy Adams Loves

Amy Adams is already having an incredible year, thanks to a Golden Globe win and an Oscar nomination for American Hustle, a critically-acclaimed role in Her, a Man of Steel sequel in the works, and-if that's not enough-a sizzling W Magazine February Movie Issue cover.

In addition to this red-hot career, the 39-year-old actress has one hot, healthy bod. Aside from sweating up a storm with trainers like Tracy Anderson and Jason Walsh, Adams has been a fan of Sheila Kelley's exotic dancing-inspired S Factor since 2010. "Some mom friends said it's a good way to lose the baby weight," Adams told Marie Claire. "And I'll do anything to get off that treadmill!"

For a sample of the star's S Factor routine, try these sultry, signature moves from Kelley. "This is a workout that doesn't feel like work," Kelley says. "This is movement you can fall in love with, and it will boost your confidence and energy, and inspire you to love yourself more unconditionally." The routine also tones muscle, increases flexibility, and burns calories. Get ready to unlock your inner erotic self!

How it works: Complete the following exercises back to back with no rest.

You will need: Yoga mat

Bridge Grind

Sets: 2

Reps: 10 (5 in each direction)

Works: Butt

Lie faceup on a mat with knees bent and feet flat about hip-width apart. Rest arms out to the sides. Take a long, deep inhale as you lift hips so body forms a straight line from shoulders to knees. Exhale and squeeze butt simultaneously. Move hips in a circular motion in a clockwise direction, like you're scraping the inside of a tube with your hips, pushing out and down to the bottom until butt is centimeters away from touching the mat, then back up. Relax butt and take another long, deep inhale. Squeeze your butt again, exhale gradually, and pump hips up and down a couple inches 5 times. That's one rep. Repeat, moving hips counterclockwise.

Writhing to Prancing Goddess

Sets: 1

Reps: 90 seconds

Works: Abs

1. Lie faceup on a mat, legs together, feet and toes pointed, and arms out to the sides. Arch back, lifting chest up toward the ceiling, keeping head on the mat. Lift legs slightly off the ground. Bend knees at slightly different angles so right knee is a bit higher than left. Slowly switch knees so left is higher than right. Continue switching (writhing), toes and feet pointed, for 45 seconds.

2. With right knee higher than left, lift right leg until right thigh is perpendicular to the floor. Take a long, deep inhale and nearly straighten leg toward the ceiling. (Leave a sexy, subtle curve in it.) Exhale, and slowly lower right leg as you lift and straighten left leg while bending right knee. Move continuously with tummy tucked, going slowly to create resistance as if you're riding a bicycle on a sandy beach. Repeat for 45 seconds.

Standing Hip Circles

Sets: 1

Reps: 10 in each direction standing; 5 in each direction squatting

Works: Legs

Stand with feet slightly wider than hip-width apart, knees slightly bent. Make a wide, slow circle with hips moving clockwise 10 times. Repeat moving hips counterclockwise. Circle again clockwise, speeding up as you squat all the way down, bending knees slowly. Once at the bottom, slowly begin to straighten legs back to starting position with knees slightly bent, continuing to circle hips. Do 5 reps, then repeat 5 times moving hips counterclockwise.
