For many women, achieving a lean midsection is no easy feat. Men and women’s muscles aren’t significantly different, but women tend to be wider through the pelvis and have a longer waist. This can make it challenging to get flat, firm abs.

But visible abdominal muscles aren’t impossible — you might just need to commit to doing more than standard sit-ups.

The best abdominal exercises for women target four muscle groups in your core:

  • External abdominal obliques. These are the
    muscles in your sides that you can feel just beneath your arms, along your
    ribcage.
  • Internal abdominal obliques. These are
    stabilizing muscles that lie underneath your external obliques.
  • Transversus abdominus. These are the
    deepest muscles. They run horizontally around your midsection.
  • Rectus abdominus. These muscles run
    from your sternum down to your pelvis. They help flex your spine as you walk.
    They’re also the most superficial muscles in your abdomen and the ones you see
    in “six-pack” abs.

To properly target and tone all four muscle groups, it’s important to perform a range of stabilization exercises. Training these core muscles will also stabilize your spine and pelvis to improve your posture and reduce or avoid back pain.

Unlike traditional crunches or sit-ups, stabilization exercises that target the core will work more muscles and burn more calories.

Complete these abdominal exercises two to three times a week for a stronger core.

  1. Stand
    up tall with your feet together and your core engaged.
  2. Bend
    at the hips and try to touch the floor. As soon as your fingertips hit the
    floor, walk your hands out until you reach a push-up position.
  3. Crawl
    your way back up to the starting position by inching your hands backward and
    piking your hips up to the ceiling. When your feet are flat on the floor, bend
    at the hips again and lift yourself back up to the standing position.

Advanced option

You can make this exercise harder by lifting one leg before walking your hands out.

Benefit

Using your arms and legs in this exercise adds intensity and resistance.

  1. Begin on your left side, with your elbow directly below
    your shoulder and your forearm perpendicular to your body.
  2. Stack your feet or place one in front of the other.
  3. Contract your abs and lift your hips off the floor
    until your body makes a diagonal line from your shoulder to your feet.
  4. Hold this position for 30 to 45 seconds.
  5. Switch sides and repeat.

Advanced option

Add hip dips for an extra challenge. Perform the same exercise for 30 to 45 seconds but continually dip your hips until you lightly tap the floor and then return to the starting position.

Benefit

Unlike a traditional plank, you’ll support your body weight on just two points of contact. This requires more work from your core to stay stable. Your back and abs work together to keep your spine elongated.

  1. Begin in a seated position, knees bent at 90-degree
    angles and feet flat.
  2. Reach your arms forward, palms facing each other.
  3. Exhale, pulling your belly button toward your spine.
  4. Roll back onto your tailbone, curving your spine into a
    C shape.
  5. Inhale and return to the starting position. Repeat,
    doing 15 more reverse crunches.

Advanced option

Try the same exercises, but rather then rolling back into a C shape, roll all the way back until you’re flat on your back.

Benefit

This exercise emphasizes the rectus abdominus.

  1. Begin by sitting upright with your knees bent and feet
    flat on the floor.
  2. Lean back, balancing on your sit bones and lift your
    legs off the floor.
  3. Extend your arms out straight, palms up. Your body will
    form a V shape.
  4. Hold for 30 seconds.

Advanced option

Transition into a low boat pose by dropping your feet to about six inches above the floor.

Benefits

This exercise focuses on your lower abs.

For this exercise, you’ll need space to move in and something that will slide easily across the floor. Try a towel on hardwood or tile floors, or a plastic bag or Frisbee on carpet.

  1. Begin in a plank position with your feet on a towel,
    bag, or Frisbee.
  2. Walk forward, using your hands only and dragging your
    lower body along for 10 to 20 yards.
  3. Keep your core and glutes tight as you move forward.
  4. Rest for a minute and then alligator drag back to where
    you began.
  5. Rest and repeat.

Advanced option

This one’s hard enough as it is!

Benefit

You’ll use your entire core for stability in this exercise. It also combines movement and resistance for added intensity.

Remember, exercises like these will help you strengthen your ab muscles and improve your posture. But according to Mayo Clinic, there’s no such thing as “spot reducing” fat in specific parts of your body.

That means you might not get six-pack abs even if you do hundreds of repetitions. Instead, work on reducing overall body fat by taking in fewer calories and sticking to a consistent exercise plan.
