A strong core is essential for overall fitness, stability, and injury prevention. Whether you’re aiming for a defined six-pack or just looking to improve functional strength, ab exercises should be a key part of your workout routine. Below are 15 of the most effective ab exercises that target all areas of your core.

1. Plank

The plank is a core staple that works your entire midsection. By maintaining a straight body line and keeping tension in your abs, you engage your transverse abdominis, which helps stabilize your spine.

How to do it:

  • Start in a push-up position, with your forearms on the ground.
  • Keep your body in a straight line from head to heels.
  • Hold this position for 30 seconds to a minute, gradually increasing as you get stronger.

2. Bicycle Crunches

Bicycle crunches are great for targeting both your upper and lower abs, while also engaging your obliques.

How to do it:

  • Lie flat on your back with your hands behind your head.
  • Lift your legs off the floor and bend them at a 90-degree angle.
  • Bring one knee toward your chest while simultaneously twisting your torso and bringing your opposite elbow to meet that knee.
  • Alternate sides in a “bicycling” motion.

3. Russian Twists

Russian twists primarily target the obliques but also engage the lower abs.

How to do it:

  • Sit on the ground with your knees bent and lean back slightly.
  • Hold a weight or medicine ball and twist your torso from side to side, touching the weight to the ground next to your hip on each side.

4. Leg Raises

Leg raises are ideal for working the lower abs, which can be challenging to target effectively.

How to do it:

  • Lie on your back with your legs straight.
  • Slowly raise your legs up toward the ceiling, keeping them as straight as possible.
  • Lower them back down slowly, stopping just above the floor to maintain tension.

5. Mountain Climbers

Mountain climbers are a dynamic exercise that combines cardio with core strengthening, focusing on the abs.

How to do it:

  • Start in a high plank position with your hands shoulder-width apart.
  • Bring one knee toward your chest, then quickly switch legs in a running motion.

6. V-Ups

V-Ups target both the upper and lower abs in one fluid motion, improving overall core strength.

How to do it:

  • Lie flat on your back with your arms extended overhead.
  • Simultaneously lift your legs and torso to form a “V” shape, reaching your hands toward your feet.

7. Reverse Crunch

The reverse crunch emphasizes the lower abs and helps build strength in that hard-to-reach area.

How to do it:

  • Lie on your back with your legs bent and knees at a 90-degree angle.
  • Lift your hips off the ground, bringing your knees toward your chest.

8. Flutter Kicks

Flutter kicks work the lower abs and help improve hip flexor strength.

How to do it:

  • Lie on your back with your hands under your glutes for support.
  • Keep your legs straight and lift them a few inches off the floor.
  • Alternately kick your legs up and down in a controlled motion.

9. Toe Touches

Toe touches target your upper abs while also engaging your obliques and lower abs for stabilization.

How to do it:

  • Lie on your back with your legs extended straight up toward the ceiling.
  • Reach your hands up to try and touch your toes, engaging your core.

10. Side Plank

Side planks focus on your obliques and also improve overall core stability.

How to do it:

  • Lie on your side and lift your body up onto one forearm.
  • Keep your body in a straight line and hold for 30 seconds to a minute, then switch sides.

11. Dead Bug

The dead bug is excellent for teaching core stability and coordination, hitting the deeper core muscles.

How to do it:

  • Lie on your back with your arms extended straight up and your legs lifted in a tabletop position.
  • Lower your right arm and left leg simultaneously, keeping your lower back pressed into the ground.
  • Return to the starting position and switch sides.

12. Hanging Leg Raises

For advanced core strength, hanging leg raises are highly effective at hitting your lower abs.

How to do it:

  • Hang from a pull-up bar with your arms fully extended.
  • Slowly lift your legs straight up toward your chest, then lower them with control.

13. Cable Crunch

The cable crunch adds resistance to your ab workout and helps you build stronger muscles.

How to do it:

  • Kneel in front of a cable machine with a rope attachment.
  • Hold the rope behind your head and crunch down, bringing your elbows toward your thighs.

14. Standing Oblique Crunch

This standing exercise helps strengthen your obliques while also improving balance.

How to do it:

  • Stand with your feet shoulder-width apart and hands behind your head.
  • Lift one knee toward your elbow while bending sideways, engaging your obliques.
  • Alternate sides.

15. Spiderman Plank

Spiderman planks add an extra challenge to the traditional plank by engaging your obliques and hip flexors.

How to do it:

  • Start in a high plank position.
  • Bring one knee to the outside of your elbow, then return to the plank position.
  • Alternate sides.
