Here's our list of 31 abs and core exercises, designed to strengthen and tone your abs. The exercises range from static holds, like the plank, to dynamic movements like bicycle crunches, V-ups and leg raises.

Most abs exercises can be done with an exercise mat, although it's useful to have a stability ball and medicine ball on hand. The hanging leg raises will also need a pull-up bar.

Our list is sorted by popularity from most popular to least popular, based on how many times each exercise is viewed on the web.

Abs muscles

The abs and core exercises in this guide work 4 muscle groups. The primary target is your rectus abdominis and the external and internal obliques. Secondary muscles include your hip flexors and erector spinae.

  • Rectus abdominis - This is the big muscle that extends along the front of your abdomen. It's known as the "six-pack" muscle because, when toned, it appears to have a segmented appearance. Your abs are responsible for flexing your spine by connecting you to your ribs. It's the key muscle engaged when doing crutches.
  • Obliques - The obliques are located on either side of your rectus abdominis. The external oblique is on the front of your abdomen, with the internal oblique lying beneath it. The obliques help you rotate your trunk and flex your spine from side to side. Exercises like bicycle crunches and side planks specifically engage your obliques.
  • Hip flexors - Your hip flexors help to flex your hips and are key muscles in exercises like leg raises and V-ups.
  • Erector spinae - This group of muscles runs along your back from your hips to your head. They help you maintain posture and are particularly engaged in exercises like the plank.

1. Crunches

diagram - How to do a crunch

While some abs exercises, like sit-ups, engage your entire core, abs crunches specifically target your upper abs. This makes crunches an excellent choice for sculpting the upper part of your abs.

Crunches can help you improve your core strength, which is essential for core balance and stability. A strong core can help with your functional fitness and reduce the risk of back pain or injuries.

How to do

  1. Lie flat on your back with your knees bent. Your feet should be flat on the floor.
  2. Place your hands behind your head, but avoid pulling on your neck.
  3. Lift your upper body towards your knees by engaging your core. Ensure your lower back stays on the floor.
  4. Finally, slowly lower back to the starting position.

2. Russian Twist

The Russian Twist involves a twisting motion of your torso that works your internal and external obliques. Training your obliques is as important as training your abs.

Strong obliques help with your posture and reduce your risk of back injuries. They can also improve your performance in everyday activities and sports, like tennis, golf or dancing.

How to do

  1. Sit on the ground with your knees bent.
  2. Lean back a few inches while keeping your back straight.
  3. Lift your feet slightly off the ground and keep them elevated throughout the exercise.
