Crunches

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.

Twists and obliques

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.
  4. With your hands clasped in front of your chest, twist your torso to the right. Try to touch the ground with your elbow.
  5. Now, twist back over to your left.
  6. Repeat for the desired number of reps.

Planks and static holds

Unlike other abs exercises that involve a dynamic movement, like crunches or sit-ups, planks are an isometric exercise. That means you simply hold the same position for between 30 seconds and 2 minutes, and potentially longer.

The static hold nature of the plank engages multiple muscle groups simultaneously and improves your overall stability and posture.

How to do

  1. Start in the push-up position on the floor.
  2. Bent your elbows 90 degrees and rest your body weight on your forearms. Your elbows should be beneath your shoulders, with your body forming a straight line from head to toe.
  3. Hold the position for as long as you can, ideally at least 30 seconds.

Dynamic exercises

The Mountain Climbers exercise is a dynamic exercise that engages multiple muscle groups at the same time. Unlike traditional abs exercises that isolate your abs and obliques, this exercise benefits your overall strength. It's also an intense workout, so has some cardio benefits. If you follow a HIIT workout, Mountain Climbers is a good exercise to perform.

In addition to your abs and obliques, Mountain Climbers also works your quads and hip flexors.

How to do

  1. Start in a high plank position. Your hands should be under your shoulders, and your legs should be extended behind you.
  2. Engage your core and keep your back flat.
  3. Bring your right knee towards your chest. Avoid lifting your hips or allowing your foot to touch the floor.
  4. Now return it back to the starting position. At the same time, bring your left knee towards your chest.
  5. Continue alternating between your left and right legs, moving as quickly as you can.

Lower abs

  2. Extend your legs out and lift your heels about 6 inches off the floor.
  3. Make small and rapid movements up and down with your legs. Focus on engaging your abs through this movement.

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.
