Muscles Worked by the Abdominal Crunch

Muscles Worked by the Abdominal Crunch

Working and training your core muscles is not child’s play. It will only be possible once you perform the abdominal crunches correctly.

The primary muscles targeted by this exercise are the rectus abdominis, transverses abdominus, and obliques. Let us learn about these muscles in detail.

The rectus abdominis muscle is also known as the abdominal muscle. It is a paired muscle that runs vertically on each side of the anterior wall of the human abdomen. It is responsible for moving the body between the pelvis and the ribcage.

The transverses abdominus is a flat abdominal muscle that is under the internal abdominal obliques. It is used to support the lumbopelvic region. Think of this muscle as a corset that supports the internal organs. It stabilizes the pelvis and lumbar spine to avoid any improper movements.

Lastly, the obliques are on the sides of the abdominals and stretch from the hips to the rib cage. It is made up of two muscles: internal obliques and external obliques. This muscle helps with the aesthetic part of your body along with your posture. It also helps in preventing any injuries in the lower back or shoulders.

How to Perform the Abdominal Crunch?

As abdominal crunches are central to all kinds of physical exercises, it is imperative that you do them correctly. Go according to the following steps, and you will not make any mistakes:

  1. Lie on your back on the floor. You can use a yoga mat for more comfort.
  2. Bend your knees and keep your feet firmly on the floor.
  3. You can either keep your hands behind your head, on your chest or sideways. Some even prefer putting their arms forward in such a way that they are parallel to the quadriceps. As this is a personal choice, go with something that suits you the most.
  4. Pull your belly button towards your spine and get ready for the exercise.
  5. Keeping your abs tight, curl up while pushing your shoulder blades a few inches above the ground. Exhale while curling up.
  6. Keep your abdominals pulled in, and your chin slightly bent.
  7. Hold the position for one to two seconds and lower back down.
  8. Do not allow your body to relax while it touches the ground.
  9. Once you reach your starting position, repeat the process.

 

Common Mistakes to Avoid While Performing Abdominal Crunch

Common Mistakes to Avoid While Performing Abdominal Crunch

If you want to train your muscles properly, you must avoid the following mistakes while performing the abdominal crunches:

Perform on a Flat Surface

Ab crunches will require you to pull into your abs throughout the movements. A flat surface is a prerequisite for that. Do not try to perform this exercise on a soft or wobbly surface.

You can either do it on the floor, on a mat, or even on a flat bench.

 

Keep your Back Straight

When you lie down on the floor, it should touch the ground entirely. If we paraphrase it, there should be no gap between the ground and the lumbar spine. Keep it flat on the floor throughout the exercise.

 

Neck Flexing

When you curl up, your neck should remain in the original alignment. If you flex it or bend it forward, you might go home with a strained neck. Instead of moving your neck, you must only tilt your chin.

 

Shoulder Rolling

Along with the prohibited neck movement, your shoulder blades must never roll forward.

 

Range of Motion

An improper range of motion can negate the entire benefit of this exercise. Curl only till you contract your muscles. Curling anything more than that will not help you train your ab muscles.

 

Resting on the Floor

You are not supposed to rest on the floor after one rep. The tension in the abs must remain throughout the entire set. Never lose the tightness in the abs, or else your abdominal muscles will not get trained, even after 100s of sets.

 

Sets, Reps, Programming Recommendations for Abdominal Crunch

Doing this exercise alone will not get you abs. So if you believe that performing fifty reps of this exercise will build your abs, you are highly mistaken.

We recommend four sets of ten reps each. This will give you enough energy and time to perform other abdominal exercises.

  1. Bicycle Crunch
  2. V-sit Crunch
  3. Standing Crunch
  4. Cross Sit-up
  5. Kickboxing Crunch

  2. Maintain a proper form while contracting as well as while returning to the starting position.
