Are planks good for abs? When it comes to ab exercises, planks are often mentioned and recommended alongside classic core workouts such as crunches and sit-ups. Despite their popularity as a core workout, how good are planks for abs and can they give you that enviable six pack that you have always dreamed about?


Are Planks Good For Abs Bodybuilding?

Yes, they are. According to, if you are looking to build your core then planks are the best thing for you. They actually rank higher than crunches and sit-ups in their effectiveness.

Why Are Planks Good For Your Abs?

Here are some reasons why planks are good for your abs:

  • They Workout Your Whole Core

When people think about the core, they are mostly imagining the front area of the stomach where the abs are often located. While this is indeed the core, it is only just a small part of it. The core is actually made up of several different muscles namely:

Transverse Abdominis

This is the deepest layer of muscle that extends from your torso to the pelvis. It works as a compression to the abdomen and all the internal organs in this area and also helps to stabilize your spine. BetterMe

Erector Spinae

Found on each side of your spine and they work to help with side to side movement as well as extending and rotating the back.

Obliques (External And Internal)

The external obliques lie on either side of our bodies right where the love handles should be/are. The internal obliques are located right under the external obliques, just inside the hip bones. These 4 muscles (two on either side) work together to help us bend sideways and twist our bodies from side to side.

Latissimus Dorsi

These are found behind you, just below the shoulder blades along the sides of your spinal cord. Like the obliques, they help us twist from side to side and also stabilize our backs.

Rectus Abdominis

Commonly known as abs, they are located between the ribs and the pubic bone at the front of the pelvis and their main function is to help us bend forward.

Planks unlike some other core workouts will exercise all these muscles at a go.


  • They Are Safer For Your Spine And Lower Back

The curling motion used when doing other core exercises such as crunches and sit-ups usually puts stress on your spine and lower back which can lead to chronic pain and injury. Planks on the other hand often require you to remain in one position with your back raised and spine aligned giving less chances for back injury.

  • They Are Easy To Modify

The standard plank is not the only variation there is. This simple, seemingly boring workout has many variations that still workout your core and prevent the boredom of doing the same thing over and over.

Helps With Low Back Pain

Chronic low back pain is one of the most common complaints about ailment in adults. In 2019 in North American alone, about 75 million people reported suffering from chronic low back pain (1). A 2018 study by the International Journal of Science and Research, revealed that planks, including side planks can help with the treatment and therapy of low back pain.

They Are A Full-Body Workout

As previously mentioned above, side planks exercise different muscles at once and so depending on your variation combinations, you can end up working out your whole body with one simple exercise.

Help Improve Balance And Coordination

They are known as balancing exercises and holding the original pose, let alone their variations is not an easy task.

Reduces The Risk Of Back Injury And Protects Your Spine

Many common and even easy-to-do workouts can be very dangerous for you, especially if you do not use the correct form. To prevent such injury, strengthening your core as well as the muscles surrounding the spine can help keep you safe.

One 2016 study by the International Journal of Sports Physical Therapy, showed that a weak core increases your risk of injury and plank exercises, including side planks, can help reduce this risk (2). A 2019 study showed that strengthening the quadratus lumborum – located in your lower back on either side of the lumbar spine – through workouts such as these helps to reduce your risk of a back injury (3).
