graphic 1 highlighting all muscles used to engage your core

If you’ve been to any kind of fitness class or session with a personal trainer, we can almost guarantee that you’ve been told to ‘engage your core’ at some point during a workout. But do you actually know how to engage your core?

Engaging the core is quite possibly the most misunderstood and incorrectly executed of muscle actions. Most people think that you can engage your core by sucking in the stomach or tensing a six-pack, but that isn’t it.

That doesn’t mean that it is necessarily complicated or even remotely difficult to engage your core, once you know what you’re doing of course! We’re going to take you through everything you need to know, including:

  • What muscles is the core made up of?
  • How to engage your core
  • Why you need to know how to engage your core
  • Exercises which will strengthen and engage your core

What muscles is the core made up of?

In order to understand how to engage your core muscles, it is helpful to know which muscles the core is made up of and what they do.

When most people think of their core, they immediately think of the rectus abdominis or ‘six-pack’.  But there is more to both the abdominal muscles and a strong core than a chiselled six-pack. The core refers to all of the muscles which wrap around the torso and support both the pelvis and the spine, such as:

  • Glute muscles
  • Adductor muscles
  • Lower back muscles
  • Abdominal muscles and hip flexors (including the pelvic floor)
  • Spinal erectors
  • Diaphragm

Within this group of muscles, the abdominal muscles (including the rectus abdominis) are particularly important in understanding how to engage your core. The abdomen is made up of 4 sections of muscle: the transverse abdominis (TVA), the internal and external obliques and the rectus abdominis. 

The TVA is the deepest section. It wraps around the waist, and acts as a stabiliser for the lower back and the core muscles, connecting the ribcage to the pelvis. On top of the TVA are the internal and external obliques. The internal and external obliques are shaped in a criss-cross across the torso and help with twisting movements. The rectus abdominis, otherwise known as the six-pack, is the anterior section of abdominal muscles which helps the upper body to bend forward.

So, what does it mean to engage your core?

Your core is engaged when all 4 sections of abdominal muscle are braced together and working with the muscles that are connected to your spine to stabilise the torso. When you know how to engage your core correctly, you will be able to stiffen your torso to support your spine whilst it bends and twists.

How to engage your core

The simplest way to engage your core is to brace yourself as if you’re expecting a strong punch to the torso, and then breathe into your stomach. Your core engages naturally right before you laugh or cough, so if you initiate one of these actions, you’ll get an idea of how it should feel when your core is engaged.

Sucking in your stomach and holding your breath are the most common mistakes people make when told to engage their core. Truthfully, this is pretty much the exact opposite of how to engage your corecorrectly.

Rather than sucking your stomach in, you need to focus on pulling your navel up and in towards your spine. When you do this, your abs should feel tightened but you should still be able to move and breath as normal.

A good position for engaging your core is on all fours. In this position, pull your abs up and in towards your spine and keep your torso still whilst you exhale.

Focusing on your breathing is a really important part of how to engage your core correctly. You can’t engage your core whilst holding your breath, so it’s important to keep breathing normally whilst holding your abs. The TVA engages naturally as you exhale, so you can use your breath to engage your core every time you exhale. If you pull your navel up and in during the exhale, the movement should naturally pull your stomach in and lift your torso. 

Whilst breathing is an important part of engaging your core, it is important that you breathe normally to support your core. Deep belly breathing is not appropriate if you want to know how to engage your core while sitting, standing, walking or exercising in general.

Why you need to know how to engage your core

Now you know how to engage your core muscles, you might be wondering why you should do this. 

Your core is the basis of pretty much all of your movement, so a strong core benefits your athletic ability, flexibility, and overall strength. 

When your PT or fitness instructor is shouting for you to “engage your core”, it’s because they want you to get the most out of your workout. By engaging your core during an abdominal workout, like sit-ups or the plank, you ensure that you’re working the muscle you’re supposed to be – the abs. In this sense, engaging your core makes your workout more effective which ultimately leads to quicker and better results.

Having a strong core will benefit your progress when training other muscles too. An engaged core makes it easier to activate different muscles during exercise.

As well as increasing performance, another benefit of knowing how to engage your core correctly is that it helps to reduce the risk of injury.

When the core muscles work together, they support the spine which keeps the back safe from strain. For example, if you don’t know how to engage your core correctly when weight training and you become tired, your back will naturally start to arch. Engaging your core correctly whilst lifting will stop your back from arching which will prevent the back from becoming strained and potentially injured.

Engaging your core also allows your torso to transfer power from the lower to the upper body and back again during exercise. For example, engaging your core adds power to a cross punch in boxing as the move starts at the feet and moves through the pelvis to the upper body. 

A strong core is also good for your posture. When all of the core muscles are braced together, they keep your posture tall. This is another way in which knowing how to engage your core can help you to prevent an exercise-related injury. For example, if you understand how to engage your core while running, you can stop your back from arching which often causes back pain if persistent during such high-impact exercise. 

Having a weak core can cause postural deviation which can lead to general aches and pains as well as an extensive list of further negative effects and injuries. This includes reduced flexibility and injuries to the back, such as a slipped disc, as well as injuries to the rest of the body, for example, runner's knee.

Exercises which will strengthen and engage your core

Now that you know how to engage your core, and you’ve read all of the benefits of a strong core, here are a few exercises you can do to strengthen and engage your core muscles.
