A Comprehensive Guide to Engaging Your Core

Strengthening your core is essential for overall fitness and stability. Whether you’re a fitness enthusiast or just starting your fitness journey, engaging your core should be a top priority in your workouts. Your core muscles, which include the abdominal, obliques, and back muscles, play a crucial role in maintaining good posture, preventing lower back pain, and improving athletic performance.

Why is engaging your core so important?

Engaging your core is more than just getting a six-pack. Strong core muscles are the foundation of every movement you make. They provide stability and control during everyday activities and sports performance. Additionally, a strong core can help improve your balance and prevent injuries by supporting your spine and pelvis.

So, how do you engage your core?

First and foremost, it’s important to understand what it means to engage your core. This involves contracting and activating the muscles in your abdomen and lower back. One way to engage your core is by drawing your belly button in towards your spine. Imagine pulling your belly button towards your back while maintaining a neutral spine. Another effective technique is the plank exercise, which requires you to hold a straight-line position while engaging your core muscles.

Rectus Abdominis

The rectus abdominis is a paired muscle that runs vertically along the anterior wall of the abdomen. It is commonly referred to as the “six-pack” muscle, as it is responsible for the defined appearance of the abdominal muscles in individuals with low body fat.

The rectus abdominis originates from the pubic crest and symphysis and inserts into the xiphoid process and the costal cartilages of ribs 5-7. It is divided into two halves by a band of connective tissue called the linea alba.

This muscle plays a key role in core stabilization and the movement of the trunk. Its primary action is flexion of the lumbar spine, which is commonly referred to as “crunching” or “sit-ups”. Additionally, it assists in forced expiration, such as during coughing or sneezing.

To effectively engage the rectus abdominis, exercises such as crunches, sit-ups, and planks can be performed. It is important to maintain proper form and alignment during these exercises to prevent strain or injury.

Targeting the rectus abdominis can help improve overall core strength and stability, as well as contribute to a toned and defined midsection.

Internal and external obliques

The internal and external obliques are muscles located on the sides of the abdominal region. They are considered to be essential for core strength and stability. Here are some key points to know about these muscles:

  • The internal obliques are positioned underneath the external obliques and run in the opposite direction. They originate from the iliac crest and the thoracolumbar fascia, and insert into the lower ribs, linea alba, and pubis. Their main function is to rotate and bend the trunk.
  • The external obliques are the most superficial muscles of the lateral abdominal wall. They run diagonally and originate from the lower eight ribs, inserting into the iliac crest and the linea alba. Their main function is to flex and rotate the trunk.
  • Both the internal and external obliques work together to provide stability to the core during various movements and activities. They play a crucial role in activities such as lifting, twisting, and bending.
  • Weakness or imbalances in the oblique muscles can lead to lower back pain, poor posture, and a lack of core stability. It is important to engage and strengthen these muscles through targeted exercises.
  • Some exercises that specifically target the oblique muscles include side plank, Russian twists, bicycle crunches, and woodchoppers. These exercises can be incorporated into a comprehensive core workout routine.
  • Engaging and strengthening the oblique muscles can improve overall core strength and stability, enhance athletic performance, and reduce the risk of injury during physical activities.

Overall, the internal and external obliques are important muscles for core strength and stability. Incorporating exercises that target these muscles into your fitness routine can have numerous benefits for your overall health and well-being.

Transversus abdominis

Transversus abdominis

The transversus abdominis is a deep abdominal muscle that plays a crucial role in core stability and posture. It is located beneath the rectus abdominis and internal oblique muscles.

This muscle runs horizontally across the abdomen and functions like a corset, providing support and compression to the abdominal contents. It acts as a natural weight belt that helps stabilize the spine and pelvis during movement. The transversus abdominis is often referred to as the “corset muscle” because of its role in providing a slimming effect on the waistline.

Engaging the transversus abdominis is essential for maintaining a strong core and preventing injury. To activate this muscle, it is important to focus on drawing the navel towards the spine, feeling a deep contraction in the lower abdomen. This can be done during various exercises, such as planks, squats, and deadlifts.

Strong transversus abdominis muscles can improve overall posture, reduce back pain, and enhance athletic performance. It is important to include exercises that target this muscle in your fitness routine to ensure a well-rounded core workout.

In summary, the transversus abdominis is a deep abdominal muscle that plays a vital role in core stability. Engaging this muscle is crucial for maintaining a strong core and preventing injury. Including exercises that target the transversus abdominis in your fitness routine can help improve posture, reduce back pain, and enhance overall athletic performance.

Pelvic floor

Pelvic floor

The pelvic floor is a group of muscles that span the area between the pubic bone and the tailbone. It acts as a support system for the organs in the pelvis, including the bladder, uterus, and rectum.

Engaging the pelvic floor muscles is an essential part of core engagement. These muscles play a crucial role in stabilizing the pelvis, maintaining good posture, and preventing issues such as incontinence.

To engage your pelvic floor, imagine that you are stopping the flow of urine midstream. This sensation can help you activate the correct muscles. Once you have identified the pelvic floor muscles, squeeze them gently and hold for a few seconds before releasing. Repeat this contraction and release exercise several times.

Regularly engaging your pelvic floor can help improve bladder control, as well as enhance sexual function. It can also prevent problems associated with weakening pelvic floor muscles, such as pelvic organ prolapse.

It is important to note that while engaging the pelvic floor muscles, you should also be mindful of maintaining relaxation in the rest of your body, especially the abdomen. Holding your breath or contracting other muscles too tightly can interfere with proper engagement of the pelvic floor.

Additionally, it is beneficial to incorporate specific exercises that target the pelvic floor muscles into your fitness routine. These exercises, such as Kegels, can help strengthen and tone the pelvic floor over time.



The diaphragm is a dome-shaped muscle that separates the chest cavity from the abdominal cavity. It plays a crucial role in core engagement and breathing.

When you engage your core, the diaphragm contracts and flattens, creating tension in the abdominal muscles and providing stability to the spine. This activation of the diaphragm helps to support your posture and can improve your overall strength and balance.

In addition to its role in core engagement, the diaphragm is also responsible for the process of breathing. When you inhale, the diaphragm contracts and moves downward, creating a vacuum in the chest cavity. This vacuum allows air to flow into the lungs. When you exhale, the diaphragm relaxes and moves upward, expelling the air from the lungs.

Proper diaphragmatic breathing is essential for maximizing the benefits of core engagement. It allows you to fully engage the diaphragm and strengthen the surrounding muscles, which can improve your lung capacity and oxygen intake.

To engage your diaphragm and promote proper breathing, start by finding a comfortable position. Sit or lie down with your spine straight and your shoulders relaxed. Place one hand on your chest and the other hand on your abdomen.

As you inhale, focus on expanding your abdomen and feeling the air fill your belly. Your chest should remain relatively still. As you exhale, allow your abdomen to contract and gently push the air out of your lungs.

Practice diaphragmatic breathing regularly to improve your core engagement and overall breathing technique. Incorporate it into your workouts and daily activities to experience the full benefits of a strong and engaged core.

Back extensors

Strong back extensors are crucial for maintaining good posture and preventing lower back pain. These muscles, along with the core muscles, help support the spine and keep it stable during movement.

The main group of back extensor muscles is called the erector spinae. This group is made up of three muscles: the iliocostalis, longissimus, and spinalis. These muscles run along the length of the spine and play a major role in extending the back.

To engage your back extensors, try the following exercises:

  1. Superman: Lie face down on the floor with your arms extended in front of you. Lift your arms, chest, and legs off the ground as high as you can while keeping your neck in a neutral position. Hold for a few seconds and then lower back down.
  2. Back extensions: Lie face down on an exercise ball with your feet against a wall for stability. Place your hands behind your head or across your chest. Slowly lift your chest off the ball, squeezing your back muscles. Lower back down with control.
  3. Deadlifts: Stand with your feet hip-width apart and a barbell in front of you. Bend at the hips and knees, keeping your back straight, and grip the barbell with an overhand grip. Push through your heels and lift the barbell, engaging your back extensors. Lower the barbell back down with control.

Remember to start with lighter weights and gradually increase as your back extensors become stronger. Always maintain proper form and consult with a fitness professional if you have any concerns or questions.

Adding back extensor exercises to your core routine can help improve your overall core strength and stability, leading to better posture and reduced risk of lower back pain.
