A Guide to Your Core Muscles

Updated: 5 days ago


Your core is much more than just your ab muscles—it’s the powerhouse that stabilizes and supports your body’s movements. Often referred to as your “trunk,” the core includes the muscles in your abdomen, back, and pelvis. A strong core is essential to moving well and feeling your best, while a weak core can lead to imbalances, poor posture, and even injury. Let’s break down the key muscles of your core and ways to keep them strong and flexible.


The Importance of Core Strength

Every movement you make involves your core. It stabilizes your spine and keeps excessive strain off your back, helping to protect you from injuries like back pain, hip pain, and muscle strains. A strong core also improves your balance and posture, supporting your body like the frame of a house.


Key Muscles of the Core

  1. Pelvic Floor: This supports the bladder, bowels, and reproductive organs in women. Weakness can cause incontinence, especially post-pregnancy.

  2. Abdominal Obliques: These side muscles allow you to twist and turn. They’re often strained in sports or activities involving rotation.

  3. Transverse Abdominis: The main stabilizer wrapping around your spine. Weakness here can lead to lower back pain.

  4. Rectus Abdominis: Known as the “six-pack” muscles, these help stabilize your core. Weakness or separation, common post-pregnancy, can cause diastasis recti.

  5. Erector Spinae: This deep back muscle keeps your spine straight. Weakness can lead to back pain and poor posture.


Core-Friendly Exercises

Try these exercises to build strength and flexibility in your core (Click on links for videos):

  • Cat-Cow Stretch: Mobilizes your spine, relieving tension.

    • Start on your hands and knees in a tabletop position. 

    • Inhale, arch your back, and lift your tailbone and head (cow pose).

    • Exhale, round your spine, tuck your chin to your chest, and tuck your tailbone (cat pose).

    • Repeat the sequence, moving smoothly between cat and cow poses to stretch and mobilize the spine.

  • Hip Flexor Stretch: Loosens up tight hip muscles.

    • Kneel on one knee with the other foot in front, creating a lunge position.

    • Keep your torso upright and press your hips forward, shifting your weight forward until you feel a stretch through the front of the left thigh and groin. 

    • Switch legs and repeat the stretch on the other side. 

  • Plank Variations: Strengthens your entire core.

    • Forward Plank. Start by positioning yourself on your forearms and toes on the floor, keeping your elbows directly below your shoulders. Gradually transition to a push-up position with arms fully extended. Hold your body in a straight line from head to heels, engaging in your core muscles throughout the exercise. 

    • Side Plank. Lie on your side with your legs straight and prop yourself up on your forearm, lifting your hips off the ground to form a straight line from head to heels. 

    • Dynamic Planks. Incorporate movement into your plank by lifting alternate limbs or performing plank jacks (moving your feet in and out like a jumping jack on the floor). 

  • Crunches: Target your rectus abdominis for core stability.

    • Lie on your back with your knees bent and feet flat on the floor. 

    • Place your hands behind your head or crossed over your chest. 

    • Lift your head and shoulders off the floor using your abdominal muscles while keeping your lower back on the ground. 

    • Lower back down with control and repeat the movement. 


If an exercise causes pain, stop and consult with a physical therapist. With regular practice and a mindful approach, your core will be your biggest supporter in everyday movements and overall health!
