“I already do planks and crunches. Isn’t that enough?”
It’s a question many people ask as deep core exercises become a bigger part of fitness conversations. After all, if you’re already training your core, why would you need to focus on something called the deep core?
The answer lies in understanding that your core is more than the muscles you can see. Beneath the muscles most people associate with core training is another group that quietly supports the way your body moves every day.
That’s why deep core exercises have become an important part of building strength that goes beyond appearance. They’re designed to improve the stability and control your body relies on during everyday activities as well as during exercise. Rather than replacing traditional core workouts, they complement them by strengthening the muscles that support stability and movement.
In this collaborative guide, the Leading Edge team has partnered with Marlene Handler, OTR/L, TIPHP, CSOT – Occupational Therapist and Founder of The Lifted Lotus – to bring together expertise in fitness and women’s pelvic health. The Lifted Lotus is a Brooklyn-based, occupational therapy-led pelvic health and women’s wellness practice in Williamsburg, offering pelvic floor therapy, private Pilates, and massage under one roof. Unlike traditional PT-led models, The Lifted Lotus takes an occupation-centered, trauma-informed approach – treating the pelvic floor not in isolation, but as part of how you move, breathe, and function in everyday life.
Together, we’ll break down what the deep core actually is, why it’s foundational to long-term health (not just performance), and the exercises that help you build a stronger, more connected foundation for the way you move every day.

What Makes the Deep Core Different From the Core You Already Know?
When most people think about their core, they picture the muscles that become stronger through planks, crunches, or sit ups. Those muscles are certainly part of your core, but they aren’t the whole picture.
Your core is made up of multiple muscles, each with a different job. The muscles closest to the surface help create movement and generate force. Beneath them is another group of muscles, often referred to as the deep core, that works to stabilize your spine, support your posture, coordinate with your breathing, and prepare your body for movement before it even begins.
A simple way to think about it is this: before you lift a heavy grocery bag, step off a curb, or change direction during a workout, your body first creates stability. Your deep core is part of that process, helping your body stay balanced and controlled so movement feels efficient rather than strained.
This doesn’t mean traditional core exercises have no place in your routine. In fact, they’re an important part of building strength. The difference is that a well rounded core training program develops both the muscles that create movement and the muscles that support it. Focusing on one while overlooking the other can leave an important part of your core undertrained.
“The deep core and outer core aren’t meant to work separately. They support each other, helping you build strength that’s useful not only during workouts but also in everyday life.” — Marlene Handler, OTR/L, TIPHP, CSOT
The Benefits of Core Strength in Everyday Life
When people think about the benefits of core strength, they often picture better workouts or stronger abdominal muscles. In reality, one of the greatest benefits is something far less obvious: it improves the quality of the movements you make every single day. A strong core doesn’t just help you exercise better. It helps your body move with greater stability, control, and confidence throughout everyday life.
Your core isn’t only active during structured workouts. It’s working when you get out of bed, climb stairs, reach for something on a high shelf, bend down to tie your shoes, or play with your children. These everyday movements may seem simple, but they all depend on your body staying stable and coordinated. A strong core provides that support, allowing the rest of your body to move with greater stability and control. A review published in Current Sports Medicine Reports explains that the muscles of the core work together to provide spinal stability, which is essential for functional movement.
This is why core strength is often described as the foundation of movement rather than simply another fitness goal. Before your arms lift, your legs push, or your body changes direction, your core helps create the stability those movements depend on. When that stability is strong, movement feels more natural because your body isn’t relying on other muscles to compensate. Whether you’re beginning a strength training program or simply looking to move more comfortably throughout the day, a strong deep core provides the stability needed for safer, more efficient movement.
The benefits of core strength become even more valuable over time. Good stability, balance, and movement quality can help you stay active and independent as you age, whether your goal is to enjoy recreational activities, continue exercising, or simply move through daily life with greater confidence and ease.
How to Activate Your Deep Core Before You Strengthen It
One of the biggest misconceptions about deep core exercises is that they’re simply more difficult versions of traditional ab workouts. In reality, effective deep core training isn’t about doing harder exercises. It’s about learning to activate the right muscles before movement begins.
Unlike exercises that primarily target the outer abdominal muscles, deep core training focuses on controlled breathing, proper alignment, and slow, intentional movement. These fundamentals help your body create the stability it needs before generating force through your arms or legs. Rather than focusing on intensity, the goal is to build better control from the inside out.
Think about picking up a heavy box from the floor. Before your hands even lift the weight, your body naturally prepares by creating stability around your spine and pelvis. The same principle applies during deep core exercises. The focus isn’t simply on making your abdominal muscles work harder, but on teaching the muscles responsible for stability to activate at the right time and work together efficiently.
This approach also explains why deep core training often feels different from traditional core workouts. The movements may appear slower or less intense, but they require concentration and coordination. By practicing controlled movement instead of relying on momentum, you develop a stronger foundation that supports everything from everyday activities to more challenging workouts.
If you’re unsure whether you’re activating the right muscles, working with a trainer through virtual personal training can provide expert guidance and real-time feedback, helping you build proper technique from the very beginning.
Marlene Handler shares: “Many people rush through exercises in an effort to feel a stronger burn, but deep core training rewards control rather than speed. Learning to activate these muscles correctly creates a stronger foundation for every exercise that follows, making the quality of each movement far more important than the number of repetitions you complete.”
Deep Core Exercises You Can Add to Your Routine
Now that you understand what the deep core is and why it matters, it’s time to put that knowledge into practice. These deep core exercises are designed to improve stability, coordination, and control, helping you build greater stability for both everyday movement and exercise. Focus on slow, deliberate movements and proper breathing rather than speed or high repetitions.
1. Dead Bug
The Dead Bug is one of the most effective deep core exercises for improving spinal stability and coordination. It teaches your core to stay engaged while your arms and legs move independently.
How to do it:
- Lie on your back with your knees bent at 90 degrees and your arms extended toward the ceiling.
- Engage your core and gently press your lower back into the floor.
- Slowly lower your opposite arm and leg toward the floor.
- Return to the starting position and repeat on the opposite side.
- Complete 8 to 12 repetitions per side.
2. Bird Dog
The Bird Dog helps improve balance, coordination, and core stability by encouraging your core, hips, and back muscles to work together.
How to do it:
- Begin on your hands and knees with your back in a neutral position.
- Extend your opposite arm and leg until they are parallel to the floor.
- Pause briefly before returning to the starting position.
- Repeat for 8 to 12 repetitions on each side.
3. Glute Bridge
The Glute Bridge strengthens your glutes while activating the deep core muscles that help stabilize your pelvis and lower back.
How to do it:
- Lie on your back with your knees bent and feet flat on the floor.
- Tighten your core and lift your hips until your body forms a straight line from your shoulders to your knees.
- Lower slowly and repeat 10 to 15 times.
4. Side Plank
The Side Plank targets the muscles along the sides of your core, helping improve trunk stability and overall balance.
How to do it:
- Lie on your side with your forearm directly beneath your shoulder.
- Lift your hips until your body forms a straight line.
- Hold for 20 to 30 seconds before switching sides.
- If needed, keep your lower knee on the floor for additional support.
5. Heel Taps
Heel Taps strengthen the deep abdominal muscles by encouraging controlled movement while keeping your core engaged throughout the exercise.
How to do it:
- Lie on your back with your knees bent at 90 degrees.
- Keeping your core engaged, slowly lower one heel to tap the floor.
- Return to the starting position and alternate sides.
- Perform 10 to 12 repetitions per side.
“Building a stronger core isn’t about choosing the most advanced exercises or rushing through repetitions. It’s about developing better movement patterns over time. Performing these exercises consistently with proper breathing, control, and technique will have a greater impact than doing more with poor form.” says Marlene
Common Mistakes to Avoid During Deep Core Exercises
Learning a few deep core exercises is a great start, but how you perform them matters just as much. It’s easy to fall into habits that make these movements less effective, especially if you’re used to traditional core workouts. Paying attention to your technique will help you get more from every exercise while building strength safely over time.
Rushing Through Each Movement
It’s easy to think that moving faster means you’re getting a better workout. However, deep core exercises are designed to be slow and controlled. Taking your time allows the right muscles to engage and helps you build the stability these exercises are meant to develop.
Holding Your Breath
Many people hold their breath without realizing it, especially during more challenging movements. Instead, try to breathe naturally throughout each exercise. Steady breathing works together with your core muscles to support better control and stability.
Focusing on Repetitions Instead of Form
More repetitions don’t always lead to better results. A few well-controlled movements with proper technique are often far more beneficial than rushing through a longer set with poor form.
Progressing Too Quickly
Once an exercise starts to feel comfortable, it’s tempting to move on to more advanced variations. Building a strong foundation takes patience, and mastering the basics first will prepare your body for greater challenges while reducing the risk of developing poor movement habits.
“One of the biggest misconceptions about deep core training is treating it like a traditional abdominal workout,” says Marlene. Instead of chasing a stronger burn or completing more repetitions, focus on moving with intention, maintaining steady breathing, and building control. Over time, those small improvements in technique can make a meaningful difference in how your body moves both during exercise and in everyday life.”
Building a Strong Core for Better Health
Building a stronger core isn’t about finding the most challenging exercise or completing the highest number of repetitions. It’s about developing strength that supports better movement, improved stability, and long term physical health. A well-trained deep core supports better movement, improves stability, and helps you stay active with confidence through every stage of life.
The most important step is simply getting started. Consistently practicing deep core exercises with proper form, steady breathing, and controlled movement can improve your stability, support better posture, and help you build lasting strength over time. Small improvements made today can contribute to better movement and overall health for years to come.
