What Is Good Core Exercises

I used to think that doing a few sit-ups after work was enough to keep my core strong. But about a year ago, after I started doing repetitive lifting at work, I felt a sharp pain in my lower back. It wasn’t just a twinge—it felt like something had shifted inside me. That moment made me realize that what I had been doing for years wasn’t enough. What is good core exercises, really? That’s the question I asked myself, and it changed everything.

Over the past few months, I’ve tried a wide range of core exercises, from basic planks to more advanced movements like dead bugs and leg raises. I’ve spent hours on YouTube, read through dozens of fitness blogs, and even bought a few online courses. But what stood out was that not all core exercises are created equal. Some focus on the wrong muscles, others are too easy or too hard, and many are just not practical for people with busy lives.

What I’ve learned is that good core exercises are about more than just crunches. They’re about stability, control, and balance. They’re about building a foundation that supports your entire body, not just your abs. So if you're asking, 'what is good core exercises,' I hope this article gives you a clear, actionable answer that you can start applying today.

Understanding the Core: More Than Just Abs

As of October 2026, the core is often misunderstood as being solely about the rectus abdominis—the ‘six-pack’ muscle. But in reality, the core is a group of muscles that includes the transverse abdominis, the obliques, the erector spinae, and the pelvic floor. These muscles work together to stabilize the spine and pelvis, allowing for efficient movement in all directions.

One of the most important muscles in the core is the transverse abdominis, which acts like a corset around the abdominal cavity. It’s responsible for maintaining intra-abdominal pressure, which helps support the spine during lifting and bending. If this muscle is weak, it can lead to lower back pain and instability.

I discovered this the hard way when I tried doing a basic plank and my lower back started to ache. It wasn’t because I was doing the exercise wrong, but because I wasn’t engaging my core properly. That’s when I realized the importance of understanding the core’s full function—not just how it looks, but how it works.

The Benefits of a Strong Core

I used to slouch at my desk for hours every day, and it took a toll on my posture. After starting a regular core routine, I noticed that my posture improved dramatically. Not only did I feel more confident, but I also experienced less fatigue throughout the day.

A strong core also helps prevent injuries, especially in the lower back. I remember reading a study that found individuals with regular core training had a 30% lower risk of developing chronic lower back pain. That number stuck with me, and I started making core exercises a priority in my fitness routine.^[1]

Another benefit I’ve noticed is improved athletic performance. Whether I was lifting, running, or even just walking, I felt more balanced and stable. It was like my body had a better foundation to work from.

A strong core is the foundation of every movement you make.

The Best Core Exercises for Beginners

When I first started exploring core exercises, I was overwhelmed by the sheer number of options. But I quickly realized that the key to success was starting simple and focusing on form. Exercises like the basic plank and bird dog were great for building foundational strength.

I remember doing the basic plank for the first time and barely making it through 30 seconds. My arms were shaking, and my lower back was aching. But over time, as I focused on engaging my core and maintaining proper alignment, I found that I could hold the plank for much longer.^[2]

The key takeaway here is that progress comes slowly and steadily. It's better to do a few repetitions with good form than to rush through a lot of them with poor technique.

Progressing to More Advanced Core Exercises

After a few weeks of basic planks and bird dogs, I was ready to challenge myself with more advanced movements. Exercises like the dead bug, side plank, and hollow body hold helped me build more comprehensive core strength.

The dead bug is one of my favorites because it requires control and coordination. It’s a great way to train the entire core while also engaging the glutes and lower back. I found that doing this exercise three times a week really improved my balance and stability.

Another advanced exercise I tried was the side plank. At first, I could barely hold it for 20 seconds. But with consistent practice, I was able to hold it for over a minute. The difference in my overall strength and stability was noticeable.

The Role of Breathing in Core Exercises

One of the most important things I learned about core exercises is the role of breathing. I used to hold my breath during planks and crunches, thinking it would help me stay stable. But I quickly learned that this was actually causing me to tense up and engage the wrong muscles.

Proper breathing involves inhaling through the nose and exhaling through the mouth, allowing the core to engage naturally. I found that when I focused on this technique, my form improved significantly, and I felt less strain on my lower back.

I now make a point to breathe deeply during all of my core exercises. It’s helped me stay focused, maintain better form, and avoid overexertion.

The Importance of Consistency in Core Training

I used to think that doing core exercises once or twice a week was enough. But I quickly learned that without consistency, progress was minimal. I started doing core exercises five times a week, and within two weeks, I noticed a significant improvement in my balance and stability.

One of the best things I did was set a daily goal for myself. Whether it was doing 10 planks or 20 crunches, I made sure to stick to it. It helped me develop a routine and build the habit of working on my core every day.

Consistency also helped me track my progress over time. I kept a log of how many reps I could do and how long I could hold each position. It was a great way to stay motivated and see how far I had come.

Consistency beats intensity every time.

Common Core Exercises and How to Do Them Correctly

One of the most effective core exercises is the basic plank. To do it correctly, start by placing your elbows directly under your shoulders and your feet hip-width apart. Keep your body in a straight line from head to heels, and engage your core by drawing your belly button toward your spine.

Another great exercise is the bird dog. It involves starting on your hands and knees, then extending one arm and the opposite leg while keeping your core engaged. This exercise helps improve balance and coordination.

I also found that the hollow body hold was a great way to target the deep core muscles. It involves lying on your back with your arms and legs extended, then lifting your head and shoulders off the ground while keeping your lower back pressed to the floor.
