Dumbbell Core Exercises for a Leaner, Stronger, and Defined Torso

Sculpting your chest:

Your gym buddy says he wants to do some “core” exercises. What comes to mind? If you exclusively think about your stomach, you’re not alone. But here’s the thing: Your core is made up of more than your stomach. Sure, your stomach is a part of your core, but it’s not the core. Are you starting to get it? If your goal is to flatten that stomach and start to see some definition, or if you want a full-on six-pack, that’s a good start. But we want you to look beyond your stomach.

Strengthening your entire core will help you get that flat stomach, but you’ll also see improvements in proper movement patterns while you lower your risk of injury. And to do that, we want you to use one of the best weightlifting equipment: the dumbbell. Let’s look at the best dumbbell core exercises, and we’ll also make sure you have some dumbbell core workouts to get you started.


Before we discuss the best dumbbell core exercises, it’ll be important to break down all the muscles that make up your core. (Remember that it’s more than your stomach). Understanding the core musculature will strengthen your mind-to-muscle connection. That can translate into better performance, which means better results.

Rectus Abdominis: Everyone knows the rectus abdominis. In fact, this muscle alone makes up the core. The rectus abdominis is commonly called your abdominal muscles or your abs. This muscle is front and center, starting at your solar plexus and running down to your groin.

Transverse Abdominis: Sitting beneath the rectus abdominis, you’ll find a layer of deep muscle tissue known as the transverse abdominis. Despite playing a key role in rotational movements and abdominal contractions, it doesn’t get as much time in the spotlight as the rectus abdominis (although we think it definitely should). Learning to activate and control this muscle can make an insane difference in your results.

External Obliques: Put your hands on your ribs. These are your external obliques. Sitting on the sides of your torso, your obliques are responsible for assisting with rotational movements. They are just as important for anti-rotational movements or fighting against the pull toward a certain direction. A great example of this is when you perform a one-handed standing cable fly.

Internal Obliques: Just like with the rectus abdominis and the transverse abdominis, the external obliques are the ones that hog the attention. Meanwhile, underneath the external obliques, you’ll find the internal obliques. Like their external counterpart, the internal obliques take care of basic twisting and turning movement patterns and anti-rotational movements.

Erector Spinae: Finally, we have the erector spinae. These muscles are located in your back, and they run up the spine. They complete the core, providing balance and stability to rotational movements.

Okay, could you pass an anatomy course now?

Here’s some homework: Pop the shirt up and look in the mirror. Study your entire core and practice flexing each muscle group we covered. When you strengthen your mind-to-muscle connection, you can improve your overall performance. And as we mentioned above, the better your performance, the more you activate the target muscles, the better results you can get.


Below is a list of the most effective dumbbell core exercises. To make building your own core workouts easier, we’ve separated the dumbbell exercises for a flat stomach according to the muscles they target. Below this, we’ll discuss how to combine all these moving parts to build your core workout.

Rectus Abdominis

Transverse Abdominis 


Erector Spinae


Here are some tips for building your own ab workouts based on the exercises we’ve listed above.

Pick Your Exercises

This will depend on how often you want to target your core each week. We recommend having a standalone “Core Day” or incorporating exercises into existing workouts thrice a week. Base the exercises you choose on the exercises you’re already doing that day. For example, if you’re focusing on your legs, you’re probably doing hamstrings, so you can easily throw in dumbbell deadlifts. Break this down so you do one or two core exercises within a few of your current workouts. Try to stagger different muscles of the core on different days. The other option is to dedicate an entire day or most of a workout to your core. Then you can perform one to three exercises for each part of your core.

Sets and Repetitions

This depends on how much weight you’re using. In general, if you use more weight, then you’ll perform fewer repetitions with more sets. The less weight you use, the more repetitions and the fewer the sets. Heavier weights are better for building the core musculature. Lighter weights are better for definition.

Choose Your Rest Time

If you want to burn more calories and keep your heart rate up, you’ll want to shorten your rest breaks but not so much that it negatively impacts your posture and form. Resting for 60 seconds is standard. But if you’re using heavier weights, consider resting between 90 and 120 seconds.

Pick Your Methodology

If you have a good deal of weightlifting experience, we recommend switching up the methodology of your workouts. For example, you can superset one of your current exercises with a core exercise, such as Romanian deadlifts with a dumbbell sit-up.

Even though you have the know-how to make your dumbbell core workouts, we want to help you get started. Below, you’ll find three different dumbbell ab workouts you can use today. As we said above, each workout can be done as a standalone or split between two upper-body workouts.

Beginner Dumbbell Ab Workout

This is a basic, no-frills core workout. We want you to focus on performing the exercise perfectly for each repetition. These movements will help you build a foundation that will help you get stronger and take on more advanced abdominal and core exercises. Perform all of the repetitions for each set. Give yourself between 90 to 120 seconds of rest with each set.

  • Lying Dumbbell Crunch: 3 sets of 10 to 15 repetitions
  • Dumbbell Reverse Crunch: 2 x 10 – 15
  • Dumbbell Bird Dog: 2 x 10 – 15
  • Dumbbell Side Bend: 2 x 10 – 15
  • Dumbbell Superman: 2 x 8 – 15

Intermediate Dumbbell Core Workout

Same idea as the beginner workout, except we’re using more challenging exercises and shortening your rest break. Try to only rest for 60 seconds between sets.

  • Lying Leg Raise: 3 sets of 10 to 15 repetitions
  • Dumbbell Bird Dog: 2 x 10 – 15
  • Vacuum: 2 x 10 – 15 seconds
  • Dumbbell Side Plank: 2 x 8 – 15
  • Russian Twists: 2 x 10 – 15
  • Dumbbell Back Extensions: 2 x 8 – 15
  • Dumbbell Suitcase Carry: 2 x 20 – 25 seconds

Advanced Dumbbell Ab Workout

We want you to use the super-setting methodology in this advanced core workout. This is when you perform one core exercise and immediately perform the next exercise with no break. It’s a high-intensity way to lift, so if you get burned out, give yourself a longer break. We would rather have you rest longer than make a mistake and get injured because you’re too tired.

We’ve paired the exercises you’ll perform one after another and assigned them the same letter. But here’s an important catch: You’ll perform a heavy movement followed by a light movement. You can tell by the number of reps you’re assigned. Remember, fewer reps mean heavier weight; more reps mean lighter weight.

  • A: Dumbbell Deadlifts: 3 sets of 8 to 15 repetitions
  • A: Woodchopper: 3 sets of 20 repetitions

  • B: BOSU Dumbbell Sit-Ups: 2 x 8 – 12
  • B: Reach and Tuck: 2 x 15

  • C: Dumbbell Side Plank Rotations: 2 x 8 – 15
  • C: Dumbbell V-Up: 2 x 8 – 15


We’re big fans of dumbbells, especially when it comes to building a strong and defined core. If you don’t have any dumbbells, that’s okay. Many of the exercises listed above can be performed without a dumbbell. When you get a chance, be sure to throw a dumbbell into the mix to make it more challenging.

In conclusion, understanding the complexity of your core muscles and incorporating a variety of dumbbell core exercises can greatly benefit your fitness journey. Strengthening your entire core, including the rectus abdominis, transverse abdominis, obliques, and erector spinae, not only helps you achieve a flat stomach and defined abs but also improves overall movement patterns and reduces the risk of injury.

By following the suggested dumbbell core exercises and workouts, you can develop a strong mind-to-muscle connection and optimize your performance in the gym. Whether you're a beginner, intermediate, or advanced fitness enthusiast, these exercises cater to different levels and goals.

Remember, consistency is key to achieving lasting results. Make sure to choose the right exercises, sets, and repetitions based on your fitness level and customize your workouts accordingly. Always focus on maintaining proper form and technique to get the most out of each exercise.
