The 5 Best Oblique Exercises for a Strong Core

The core of our body, often heralded as the powerhouse, plays a pivotal role in virtually every movement we make. Within this central hub, the oblique muscles are key players, often overshadowed by the more talked-about abs but equally important in ensuring a well-rounded strength and stability in our midsection. Strong obliques contribute significantly to overall core strength, which is not just about having a flat stomach or a six-pack. It’s about creating a solid foundation for both everyday activities and athletic endeavors.

These muscles, which run along the sides of the abdomen, are essential for movements involving twisting, bending, and side-to-side motions. Whether it’s performing daily tasks like turning to reach something behind you or engaging in sports that require rotational movements, strong obliques enhance your performance and reduce the risk of injury. In addition to their functional benefits, toned obliques also contribute to an aesthetically pleasing appearance, sculpting the waistline and contributing to a well-defined midsection. This dual role of obliques, both as a functional asset and an aesthetic enhancer, underscores their importance in a comprehensive fitness regimen.

In this article, we’ll explore five of the best exercises specifically targeting the oblique muscles, each designed to bolster your core’s strength and stability while also enhancing your body’s overall form and function.

Anatomy of the Obliques

The oblique muscles are a crucial component of the abdominal muscle group, playing a vital role in the human body’s core strength and stability. These muscles are located on the sides of the abdomen, stretching from the lower ribs to the pelvis. They are uniquely positioned, enabling them to facilitate a variety of movements and contribute to overall torso and spine stability.

There are two main types of oblique muscles: the internal obliques and the external obliques. The external obliques sit on the surface and are the more visible of the two, especially in well-trained individuals. They originate from the lower eight ribs and extend down to the pelvis, attaching to the iliac crest. These muscles are primarily responsible for rotating the trunk and bending it sideways. When you twist your torso or bend to tie a shoe, you’re engaging your external obliques.

Beneath the external obliques lie the internal obliques. These muscles are deeper and run perpendicular to the external obliques. They attach from the lower three ribs to the linea alba (a fibrous structure running down the abdomen) and to the pelvis. The internal obliques work alongside the external obliques to aid in rotating and bending the torso, but they also play a unique role in supporting the abdominal wall, assisting in respiration, and helping maintain proper posture.

The synergy between the internal and external obliques is crucial for a range of motions. They enable the torso to twist and bend in various directions, which is essential not just in athletic activities but also in everyday tasks. Moreover, strong obliques contribute significantly to maintaining good posture. They support the spine, helping to distribute weight evenly and reduce the strain on the back muscles. This is particularly important in preventing lower back pain, a common ailment in today’s sedentary lifestyle.

Understanding the anatomy and function of the oblique muscles is the first step in recognizing their importance in a balanced core workout and overall physical health.

The 5 Best Oblique Exercises

Exercise 1: Russian Twists

Russian Twists are a dynamic exercise that target the oblique muscles, enhancing core strength and rotational ability. Here’s how to perform them:

1. Starting Position: Sit on the floor with your knees bent and feet flat. Lean back slightly to create a V-shape with your torso and thighs. This is your starting position.
2. Movement: Lift your feet slightly off the ground for an added challenge, or keep them on the floor for more stability. Extend your arms straight out in front of you, clasping your hands together or holding a weight for added resistance.
3. Execution: Engage your core and twist your torso to the right, bringing your arms parallel to the floor. Keep your movements controlled. Twist back through the center and then to the left. This completes one repetition.
4. Breathing: Exhale as you twist to each side and inhale as you return to the center.

Benefits for the Obliques:

• Russian Twists intensely work the oblique muscles by requiring them to contract as you twist from side to side.
• This exercise also engages the entire core, including the rectus abdominis and lower back, providing a comprehensive core workout.
• It helps improve balance and stability by challenging your core muscles to stabilize your body throughout the movement.

Variations and Tips for Beginners:

• For Beginners: Start with your feet on the floor and focus on perfecting the twist with proper form. As you gain strength, you can add the challenge of lifting your feet.
• Add a Weight: Holding a dumbbell or a medicine ball can increase the intensity of the workout, but only add weight once you’re comfortable with the basic movement.
• Maintain Good Form: Keep your back straight and avoid rounding it. Move slowly and with control, focusing on using your obliques to power the movement.
• Modifications: If you experience back discomfort, try doing the exercise on an incline bench or with your back against a wall for support.

Incorporating Russian Twists into your routine can significantly enhance oblique strength and contribute to a stronger, more stable core. Remember to start slow, focus on form, and gradually increase the intensity as your strength improves.

Exercise 2: Side Planks

Side planks are a powerful isometric exercise that targets the obliques, while also engaging the entire core, shoulders, and hips. Here’s a step-by-step guide to performing a proper side plank:

1. Starting Position: Begin by lying on your side with your legs extended and feet stacked on top of each other. Prop your upper body up on your forearm, making sure your elbow is directly under your shoulder for proper alignment.
2. Lift and Hold: Engage your core and lift your hips off the ground, forming a straight line from your ankles to your shoulders. Keep your head in a neutral position, and avoid dropping your hips. Your weight should be supported on your forearm and the side of your foot.
3. Maintain Position: Hold this position, keeping your core muscles engaged. Ensure your hips don’t sag or lift too high. Your body should maintain a straight, diagonal line.
4. Duration: Aim to hold the side plank for 20-30 seconds to start, gradually increasing the duration as you get stronger.
5. Alternate Sides: After completing the hold on one side, switch to the other side and repeat.

How Side Planks Target the Obliques:

• The side plank primarily engages the oblique muscles on the side you’re lifting from. These muscles have to work hard to keep your torso stable and maintain the straight, diagonal line of your body.
• This exercise also recruits other core muscles for stability, making it an excellent workout for overall core strength.

Modifications for Different Fitness Levels:

• Beginners: Start with a modified side plank by bending your knees and stacking them on the floor. Lift your hips while keeping your knees on the ground.
• Intermediate: Perform the standard side plank as described, focusing on maintaining proper form and increasing hold time.
• Advanced: For a more challenging workout, try lifting the top leg, holding a weight in your top hand, or performing side plank dips by slightly lowering your hip and then lifting it back up.
• Extra Support: If you have shoulder or wrist issues, you can perform the exercise with your supporting arm fully extended, palm flat on the ground.

Remember, the key to effective side planks is maintaining proper form and alignment. Start with a duration and modification that suits your fitness level and gradually progress as your strength and stability improve.

Exercise 3: Bicycle Crunches

Bicycle crunches are a dynamic and efficient exercise for targeting the obliques, along with other core muscles. Here’s how to perform them effectively:

1. Starting Position: Lie flat on your back with your knees bent and feet flat on the ground. Place your hands behind your head without interlocking your fingers. Lift your shoulders slightly off the ground to start the crunch position.
2. Movement: Lift your feet off the ground and bring your knees towards your chest. Then, extend one leg out straight at a 45-degree angle from the ground while simultaneously twisting your upper body so the opposite elbow comes towards the bent knee.
3. Alternate Sides: Quickly switch to bring the other elbow towards the opposite knee as you simultaneously switch the position of your legs, mimicking a pedaling motion.
4. Breathing: Exhale as you twist and bring your elbow to your knee, and inhale as you switch sides.

Why They’re Excellent for Oblique Engagement:

• Bicycle crunches require a rotational movement that directly engages the oblique muscles.
• This exercise also targets the rectus abdominis and transverse abdominis, providing a comprehensive core workout.
• The alternating motion ensures that both the internal and external obliques are effectively worked on each side.

Common Mistakes to Avoid:

• Pulling on Your Neck: Avoid yanking your head with your hands. Keep your fingers lightly touching the sides of your head and focus on using your core to power the movement.
• Losing Form: It’s important to keep a controlled motion throughout the exercise. Avoid rushing the movements; slower, controlled motions are more effective than rapid, uncontrolled ones.
• Elbow to Knee Focus: Rather than trying to touch your elbow to your knee, focus on the twist in your torso. It’s the rotation that engages the obliques, not just the elbow-to-knee contact.
• Flat Back: Ensure your lower back remains in contact with the floor to avoid strain. If you find this difficult, reduce the range of motion until you build more strength.
• Breathing: Proper breathing is essential. Don’t hold your breath — breathe out as you twist and in as you return to the starting position.

Bicycle crunches can be a highly effective exercise for strengthening and toning the obliques. By avoiding common mistakes and focusing on controlled, deliberate movements, you can maximize the effectiveness of this exercise for your core workout.

Exercise 4: Windshield Wipers

Windshield Wipers are an advanced core exercise that primarily targets the oblique muscles. They also engage the entire core and lower back. Here’s how to perform them safely and effectively:

1. Starting Position: Lie flat on your back on a mat with your arms extended out to the sides for stability. Lift your legs and bend your knees at a 90-degree angle, so your thighs are perpendicular to the ground.
2. Movement: Engage your core muscles and slowly lower your legs to one side, keeping your knees together and bent at 90 degrees. Lower them as far as you can while keeping your shoulders flat on the ground.
3. Return and Alternate: Bring your legs back to the center and then lower them to the other side. Your movements should be controlled and steady, like a windshield wiper.
4. Breathing: Exhale as you lower your legs to each side and inhale as you bring them back to the center.

Impact on the Obliques and Core:

• Windshield Wipers intensely work the oblique muscles as they control the side-to-side leg movement.
• This exercise also engages the rectus abdominis and the deep core muscles, enhancing overall core strength and stability.

Tips for Adjusting Difficulty:

• For Beginners: Start with your feet closer to the ground and reduce the range of motion. You can also perform the exercise with bent knees to lessen the intensity.
• Intermediate Level: Perform the exercise with straight legs, increasing the lever length and thus the difficulty.
• Advanced Variation: For an added challenge, hold a light weight between your feet or perform the movement slower for increased time under tension.
• Extra Support: If you have lower back concerns, place a small rolled towel under your back for support and ensure not to lower your legs too far to either side.
• Control is Key: Always perform this exercise with control to prevent strain on your lower back. If you feel any back pain, stop immediately and adjust your form or reduce the range of motion.

Windshield Wipers are a challenging exercise that can significantly enhance the strength and endurance of your oblique muscles. By starting at an appropriate level and focusing on controlled, deliberate movements, you can effectively incorporate this exercise into your core strengthening routine.

Exercise 5: Oblique V-Ups

Oblique V-Ups are a targeted exercise that focuses on the oblique muscles, offering an intense workout for core strengthening. Here’s how to perform them:

1. Starting Position: Lie on your side with your legs extended and your body in a straight line. Place your lower arm on the ground for stability, and your upper hand behind your head or along your side for balance.
2. Movement: Engage your obliques to lift both your upper body and legs off the ground simultaneously, bringing your upper elbow towards your hip. Your body should form a “V” shape at the top of the movement.
3. Return to Start: Slowly lower back down to the starting position without letting your legs or shoulders completely rest on the floor between repetitions.
4. Alternate Sides: After completing a set on one side, switch to the other side and repeat.

Benefits for Targeted Oblique Strengthening:

• Oblique V-Ups directly engage and isolate the oblique muscles, leading to increased strength and definition in this area.
• They also involve the core stabilizers, aiding in overall core strength and improved balance.
• This exercise enhances functional fitness, aiding movements that involve bending and twisting.

Modifications for Various Skill Levels:

• Beginners: Start by performing the exercise with a smaller range of motion. You can also bend your knees slightly to reduce the intensity.
• Intermediate Level: Perform the exercise as described, focusing on form and ensuring that the movement is driven by your obliques.
• Advanced Variation: To increase the difficulty, hold a light dumbbell or medicine ball in your upper hand. You can also increase the number of repetitions or slow down the movement for a greater challenge.
• Extra Support: If you find the exercise too challenging or experience any discomfort, you can keep the lower leg on the ground and only lift the upper leg and torso.

It’s important to keep the movements controlled and avoid using momentum to lift your body. The effectiveness of Oblique V-Ups comes from deliberate, focused engagement of the obliques throughout the exercise. As you build strength, you can gradually increase the intensity and complexity of the exercise to continue challenging your muscles.

Incorporating Oblique Exercises into Your Routine

Incorporating oblique exercises into your fitness regimen is essential for a balanced core workout and overall strength. Here are some tips on how to effectively do this:
