The rectus abdominis, or “six-pack” muscles, likely get all the love in your core workout. Do you know what doesn’t get a lot of love? If you guessed the obliques, collect $200 as you pass GO. The obliques need some attention, too.

This is about to change with the exercises below that you can use to create oblique workouts. 

The obliques, which run beside the abs, are important core muscles that are often forgotten about when people are focused on building a ripped and muscular core. But after you read about the oblique exercises below, you’ll be ready to strengthen them in your abs workout, right?

Then let’s get to it. 

Oblique Muscles and Functions Explained

The obliques are actually two muscles: the internal and external obliques. They run beside your rectus abdominis muscles from the hips to the rib cage. The external oblique starts from the external surfaces of ribs five through 12 and inserts around the pelvis.

The internal obliques run under the external obliques, and their muscle fibers travel perpendicular to each other. Internal obliques originate from the Iliac crest (pelvis) and the lower back fascia and insert on ribs 10 through 12. The oblique muscles’ five primary functions are:

  • Spinal Flexion
  • Lateral flexion/Anti-Lateral Flexion
  • Rotation/Anti-Rotation  

But the oblique muscles really make money by protecting your lower back from rotation, known as anti-rotation. This is why the oblique muscles are commonly called anti-rotation muscles. 

Oblique Strengthening Benefits

When you focus on your obliques, you can expect the following benefits. 

Reduced Lower Back Pain

Since the obliques are attached to the spine, their strength can help take the pressure off your vertebrae, discs, and other core muscles to reduce your chances of suffering from a sore lower back.

Better Posture

Almost all abdominal muscles in and around the spine play a role in posture, and the obliques are no different. If the obliques are weak and fail to support your spine, other muscles pick up the slack, affecting good posture.  

Improved Balance

If you wobble from side to side when you walk, bend over, or stand, weak obliques may be the reason. Because lateral flexion is an essential oblique function, so is anti-lateral flexion. The stronger your obliques are, the steadier you are when standing and moving, improving your balance. 

Best Oblique Exercises

Your oblique muscles will be neglected no more with the following core exercises that focus on your overlooked obliques to really help you build a strong core. 

Side Plank with Arm Reach

Why it’s great: The side plank strengthens your obliques and shoulder stabilizers. Adding movement with the arm reach makes your obliques work harder, too. 

How to do it:

  1. Lie on your left side with your weight resting on your elbow. Your left elbow should be directly underneath your left shoulder and your legs stacked on each other.
  2. Engage your glutes, lift your hips, and push your left elbow into the ground to push yourself up into the side plank position, keeping a neutral spine.
  3. Raise your right arm over your head, then bring it down and reach under your body before you return to the starting position. Try to keep your hips stacked and avoid twisting too much.
  4. Reset and repeat for desired reps or for time.

Heel Taps

Why it’s excellent: Heel taps are an easy exercise to learn, are spine friendly, and directly target the obliques.  

How to do it:

  1. Lie on your back with your knees bent, feet flat on the ground, and arms down by your sides.
  2. Perform a slight crunch and bend to the side slightly to reach your right hand to touch your right ankle. 
  3. Return to the starting position and repeat with the left side.
  4. That is one rep. Keep alternating sides for desired repetitions.

Cross-Body Mountain Climber

 

Why it’s great: The cross-body mountain climber is an exercise that targets the entire core area, and when done with speed, this exercise is great cardio, too. The cross-body part engages the obliques, hip flexors, rectus abdominis, and upper body strength with the chest, shoulders, and triceps.

How to do it:

  1. Set up in the push-up plank position, with your hands underneath your shoulders, and engage your glutes to keep your body straight. 
  2. Drive your right knee toward your left elbow while maintaining the plank position.
  3. Return your right foot to the ground and repeat with the left knee to the right elbow.
  4. Keep alternating sides for even reps or for time.

Bicycle Crunches

Why it’s great: Bicycle crunches are a great all-around ab exercise because they strengthen the upper and lower abs and require good coordination to perform well. 

How to do it:

  1. Lie face up on the ground with both legs extended and your toes pointed at the ceiling.
  2. Place both hands behind your ears and lightly grip the back of your head.
  3. Twist to your right side, bringing your right elbow and your left knee toward each other simultaneously. Return to the starting position.
  4. Twist to your left, bringing your left elbow toward your flexed right leg, then return to the starting position.
  5. Alternate side for an even number of repetitions. Your legs should look like they are riding a bike.

Dumbbell Suitcase Carry

Why it’s great: The dumbbell suitcase carry strengthens the obliques due to anti-lateral flexion and strengthens grip imbalances between sides. It also works the shoulders and glutes, making an excellent full-body exercise. 

RELATED: Best Dumbbells

How to do it:

  1. Grip a dumbbell weighing 25-50% of your body weight in your left hand.
  2. Ensure your shoulders are even and your chest is up.

How to do it:

  1. Lie face up on the floor and bring your outstretched arms to shoulder level.
  2. Raise your legs vertically with your feet together and ensure your lower back is on the ground.

Plank Hip Dips

Why it’s great: Because you’re in the front plank position while performing hip dips, you are strengthening your entire core region while focusing on your obliques. 

How to do it:

  1. Assume an elbow front plank position with your elbows underneath your shoulders, glutes engaged, and spine neutral.
  2. Rotate your hips to the left and lightly touch the ground.
  3. Then go back to the start and rotate your hips to the right.
  4. Keep alternating sides for even reps.

Woodchoppers

Why it’s great: No matter the variation of the woodchopper you do, it improves core strength and strengthens the hips and upper body dynamically at the same time. 

How to do it:

Note: This is one variation only. There are multiple ones.

  1. Hold a light medicine ball or dumbbell in both hands at the side of your right hip.
  2. Then raise the ball/dumbbell across your body and over your left shoulder, like throwing a bucket of water over your shoulder. 
  3. Bring it down across your body back to your right hip and repeat. 
  4. Then switch to the opposite side and repeat for even repetitions.

Russian Twists

Why it’s great: Russian twists, when performed with proper form, strengthen the obliques, hip flexors, and lower back and improve your balance and stability.  

How to do it:

  2. Sit upright with your shoulders down and chest up, lean back slightly, and lift your feet off the ground. 
  3. Rotate to the right and touch the med ball to the ground, then rotate to the left and do the same. 
  4. Alternate side for even repetitions.

How to do it:

Note: You’re going to need a wall to throw against.

  1. Stand 2-4 feet away from a wall with your left side facing it, holding a med ball in both hands. 
  2. Transfer your weight to your left hip while rotating your torso and throwing the ball against the wall. Remember, power comes from the hip rotation and not the arms. 
  3. Catch the ball with both hands and reset and repeat.
  4. Repeat for an equal number of reps on the right side.

FAQs: Oblique Workouts

What is the best exercise to sculpt your obliques?

If only one best exercise for each body part existed, wouldn’t that be nice? But unfortunately, this is not the case. Because the obliques have five primary functions, it helps to train them a few different ways, like anti-lateral flexion (side planks), dynamic (bike crunch), and powerfully (med ball side toss).

Do oblique workouts slim your waist?

If you have more body fat than allows you to see your obliques, strengthening them can potentially help give your waist a more sleek appearance by giving you more definition. You need to exercise in combination with a calorie-controlled diet to see any significant change in your body composition, however.

How do you build your obliques?

Obliques are only visible when you have low body fat and enough muscle mass. If you want to build your obliques, you do it as you would with any other exercise—add resistance and progressively overload them to get them bigger and stronger.

Do obliques thicken your waist?

When you build and strengthen the oblique muscles, your waist can get wider, sometimes giving your torso a more “boxy” look—but you have to add quite a bit of muscle mass for that to happen.
