Oblique Workout: Best Exercises for Side Abs

Understand what your obliques do

If you want a stronger core and more defined side abs, an oblique workout should be part of your routine, not an afterthought. Your oblique muscles run diagonally along the sides of your torso and come in two layers: the external obliques and the internal obliques. Together they help you twist, bend sideways, and stabilize your spine during almost every movement you make.

According to a 2022 article in Dynamic Chiropractic, focusing only on the superficial “six pack” muscle, the rectus abdominis, is not enough for true core strength. Neglecting your obliques can weaken spinal stability and raise your risk of lower back and even shoulder injuries. Your oblique workout is what ties your whole trunk together.

Why your side abs matter

Your obliques help you:

• Rotate and bend your torso
• Maintain healthy posture and spinal alignment
• Brace and stabilize your core during lifts like squats and deadlifts
• Control everyday motions like reaching, throwing, or lifting groceries
• Reduce strain on your lower back, neck, and shoulders

A 2025 Peloton blog post explains that the obliques are crucial for stabilizing, twisting, and bending in both daily life and athletic activities, and that stronger obliques can reduce the risk of lower back pain by promoting better alignment and resisting unwanted spinal movement.

In other words, training your obliques is about much more than carving out side abs. It is about building a core that supports everything you do.

Know the benefits of oblique training

Before you jump into exercises, it helps to know what you are working toward. A consistent oblique workout can change how your body feels and moves day to day.

Improve posture and reduce back pain

Your internal and external obliques support your spine from the sides. When they are strong, they:

• Help keep your ribs stacked over your hips
• Prevent excessive arching or rounding through your lower back
• Share the load with your lower back muscles so they do not do all the work

Research summarized in the Peloton article notes that targeted oblique training improves posture and can ease lower back discomfort by supporting proper spinal alignment and balancing muscle workload across your torso.

Build better balance and stability

Whenever you stand on one leg, change direction, or move something heavy to one side, your obliques are working hard behind the scenes.

Strengthening them helps you:

• Stay stable when you walk on uneven ground
• Land more safely from jumps
• Cut or pivot more confidently in sports
• Resist being pulled or tipped off balance

Your obliques also play a big role in “anti rotation,” which means keeping your torso steady when a force tries to twist you. Exercises that challenge this function, like suitcase carries and Pallof presses, are especially useful for overall stability, according to a 2024 Men’s Health fitness article.

Support performance and everyday strength

A strong oblique workout routine can boost:

• Rotational power for sports like tennis, golf, baseball, and pickleball
• Bracing strength for heavy lifts such as squats and deadlifts
• Functional strength for everyday tasks like shoveling, pushing, and pulling

Oblique training contributes to both top down and bottom up movements. That means it helps you generate power when your upper body moves over a stable lower body, and when your lower body drives movement under a more fixed upper body.

Shape and define your waist

You cannot target fat loss in one spot, but you can strengthen and build the muscles under the skin. Consistent oblique training combined with a healthy diet and regular cardio can help reduce the appearance of “love handles” by tightening and toning the area.

Contrary to a common myth, oblique workouts do not automatically “widen” your waist or create a boxy look. They tend to define and sculpt your side abs instead, especially when you mix strength work with overall body composition changes.

Learn the main oblique movement patterns

To build a balanced oblique workout, you want to train how these muscles actually work. Most effective routines include a mix of:

• Lateral flexion: Bending your torso to the side
• Rotation: Twisting your torso
• Anti rotation: Resisting a twist
• Anti lateral flexion: Resisting a side bend
• Flexion with rotation: Bending forward with a twist, used carefully to avoid strain

A 2024 Men’s Health piece notes that effective oblique training goes beyond simple side bends. It should challenge your muscles with instability, uneven loads, and resisted rotation so you build strength and control, not just repetition.

Try this beginner friendly oblique workout

You can start with a short routine that fits easily into your week. Aim to do this oblique workout 3 or 4 times per week, either at the end of your cardio or strength training.

Perform 2 to 3 rounds, resting 30 to 60 seconds between exercises.

1. Side plank

• Lie on your side with your elbow under your shoulder and legs stacked.

• Lift your hips so your body forms a straight line from head to feet.

• Keep your core braced and avoid letting your hips sag.

• Hold for 20 to 30 seconds per side.

  Why it works: Side planks train anti lateral flexion and build deep oblique and core stability, which supports your spine and posture.

1. Russian twists

• Sit on the floor with your knees bent and heels down.

• Lean back slightly with a straight spine and brace your core.

• Clasp your hands or hold a light weight.

• Twist your torso to one side, then to the other, moving with control.

• Do 16 to 20 total twists.

  The Peloton blog highlights Russian twists as one of several effective oblique exercises that blend forward bending and rotation to target both internal and external obliques.

1. Bicycle crunches

• Lie on your back with hands lightly behind your head, elbows wide.

• Lift your shoulders and bring one knee toward your chest.

• Rotate your torso so your opposite elbow moves toward that knee.

• Switch sides in a pedaling motion, moving slowly and with control.

• Do 16 to 20 total reps.

  Why it works: Bicycle crunches train rotation and flexion together, hitting the rectus abdominis and obliques while also challenging coordination.

1. Heel taps

• Lie on your back with knees bent, feet flat and wider than hip width.

• Lift your shoulders slightly off the floor, bracing your core.

• Reach your right hand toward your right heel, then your left hand toward your left heel.

• Keep the movement small and controlled.

• Do 20 total taps.

  Why it works: Heel taps emphasize side bending in a small range of motion, helping you feel your side abs switch on without straining your neck or back.

If any movement feels too intense, shorten the range of motion or reduce the reps. Your goal is smooth, controlled work, not rushing through the set.

Build an intermediate oblique workout

Once you feel comfortable with the basics, you can add more dynamic moves and anti rotation work to your oblique workout.

Try this routine 2 or 3 times per week, with 2 or 3 rounds:

1. Side plank with hip dips

• Start in a strong side plank.
• Lower your hips toward the floor with control, then lift them back up.
• Keep your body in one straight line, moving from the ribs rather than the shoulders.
• Do 10 to 12 dips per side.

1. Mountain climbers

• Begin in a high plank position with hands under shoulders.
• Brace your core and keep your body in a straight line.
• Drive one knee toward your chest, then switch, as if you are running in place.
• To emphasize your obliques, angle each knee slightly toward the opposite elbow.
• Go for 20 to 30 seconds.

1. Woodchops with a weight or band

• Stand with feet shoulder width apart holding a dumbbell, medicine ball, or cable handle.

• Start with the weight up by one shoulder.

• Shift your hips and rotate your torso as you “chop” the weight diagonally down across your body toward the opposite hip.

• Reverse to return to the start.

• Do 10 to 12 reps per side.

  Peloton’s 2025 article identifies woodchops as a key oblique move because they combine forward bending, side bending, and rotational forces in one exercise.

1. Suitcase carry (single arm carry)

• Hold a dumbbell or kettlebell in one hand by your side.

• Stand tall with shoulders level and ribs stacked over hips.

• Walk 20 to 40 steps without letting the weight pull you to the side.

• Switch hands and repeat.

  The 2024 Men’s Health article points to single arm loaded carries like the suitcase carry as powerful anti lateral flexion exercises that teach your obliques to keep you upright against uneven loads.

1. Pallof press (with band or cable)

• Attach a resistance band or cable at chest height.

• Stand sideways to the anchor point and hold the handle at your chest with both hands.

• Step away until there is tension on the band.

• Press your hands straight out from your chest, then slowly bring them back.

• Do 10 to 12 reps per side, resisting the pull that tries to twist you.

  This is a classic anti rotation drill that directly trains your obliques to control unwanted twisting.

Explore advanced oblique exercises

When you are ready for more challenge and you have solid technique, you can test your strength and control with advanced oblique moves mentioned in the 2024 Men’s Health and 2025 Peloton resources.

Use these sparingly at first and focus on form rather than load or speed.

Kettlebell windmill

• Stand with feet slightly wider than hip width, toes turned out a bit.
• Press a kettlebell overhead with one arm, keeping your shoulder packed.
• Shift your hips away from the weight as you hinge and slide your opposite hand down your leg toward the floor.
• Keep your eyes on the kettlebell and your torso as long as possible.
• Use your obliques and glutes to return to standing.

This movement hits your obliques, glutes, and shoulders while demanding excellent stability and body awareness.

Hanging oblique knee raises

• Hang from a pull up bar with a strong grip.
• Brace your core and keep your shoulders away from your ears.
• Bring your knees up toward one side of your torso using your abs, not swinging.
• Lower with control and repeat to the other side.

The Peloton blog lists hanging oblique knee raises among the top oblique exercises because they challenge bottom up rotation and core control at the same time.

Plank rotations

• Start in a high plank with hands under shoulders.
• Shift your weight to one hand and rotate your body, opening into a side plank while reaching the free arm toward the ceiling.
• Return to plank and rotate to the other side.

This flow keeps your obliques under tension while moving through rotation and anti rotation.

Ab wheel rollout (with oblique focus)

• Begin on your knees holding an ab wheel.
• Roll the wheel forward in a straight line, stopping before your lower back sags.
• To emphasize one side, roll out slightly diagonally, then return.
• Alternate directions.

The Men’s Health article identifies the ab wheel rollout as an advanced core move that works the obliques through anti extension and anti rotation, provided you control the range.

Use oblique crunches the right way

Oblique crunches are a classic for side abs, but they are easy to rush or perform with poor technique.

How to do a basic oblique crunch

• Lie on your back with knees bent and feet flat.
• Place your fingertips lightly behind your head, elbows wide.
• Lift your shoulders slightly off the floor by bracing your core.
• Rotate your torso as you crunch, bringing one shoulder toward the opposite knee.
• Lower with control and repeat on the same side or alternate.

During this movement, the main muscles working are the internal and external obliques, the rectus abdominis, and the transverse abdominis which stabilizes your torso.

Helpful variations

You can adjust difficulty with:

• Side lying oblique crunch: Lie on one side with knees bent and crunch your ribs toward your hip.
• Weighted oblique crunch: Hold a plate or dumbbell across your chest to increase load.
• Raised leg oblique crunch: Lift bent knees over your hips to decrease hip flexor help and increase core demand.

Mistakes to avoid

To make oblique crunches safe and effective:

• Avoid yanking on your neck. Keep fingertips light and elbows wide.
• Keep your lower back close to the floor so you do not overuse your hip flexors.
• Move slowly and pause briefly at the top of each rep to really engage your muscles.

Racing through reps with momentum often just tires your neck and hip flexors without challenging your obliques much.

Rethink traditional side bends

Dumbbell side bends are a common oblique exercise, but they are not always your best option.

Research notes that:

• Using two dumbbells at the same time causes the weights to counter each other, which reduces the challenge to your obliques.
• Going too low into a side bend can push your spine into an unsafe range of motion without offering extra benefit.

If you like side bending work, you might get more from cable side bends.

Why cable side bends can be better

Cable side bends allow you to:

• Control the load through the entire range of motion
• Stay within an active, comfortable range for your spine
• Train pure lateral flexion without combining it with rotation, which can decrease injury risk
• Engage your hip abductors as stabilizers, which adds extra hip and glute strengthening

You can also adjust the height of the cable to change where the movement is hardest. A low cable challenges you more at the bottom of the bend, while a high cable emphasizes the effort near the top when you are closer to standing upright.

Follow form tips for safer oblique workouts

Good technique is what makes your oblique workout effective rather than irritating to your lower back or neck. The Peloton article and other sources highlight several form cues you can use.

Brace your core properly

Think of bracing as gently tightening your midsection as if preparing for a light poke. You should feel your ribs and hips draw slightly toward each other without holding your breath.

• Keep your ribs stacked over your pelvis.
• Avoid flaring your ribs forward or arching your lower back.
• Imagine a wide belt around your torso that you are pushing out against slightly.

Match your breathing to effort

Controlled breathing keeps your core engaged and improves endurance:

• Inhale during the easier part of the movement.
• Exhale during the effort, such as when you twist, lift, or press.

Combining oblique work with mindful breathing can even support better respiratory function, since the diaphragm and abdominal muscles assist with breathing and pressure control.

Protect your lower back and neck

Simple alignment checks go a long way:

• Keep your neck in line with your spine, not craned forward.
• Avoid arching your lower back during planks, mountain climbers, or ab wheel rollouts.
• Use pelvic tucks when needed, gently rolling your hips under to keep your core and glutes engaged and your lower back supported.

If you feel strain in your lower back or neck instead of your side abs, ease off the range of motion or choose a simpler variation.

Fit oblique workouts into your week

You do not need long, complicated sessions to see benefits. Several sources note that even 5 to 10 minutes of focused oblique training, 3 to 4 times per week, can help you build rotational power, improve posture and alignment, and reduce back strain.

Here are a few simple ways to structure that time:

• Quick finisher: Add 3 to 4 oblique moves at the end of a full body workout.
• Core circuit day: Dedicate one short session just to core, alternating oblique work with front of core and back of core exercises.
• Movement snacks: Do one oblique exercise in the morning and another in the evening on a few days each week.

Aim for a mix of:

• One side plank or anti lateral flexion exercise
• One rotational or anti rotation move
• One dynamic drill like woodchops, mountain climbers, or bicycle crunches

Then adjust the exercises and sets as you get stronger or your schedule changes.

Key takeaways for your side abs

• Your oblique muscles are essential for twisting, bending, posture, and spinal stability, not just for visible side abs.
• A smart oblique workout includes rotation, anti rotation, side bending, and stability exercises.
• Consistent training can improve balance, reduce back pain, support lifts and sports, and help define your waist.
• Start with basics like side planks, Russian twists, and heel taps, then progress to moves like woodchops, suitcase carries, and Pallof presses.
• Focus on form, breathing, and controlled movement, and keep your lower back and neck supported.

You do not have to overhaul your entire routine to benefit from oblique training. Start by adding one or two of these exercises to your next workout, notice how they feel, and build from there as your side abs get stronger.
