A strong, shredded six-pack is a common goal for many fitness enthusiasts, and bodyweight exercises are one of the most effective ways to achieve this. Not only do these exercises target the abdominal muscles, but they also engage other core muscles, enhancing overall strength and stability. Unlike machines or weights, bodyweight exercises can be performed anywhere, making them accessible and convenient.
This article delves into the 10 best bodyweight exercises for abs, backed by science, to help you carve out that six-pack. We will explore how each exercise works, the muscles it targets, and how it contributes to overall core strength.
The Science Behind Abs Training
Before we dive into the exercises, it’s essential to understand the anatomy and function of the abdominal muscles. The primary muscles that make up the “abs” include:
- Rectus Abdominis: This is the muscle most commonly associated with a six-pack. It runs vertically along the front of your abdomen and is responsible for flexing the spine and bringing the ribcage closer to the pelvis.
- Transverse Abdominis: This is the deepest layer of abdominal muscles, wrapping around your spine for stability and protection. It’s crucial for maintaining a flat stomach and good posture.
- Internal and External Obliques: These muscles run diagonally along the sides of the abdomen. They are responsible for rotating the torso and bending it sideways.
Effective abs training should target all these muscles to create a balanced and functional core. Research suggests that core stability is essential for overall athletic performance and injury prevention (Kibler, Press, and Sciascia, 2006). Furthermore, studies have shown that bodyweight exercises can effectively activate the abdominal muscles, often more so than traditional machine-based exercises (Schoenfeld and Contreras, 2011).
Top 10 Bodyweight Abs Exercises
1. Plank
How it Works:
The plank is a fundamental exercise that targets the entire core, particularly the transverse abdominis, by requiring you to hold a static position.
Muscles Targeted:
- Transverse Abdominis
- Rectus Abdominis
- Internal and External Obliques
- Glutes
Execution:
- Start in a forearm plank position with elbows directly under your shoulders.
- Keep your body in a straight line from head to heels, engaging your core and glutes.
- Hold this position without allowing your hips to sag or rise.
Why it’s Effective:
The plank is a highly effective isometric exercise, meaning it involves static muscle contractions, which enhances core stability (Ekstrom, Donatelli, and Carp, 2007). A study published in the Journal of Strength and Conditioning Research found that the plank and its variations are highly effective in engaging the core muscles, particularly when proper form is maintained (Escamilla et al., 2016).
2. Bicycle Crunch
How it Works:
The bicycle crunch is a dynamic movement that targets the rectus abdominis and the obliques by combining trunk rotation and flexion.
Muscles Targeted:
- Rectus Abdominis
- Internal and External Obliques
Execution:
- Lie flat on your back with your hands behind your head.
- Bring your knees up to a 90-degree angle.
- Alternate bringing your opposite elbow to the opposite knee while straightening the other leg.
Why it’s Effective:
The bicycle crunch has been shown to be one of the most effective exercises for activating the rectus abdominis and obliques. A study conducted by the American Council on Exercise (ACE) ranked the bicycle crunch as the top exercise for activating the rectus abdominis (Porcari et al., 2001).
3. Leg Raises
How it Works:
Leg raises primarily target the lower part of the rectus abdominis, which is often more challenging to engage than the upper portion.
Muscles Targeted:
- Rectus Abdominis
- Hip Flexors
Execution:
- Lie flat on your back with your hands by your sides or under your lower back for support.
- Keeping your legs straight, lift them towards the ceiling until your hips are at a 90-degree angle.
- Slowly lower your legs back down without touching the ground.
Why it’s Effective:
Leg raises are effective in targeting the lower abs, which are crucial for creating a balanced six-pack. Research indicates that exercises like leg raises, which involve lifting the legs rather than the torso, are more effective in engaging the lower rectus abdominis (Sarti et al., 1996).
4. Mountain Climbers
How it Works:
Mountain climbers are a dynamic, full-body exercise that also provides significant core engagement, particularly for the rectus abdominis and obliques.
Muscles Targeted:
- Rectus Abdominis
- Obliques
- Hip Flexors
Execution:
- Start in a high plank position with your hands directly under your shoulders.
- Drive one knee towards your chest, then quickly switch legs.
- Continue alternating legs at a fast pace.
Why it’s Effective:
Mountain climbers offer both cardiovascular benefits and core strengthening. The rapid movement requires constant engagement of the core muscles, providing both stability and power. Studies suggest that exercises that incorporate both static and dynamic muscle contractions, like mountain climbers, are beneficial for overall core development (McGill, 2010).
5. V-Ups
How it Works:
V-Ups are an advanced exercise that targets the entire rectus abdominis by requiring you to lift both the upper and lower body simultaneously.
Muscles Targeted:
- Rectus Abdominis
- Hip Flexors
Execution:
- Lie flat on your back with your arms extended overhead.
- Simultaneously lift your legs and torso to meet in the middle, forming a “V” shape.
- Lower back down with control.
Why it’s Effective:
V-Ups are highly effective for engaging the entire abdominal region, offering a comprehensive challenge to the rectus abdominis. A study published in the Journal of Sports Science & Medicine highlighted that exercises like V-Ups, which involve simultaneous flexion of both the upper and lower body, maximize abdominal muscle activation (Mendez-Villanueva et al., 2010).
6. Russian Twists
How it Works:
Russian Twists specifically target the obliques through a rotational movement, which is crucial for developing a well-rounded core.
Muscles Targeted:
- Internal and External Obliques
- Rectus Abdominis
Execution:
- Sit on the ground with your knees bent and feet slightly elevated.
- Lean back slightly, keeping your back straight.
- Hold your hands together and twist your torso to one side, then the other, touching the ground on each side.
Why it’s Effective:
Russian Twists are excellent for enhancing rotational strength and stability, which are essential for athletic performance. Research shows that rotational exercises like Russian Twists are effective in strengthening the obliques and improving overall core function (Willardson, 2007).
7. Hollow Body Hold
How it Works:
The Hollow Body Hold is an isometric exercise that targets the deep core muscles, including the transverse abdominis.
Muscles Targeted:
- Transverse Abdominis
- Rectus Abdominis
- Hip Flexors
Execution:
- Lie on your back with your arms extended overhead and legs straight.
- Lift your arms, shoulders, and legs off the ground, creating a hollow shape with your body.
- Hold this position, keeping your lower back pressed into the floor.
Why it’s Effective:
The Hollow Body Hold is crucial for building core endurance and strength, particularly in the transverse abdominis. A study in the Journal of Biomechanics found that exercises involving static holds, like the Hollow Body Hold, are highly effective in activating the deep core muscles and improving spinal stability (Hodges and Richardson, 1996).
8. Flutter Kicks
How it Works:
Flutter Kicks are a dynamic exercise that targets the lower abs and hip flexors through small, controlled leg movements.
Muscles Targeted:
- Rectus Abdominis
- Hip Flexors
Execution:

- Lift your legs slightly off the ground and kick them up and down in a small, rapid motion.
Why it’s Effective:
Flutter Kicks are particularly effective for targeting the lower portion of the rectus abdominis. The small, controlled movements help build endurance and strength in the lower abs, which are often under-targeted in other exercises (Sarti et al., 1996).
9. Side Plank
How it Works:
The Side Plank is a static exercise that targets the obliques and transverse abdominis, enhancing lateral core stability.
Muscles Targeted:
- Internal and External Obliques
- Transverse Abdominis
- Glutes
Execution:
- Lie on your side with your elbow directly under your shoulder.
- Lift your hips off the ground, creating a straight line from head to heels.
- Hold this position without letting your hips drop.
Why it’s Effective:
The Side Plank is highly effective for improving lateral core stability and strength. Research suggests that exercises like the Side Plank that engage the obliques and transverse abdominis are critical for spinal stability and reducing the risk of lower back pain (Koumantakis, Watson, and Oldham, 2005).
10. Spiderman Plank
How it Works:
The Spiderman Plank is a variation of the traditional plank that incorporates a knee-to-elbow movement, further engaging the obliques and rectus abdominis.
Muscles Targeted:
- Rectus Abdominis
- Internal and External Obliques
- Hip Flexors
Execution:
- Start in a forearm plank position.
- Bring one knee towards the elbow on the same side, then return to the starting position.
- Alternate sides while maintaining a strong plank position.
Why it’s Effective:
The Spiderman Plank adds a dynamic element to the traditional plank, increasing the engagement of the obliques and improving core strength and stability. A study in the Journal of Strength and Conditioning Research highlighted that dynamic plank variations like the Spiderman Plank provide superior core muscle activation compared to static planks (Escamilla et al., 2016).
