Flutter Kicks vs Scissors for Abs: Benefits & Muscles Worked

Key Takeaways

• Flutter kicks primarily target the lower abs with an up-and-down motion, while scissor kicks engage more adductor muscles with a horizontal crossover movement.
• Scissor kicks are generally more challenging than flutter kicks, requiring greater core stability and muscle control through complex horizontal movement patterns.
• Both exercises effectively build core strength without equipment, but target different muscle groups for comprehensive abdominal development.
• Flutter kicks are ideal for beginners building foundational core strength while scissor kicks offer progression for those seeking more advanced core challenges with increased time under tension
• SOLE Equipment Mat provides the cushioned surface essential for both exercises, protecting your lower back and tailbone during floor-based ab work.

What's the Difference Between Flutter Kicks and Scissors?

The primary distinction between flutter kicks and scissor kicks lies in the movement pattern. Flutter kicks involve an up-and-down motion with alternating legs, similar to a swimming flutter kick. 

Your legs move vertically, with one leg rising slightly higher than the other in an alternating pattern. The movement is typically quicker and more rhythmic.

Scissor kicks, on the other hand, involve a horizontal, crisscrossing motion. Your legs move laterally away from each other and then cross over—like scissors cutting through paper. This horizontal movement pattern engages different muscle groups, particularly the adductors (inner thighs), which aren't as heavily targeted during flutter kicks.

Another key difference is the level of difficulty. Scissor kicks generally require more core control and stability than flutter kicks, making them a more advanced exercise. 

The horizontal movement pattern challenges your core to maintain proper positioning throughout the exercise, which can be more demanding for beginners. 

Muscles Worked During Flutter Kicks

Primary Target: Lower Abs and Hip Flexors

The main focus of flutter kicks is the rectus abdominis, particularly the lower portion. These muscles work continuously throughout the movement to stabilize your torso and control the position of your legs. 

Your hip flexors (iliopsoas) are heavily recruited during flutter kicks to raise and lower each leg in the alternating pattern.

Secondary Muscles Engaged

Beyond the primary muscle groups, flutter kicks also recruit several secondary muscles. Your quadriceps work to keep your legs straight throughout the movement, while your core stabilizers, including the transverse abdominis and obliques, fire consistently to maintain proper form.

The gluteal muscles also activate during flutter kicks, particularly as you lower each leg with control. This engagement helps stabilize your pelvis and contributes to maintaining proper form. 

Muscles Worked During Scissor Kicks

Scissor kicks take core training to another level by introducing a different movement pattern that challenges your muscles in new ways through horizontal scissoring motion.

Core Engagement: Transverse Abdominis and More

The transverse abdominis, often called the body's natural weight belt, gets a serious workout during scissor kicks. This deep core muscle wraps around your midsection and provides critical stability.

During the crossing motion of scissor kicks, your transverse abdominis works overtime to prevent your lower back from arching and to maintain proper pelvic positioning.

Your rectus abdominis also engages strongly throughout scissor kicks, with particular emphasis on the lower portion. The obliques, both internal and external, fire continuously to control the lateral movement of your legs. 

Lower Body Activation

One of the most distinctive aspects of scissor kicks is their significant engagement of the adductor muscles. 

These inner thigh muscles work eccentrically as your legs separate and concentrically as they cross, creating a comprehensive training effect that flutter kicks don't provide to the same degree.

Your hip abductors (outer thigh muscles) also get substantial work during the phase where your legs move apart. This balanced training of both adductors and abductors contributes to better hip stability and functional strength. 

The quads remain engaged throughout the movement to keep your legs straight, while your hamstrings work isometrically to stabilize your leg position.

5 Key Benefits of Flutter Kicks

Flutter kicks offer numerous advantages for core training making them a valuable addition to any fitness routine regardless of experience level.

1. Beginner-Friendly Ab Conditioning

Flutter kicks provide an accessible entry point into dynamic core training. The straightforward up-and-down movement pattern is intuitive to learn and execute properly, making it ideal for those new to fitness. The movement also allows for easy modification by adjusting the height of your legs or the speed of execution.

2. Minimal Equipment Needed

Flutter kicks require nothing more than your body and comfortable floor space, making them perfect for home workouts or travel. 

3. Endurance Development

The sustained contraction required during flutter kicks builds muscular endurance in your core. This endurance translates to better performance during longer workouts and improved stamina in daily activities requiring core stability.

4. Lower Ab Definition

Regular flutter kick practice specifically targets the lower rectus abdominis, helping develop definition in this often-stubborn area. When combined with proper nutrition for fat loss, flutter kicks contribute to visible abdominal development.

5. Improved Hip Mobility

The dynamic leg movement in flutter kicks promotes hip flexor flexibility and range of motion. This improved hip mobility benefits activities from running to weightlifting, reducing the risk of compensatory movement patterns that can lead to injury.

5 Major Benefits of Scissor Kicks

Scissor kicks deliver unique advantages through complex movement patterns that challenge your core stability and inner thigh muscles comprehensively.

1. Advanced Core Strengthening

Scissor kicks provide a more complex training stimulus than flutter kicks, challenging your core through multiple planes of motion. The anti-rotation component develops functional strength that transfers directly to sports and daily activities.

2. Adductor and Inner Thigh Toning

The horizontal crossing motion uniquely targets the adductor muscles, providing inner thigh strengthening that few bodyweight exercises can match. This balanced lower body development improves hip stability and athletic performance.

3. Enhanced Core Stability

The wider range of motion and crossing pattern in scissor kicks demands exceptional core stability. This develops the deep stabilizing muscles essential for maintaining proper posture and protecting your spine during complex movements.

4. Improved Hip Flexor Function

Regular practice of scissor kicks leads to noticeable improvements in hip flexor strength and mobility. This enhanced hip function translates to better performance in everyday activities like walking and climbing stairs, as well as athletic movements.

5. Greater Calorie Burn

Scissor kicks typically create a higher metabolic demand than flutter kicks due to their more complex movement pattern and greater muscle recruitment. This increased energy expenditure makes scissor kicks valuable for workouts aimed at fat loss alongside core strengthening.

Frequently Asked Questions (FAQs)

Are flutter kicks or scissors better for lower abs?

Both exercises effectively target the lower abs, but in different ways. Flutter kicks create more constant tension in the lower rectus abdominis through the vertical leg movement pattern. Scissor kicks engage the lower abs while also requiring more oblique and transverse abdominis activation due to the rotational component of the crossing motion. 

How many flutter kicks and scissors should I do for effective results?

For flutter kicks, aim for 2–4 sets of 30–60 seconds, focusing on maintaining proper form throughout. With scissor kicks, start with 2–3 sets of 15–20 repetitions per side. As your core strength improves, gradually increase the duration for flutter kicks and repetitions for scissor kicks.

Can I do flutter kicks and scissors every day?

While these exercises are generally safe for frequent practice, your core muscles benefit from recovery periods like any other muscle group. For optimal results, incorporate them into your routine 3–4 times per week, allowing at least one day between sessions for recovery. If you do want daily core work, consider alternating between flutter kicks, scissor kicks, and other complementary exercises to prevent overtraining specific movement patterns and allow different muscle fibers time to recover.

Which exercise is safer for someone with lower back pain?

For individuals with lower back issues, flutter kicks with modified form are typically the safer starting point. Begin with bent knees and a smaller range of motion, ensuring your lower back remains firmly pressed into the Equipment Mat throughout the movement. Place your hands under your glutes for additional support. With scissor kicks, the wider range of motion creates more potential for lower back strain if core strength is insufficient to maintain proper positioning.
