Scissor Kicks: How to Do Them, Benefits & Muscles Worked
Scissor kicks are a no-equipment core exercise that builds abdominal endurance while challenging your hip flexors and pelvic control. You perform them lying on your back with both legs hovering above the floor, alternately crossing one leg over the other.
The exercise looks simple, but the real goal is not speed or an extremely low leg position. It is keeping your ribs, pelvis, and lower back controlled while your legs move. Below, you will learn the correct technique, muscles worked, benefits, common mistakes, variations, and how to program scissor kicks for your fitness level.
How to Do Scissor Kicks
Quick instructions: Lie on your back, brace your core, lift both straight legs, and alternate crossing one leg over the other without letting your lower back arch.
- Set up: Lie faceup on an exercise mat with your legs extended. Place your arms by your sides, palms down. If you need extra support, slide your hands beneath your hips.
- Brace your core: Gently draw your ribs toward your pelvis and press your lower back toward the mat. Think about preparing your midsection for a light punch.
- Lift your legs: Raise both heels several inches off the floor. Start higher if lowering your legs causes your back to arch.
- Begin the crossover: Keep your legs long and cross your right leg over your left.
- Switch sides: Open your legs slightly, then cross your left leg over your right.
- Continue with control: Alternate sides at a smooth pace while breathing steadily. Keep your neck, jaw, and shoulders relaxed.
- Finish the set: Stop before your lower back lifts, your knees bend excessively, or the movement becomes rushed.
Best form cue: Use the lowest leg position you can control. Raising your legs makes the exercise easier and is better than forcing a low position with poor form.

Muscles Worked by Scissor Kicks
Scissor kicks recruit several muscles at once to hold your torso steady and move your legs:
- Rectus abdominis: helps control the relationship between your rib cage and pelvis.
- Transverse abdominis: contributes to deep abdominal bracing and spinal stability.
- Obliques: resist unwanted trunk and pelvic rotation as the legs cross.
- Hip flexors: keep your legs elevated and guide the repeated movement.
- Quadriceps: help maintain straight knees.
- Adductors: assist as the legs move toward and across the midline.
Scissor kicks are often described as a “lower-ab exercise,” but the lower portion of the rectus abdominis is not an independent muscle. The entire abdominal wall works to stabilize your trunk, even if you feel more effort near the lower abdomen.
Benefits of Scissor Kicks
1. Build Core Endurance
Your abdominal muscles stay active for the entire set. This makes scissor kicks useful for building the endurance needed to maintain trunk position during strength training, running, martial arts, and everyday movement.
2. Improve Pelvic Control
The alternating crossover teaches you to keep your pelvis steady while your legs move independently. That coordination can support more efficient kicking, sprinting, and changes of direction.
3. Train Anywhere
No machine or weights are required. Scissor kicks fit easily into a home workout, hotel-room routine, warm-up, finisher, or short core circuit.
4. Adjust the Difficulty Easily
You can change the leg height, knee bend, speed, range, or set length. Beginners can shorten the lever, while experienced exercisers can use a slower tempo or a more demanding hollow-body position.
5. Add Variety to Core Training
Scissor kicks provide a dynamic alternative to static holds. They work best as one part of a balanced routine that also includes anti-extension, anti-rotation, side-stability, and posterior-chain exercises.
Common Scissor-Kick Mistakes
- Arching your lower back: This is the most important error to correct. Raise your legs, bend your knees, shorten the set, or switch to an easier exercise.
- Chasing a very low leg position: Lower is only harder when you can maintain control. Technique matters more than how close your heels are to the floor.
- Using momentum: Fast, loose crossovers reduce the stability challenge. Slow down and make each switch deliberate.
- Holding your breath: Breathe continuously. A steady exhale can help you maintain abdominal tension.
- Tensing your neck: Keep your head supported and shoulders relaxed. Do not pull your chin aggressively toward your chest.
- Taking an excessive range: A small-to-moderate crossover is enough. Large swings can encourage pelvic movement.
- Continuing through pain: Stop if you feel sharp or increasing pain in your back, hips, or groin.
Scissor Kicks vs. Flutter Kicks
The names are sometimes used interchangeably, but the movements are different. In scissor kicks, the legs cross horizontally over and under each other. In flutter kicks, the legs alternate vertically, with one moving up as the other moves down.
Both exercises challenge the abs and hip flexors. Scissor kicks add side-to-side control and greater involvement from the inner thighs, while flutter kicks emphasize a repeated up-and-down pattern. Choose the version you can perform without losing spinal position.
Scissor-Kick Variations and Modifications
Bent-Knee Scissor Kicks
Keep a slight bend in your knees and hold your legs higher. The shorter lever reduces the load on your abs and hip flexors, making this a good beginner variation.
Hands-Under-Hips Scissor Kicks
Place your hands beneath your hips, palms down, for added support. This can make it easier to prevent your lower back from arching.
High-Angle Scissor Kicks
Keep your feet farther from the floor. You still train the crossover pattern while reducing the anti-extension demand on your core.
Slow-Tempo Scissor Kicks
Take two or three seconds to complete each crossover. Slowing the movement increases time under tension without adding external weight.
Hollow-Body Scissor Kicks
Lift your shoulder blades slightly and maintain a controlled hollow-body position during the crossovers. Use this advanced option only if your lower back stays firmly supported.
Weighted Scissor Kicks
Light ankle weights increase the lever load. Add resistance only after you can perform the standard version smoothly, and begin with a small amount of weight.
How Many Scissor Kicks Should You Do?
Time-based sets let you focus on position instead of counting every crossover:
- Beginner: 2–3 sets of 10–20 seconds
- Intermediate: 3 sets of 20–40 seconds
- Advanced: 3–4 sets of 40–60 seconds or a harder variation
Rest for 30–60 seconds between sets. Two or three core sessions per week is a practical starting point for most people. End each set as soon as your form changes—even if the planned time has not elapsed.
Where Scissor Kicks Fit in a Workout
Use scissor kicks after your main lifts or sport practice, when they will not fatigue your core before exercises that require heavy bracing. For a simple, balanced core circuit, complete two or three rounds of:
- Scissor kicks: 20–30 seconds
- Dead bug: 6–10 reps per side
- Side plank: 15–30 seconds per side
- Bird dog or glute bridge: 8–12 reps
Move slowly, rest as needed, and prioritize consistent form over completing the circuit quickly.
Safety Tips and When to Modify
If you mainly feel scissor kicks in your lower back, raise your legs, bend your knees, place your hands beneath your hips, or substitute a dead bug. Mild muscular effort is normal; sharp, pinching, or radiating pain is not.
People with an existing back, hip, or groin condition—and anyone returning to exercise after surgery, pregnancy, or injury—should get individualized guidance from a qualified healthcare or fitness professional. This article is educational and is not a substitute for medical advice.
Frequently Asked Questions
Are scissor kicks good for your abs?
Yes. Scissor kicks train your abdominal wall to stabilize the pelvis and spine while your legs move. They are especially useful for core endurance, but they should be combined with other movement patterns for complete core training.
Do scissor kicks burn belly fat?
No exercise can selectively remove fat from one area. Scissor kicks can strengthen your core and add to your total activity, while fat loss generally depends on sustained nutrition habits, total energy balance, sleep, and a well-rounded exercise program.
How low should your legs be?
Keep your legs at the lowest height that allows your lower back and pelvis to stay controlled. Beginners often need a higher angle. As your strength improves, you may gradually lower your legs without changing spinal position.
Should your head stay on the floor?
For the standard version, keep your head supported and neck relaxed. Lifting the shoulders creates a harder hollow-body variation, but it is not required for scissor kicks to be effective.
Why do I feel scissor kicks in my hip flexors?
Your hip flexors actively hold and move your legs, so some effort there is expected. If they dominate the exercise or your back arches, raise your legs, bend your knees, shorten the set, and reinforce your abdominal brace.
How often can you do scissor kicks?
Two or three times per week is enough for most people. Allow recovery after challenging sessions and avoid the exercise if it causes pain.
Final Takeaway
Scissor kicks are a convenient way to build core endurance, strengthen your ability to control the pelvis, and train without equipment. Start with short sets and a higher leg position, keep your lower back supported, and progress by improving control before adding duration or resistance.
