Scissor kicks work your lower abs, hip flexors, obliques, and deep core muscles by keeping your legs low while your trunk stays braced.
If you have ever held your legs off the floor and felt your midsection light up, you already know scissor kicks are no joke. The move looks simple, yet it can soon leave your abs shaking and your hips tired. That reaction comes from a mix of muscles working together, not just one area.
What Muscles Do Scissor Kicks Work? Detailed Breakdown
Scissor kicks mainly train the front and sides of your trunk plus the front of your hips and thighs. When you lie on your back and sweep your legs past each other, your core has to stop your lower back from lifting off the mat. At the same time, your hip flexors lift and lower your legs through each small arc.
The big muscles that drive the move sit in the front of the trunk. The rectus abdominis runs from your ribs to your pelvis and handles the classic “six pack” look. The external and internal obliques lie along the sides of your waist and help pull your ribs toward your hips and resist twisting. Deep under those layers sits the transverse abdominis, a belt like muscle that wraps around your middle and tightens to hold your spine steady.
Under the belt line, scissor kicks lean heavily on the hip flexors. This group includes the iliopsoas and rectus femoris, which lift your thigh toward your chest. A guide from Verywell Health on hip flexor muscles notes that these muscles sit near the front of the hip and work through every step you take. In scissor kicks, they hold your legs in the air against gravity while the abs keep your spine stable.
To round things out, smaller helpers pitch in. The inner thigh muscles squeeze slightly to keep the legs from drifting side to side. The lower back and glute muscles keep your pelvis from tilting too far forward or back. When the move feels balanced, every part of this chain shares some of the work.
| Muscle Group | Main Job In Scissor Kicks | How It Feels |
|---|---|---|
| Rectus abdominis | Stops lower back from arching and keeps ribs pulling toward hips | Firm burn through the front of the abs near the belly button |
| External and internal obliques | Steady the trunk and control side to side sway | Warm tension along the sides of the waist |
| Transverse abdominis | Wraps the midsection and stiffens the spine | Deep, tight brace just above the pelvis |
| Iliopsoas and hip flexors | Lift and lower the legs and hold them off the floor | Work felt at the front of the hips and high in the thighs |
| Rectus femoris | Helps flex the hip while the knee stays straight | Burn along the front of the thigh close to the hip crease |
| Glutes | Keep the pelvis from tilting and steady the hips | Light tension in the butt when you press your low back down |
| Lower back stabilisers | Prevent the spine from slipping into an arched position | Gentle tension, not sharp pain, in the low back region |
Muscles Worked By Scissor Kicks In Your Core
Scissor kicks call on both the surface muscles and the deep layers close to the spine. The upper and lower sections of the rectus abdominis fire together as you hold your head and shoulders down and tilt the front of your pelvis toward your ribs. That tilt is what keeps your low back pressed into the mat.
The obliques help in two ways. They steady the rib cage so your legs can move freely, and they stop the hips from twisting as one leg passes the other. Deep under those layers, the transverse abdominis tightens like a belt when you draw your navel gently toward your spine. That deep brace lets your hip flexors do their job without overloading your lower back.
How Scissor Kicks Challenge The Hips And Thighs
Many people feel scissor kicks mainly in the front of the hips. That makes sense, since the hip flexors hold the legs off the floor and guide each small sweep. The iliopsoas sits deep in the front of the hip, and the rectus femoris crosses both the hip and knee. Together they keep the legs long and moving smoothly.
Can I Use Scissor Kicks For Lower Abs?
When people ask what muscles do scissor kicks work? they often mean, “Will this move hit my lower abs?” The short answer is yes, the move trains the lower section of the rectus abdominis, along with the deep core around it. Any time you keep your pelvis tucked and your legs close to the floor, the area just below the navel fires hard.
That said, muscles do not divide cleanly into “upper” and “lower” parts once you see their structure. Coaches use those terms to describe where you feel a move, not separate chunks of tissue. The rectus abdominis runs from ribs to pelvis as one sheet, so scissor kicks simply place more stress on the end near your pelvis.
Form Tips To Target The Right Muscles
Good form turns scissor kicks from a hip flexor grind into a balanced core drill. Use these cues to steer work toward the muscles you want.
Set Up Your Starting Position
Lie on your back with your legs long and your arms by your sides. Press the back of your head into the floor and nod your chin slightly so your neck stays long. Bend your knees, plant your feet, and take a slow breath in.
As you breathe out, tighten your midsection as if bracing for a gentle poke and flatten your low back against the mat. Lift one leg at a time to tabletop, then straighten both knees so your feet point toward the ceiling. Pause here and check that your ribs are still heavy and your breathing steady.
Lower Into The Scissor Position
From the vertical leg position, lower both legs together until they reach a point where your low back just starts to want to peel off the mat. Stop just before that point. This is your working range. One leg moves a little lower while the other moves up, then they switch in a smooth, controlled pattern.
Keep your toes pulled toward your shins and your knees straight, unless your hip flexors feel strained. In that case, bend the knees slightly to shorten the lever and take some load off the front of the hips while you keep the abs engaged.
Breathing And Bracing
Breathe out through the hardest part of the sweep and breathe in as the legs pass through the middle. Match each leg switch to your breath so you do not rush. A steady rhythm keeps the transverse abdominis switched on and stops the lower back from sagging.
Programming Scissor Kicks In Your Workouts
Muscles worked by scissor kicks fit neatly into most core training days. You can plug this move into warm ups, strength blocks, or finishers, as long as you match the set and rep scheme to your current level.
Aim for slow leg sweeps and steady breathing; when your form slips or your low back lifts, stop the set, rest, start your next round.
| Level | Sets And Reps Or Time | Notes |
|---|---|---|
| Beginner | 2–3 sets of 8–10 slow reps per leg | Keep legs higher, bend knees slightly, rest 60 seconds |
| Early intermediate | 3 sets of 10–12 reps per leg | Lower legs closer to the floor while holding a flat back |
| Intermediate | 3–4 sets of 20–30 seconds | Smooth, steady scissor motion with full tension |
| Late intermediate | 4 sets of 30–40 seconds | Add light ankle weights if your back stays happy |
| Hard level with care | 4 sets of 40–60 seconds | Only if you can keep zero arch and no hip pain |
| Core finisher | 1–2 sets of max quality time | Stop when you can no longer hold form, not when pain starts |
| Deload week | 2 light sets of 15 seconds | Use higher leg angles and slower breathing |
Who Should Be Careful With Scissor Kicks
Most healthy lifters can use scissor kicks in some form, yet the move is not a fit for everyone. People with current low back pain, hip flexor strains, or recent abdominal surgery should talk to a doctor or physical therapist before pushing into hard sets.
Scissor Kicks Versus Other Core Exercises
Scissor kicks shine as a low equipment move that targets the front of the trunk and hips at the same time. That said, they sit best inside a plan that also trains rotation, anti rotation, and extension. Mix them with planks, side planks, bird dogs, and exercises from trusted sources such as the ACE abdominal exercise library to build a strong, balanced midsection.
Main Takeaways For Scissor Kicks Training
By now the answer to what muscles do scissor kicks work? should feel clear. The move hits the rectus abdominis, obliques, and transverse abdominis, plus the hip flexors at the front of your thighs. Smaller helpers in the glutes, inner thighs, and low back join in to keep your pelvis steady.
Use crisp form, a tight but smooth brace, and a range of motion that keeps your low back pressed to the mat. Match your sets and reps to your current level and pair the move with other core drills that train different directions of movement. If scissor kicks leave you with sharp hip or back pain, ease off and speak with a qualified health professional before you try the move again.
