Key Highlights:

• LE SSERAFIM’s Kazuha demonstrated a 5-exercise ab circuit: in and out (10), scissors (15), rainbow (10), high and low (10), knee tuck variation (10); perform 3 full sets.
• The routine targets upper, lower, and oblique muscles with compact, equipment-free movements suitable for home or travel; clear form, progressions, and programming make it adaptable for beginners through advanced trainees.

Introduction

A short clip of LE SSERAFIM’s Kazuha training core muscles has generated widespread attention—fans and fitness-minded viewers noticed not only the choreography of the moves but her controlled strength and endurance. The routine itself is compact and purposeful: five distinct movements, modest rep ranges, and three full sets. That mix makes it both a practical daily core session and a useful component of a larger fitness program.

This article translates that short demonstration into a complete, actionable guide. It presents exact instructions for each exercise, explains what each movement targets, identifies common technical mistakes, and outlines warm-up, recovery, and progression strategies. Whether the goal is functional strength for dance and sport, improved posture, or aesthetic abdominal definition, you’ll find ways to adapt the circuit to your current level and long-term goals.

What Kazuha’s Circuit Looks Like — The Sequence and Rep Scheme

The workout is designed as a circuit: perform each exercise in order with minimal rest between movements, then rest between sets. According to the clip, the sequence and prescribed repetitions are:

1. In and out — 10 reps
2. Scissors — 15 reps
3. Rainbow — 10 reps
4. High and low — 10 reps
5. Knee tuck variation — 10 reps

Complete all five moves to constitute one set, then repeat the entire circuit for a total of three sets. The original post clarifies that one rep equals the full movement cycle returning to the start position.

The following sections break down each exercise with step-by-step cues, what the movement trains, common errors and how to fix them, plus gradual variations.

Exercise 1 — In and Out (10 reps)

What it is: The in-and-out—also called seated in-and-out or V-sit in-and-out—combines a hollow-body contraction with a leg drive. It challenges the rectus abdominis and hip flexors while training coordination and stability through the midline.

How to perform it:

• Start seated or semi-reclined on the floor with your hands lightly supporting behind your hips or extended beside you for balance.
• Extend your legs out and lean back slightly, engaging the core to maintain a long, hollow position.
• Draw your knees toward your chest while simultaneously bringing your torso forward so your body forms a compact “V.”
• Reverse the motion: extend legs and lean back to the starting hollow position with control.
• One rep counts when you return to the starting position.

Coaching cues:

• Keep the spine long; avoid rounding aggressively at the lower back.
• Breathe: exhale during the crunching/tucking phase, inhale as you extend out.
• Move with control. The return (extension) should be deliberate to resist momentum.

Common mistakes and corrections:

• Overrelying on hip flexors: focus on initiating the curl from the ribs moving toward the pelvis, not just pulling the legs with the thighs.
• Collapsing the chest: maintain open chest and neck alignment to prevent strain.
• Swinging the arms for momentum: keep hands passive and use the core for the drive.

Regressions and progressions:

• Regress: keep hands on the floor behind you for more support; perform fewer reps or reduce range of motion—bring knees halfway in.
• Progress: add ankle weights, pause in the fully tucked position for 1–2 seconds, or perform the movement with a slower eccentric (3–4 seconds to extend).

Why it’s included:

• Efficient mix of hip flexion and trunk flexion that recruits both upper and lower abdominal fibers while improving coordination—useful for dancers who need midline control during turns and jumps.

Exercise 2 — Scissors (15 reps)

What it is: Scissors are a lower-ab focused leg movement performed on the floor. They emphasize eccentric control of the lower abs and hip flexors while training the stabilization of the pelvis.

How to perform it:

• Lie on your back with your hands under your hips for support or by your sides if comfortable.
• Lift both legs a few inches off the ground to engage the lower abdominals.
• Alternately lower one leg toward the floor while raising the other; imagine opening and closing a pair of scissors.
• Keep the lower back pressed gently into the floor—if the back lifts, reduce the range of motion.

Coaching cues:

• Maintain steady breathing; exhale as you lower each leg and inhale when returning.
• Keep the movement slow and deliberate; the lowering leg should descend with control.
• Neutral pelvis: avoid tilting the hips excessively.

Common mistakes and corrections:

• Allowing the lumbar spine to arch: place hands under the hips or tilt the pelvis to keep the low back supported.
• Rapid, uncontrolled swings: reduce range until you can descend slowly for a count of 3–4.
• Neck tension: keep the head relaxed on the floor.

Regressions and progressions:

• Regress: perform single-leg lowers with the opposite knee bent and foot planted; this reduces load while preserving stimulus.
• Progress: perform the scissors with legs higher off the floor, increase the tempo slightly while maintaining control, or add a resisted band around the ankles.

Why it’s included:

• Targets the lower portion of the rectus abdominis and reinforces pelvic stability—key for stability in dance landing mechanics.

Exercise 3 — Rainbow (10 reps)

What it is: “Rainbow” typically describes a wide, arcing leg movement that traces a rainbow shape across the body, engaging obliques and the entire midline. It’s a dynamic move that mixes the demands of lateral control with rotational stabilization.

How to perform a common rainbow variant:

• Lie on your back with legs extended and arms out wide for balance.
• Lift legs together and draw them in an arc from one side of the body to the other—imagine tracing a rainbow over the torso.
• Control the arc with the obliques; avoid letting the lower back peel excessively from the floor.
• Return to center and repeat the arc to the opposite side; one complete arc counts as one rep if you return to the center each time.

Coaching cues:

• Keep ribs down and core braced. The movement should come from the midsection, not from momentum created by the legs.
• Move through the obliques: think of the ribs moving toward the hips.
• Use the arms as stabilizers; palms can press lightly into the floor.

Common mistakes and corrections:

• Over-rotating the lower back: keep the range within comfort and control.
• Letting the legs swing: slow down and focus on oblique contraction.
• Holding breath: keep the breath flowing—exhale on the arc toward the side.

Regressions and progressions:

• Regress: bend the knees slightly to shorten the lever arm and reduce the load on the lower back.
• Progress: perform the movement with straight legs lifted higher, add a small hold at the endpoint, or perform on a decline bench for greater load.

Why it’s included:

• Rainbow trains rotational strength and oblique engagement, improving trunk control during lateral and rotational dance moves. It also introduces a challenge to spinal stability.

Exercise 4 — High and Low (10 reps)

What it is: The “high and low” movement likely alternates between lifting the legs high (toward vertical) and lowering them low toward the ground, while maintaining abdominal tension. It’s an anti-extension exercise emphasizing the ability to resist spinal arching under load.

How to perform a standard high-low leg raise:

• Lie on your back with hands under your hips or extended by your sides for support.
• Lift both legs to about 90 degrees (high position) while bracing the abs.
• Slowly lower the legs toward the floor to a low position just above the ground, then lift them back to the high position.
• One rep equals a complete cycle from high to low to high.

Coaching cues:

• Keep the lower back pressed into the floor throughout. If contact is lost, raise legs less high or bend the knees slightly.
• Exhale as you lower the legs; inhale as you lift them back up.
• Maintain a steady tempo: slow on the lowering, controlled on the lift.

Common mistakes and corrections:

• Letting the lumbar spine arch: reduce range or place hands under the pelvis for feedback.
• Swinging the legs: control the eccentric phase and pause briefly at the low point if necessary.
• Neck strain: keep the head relaxed or supported.

Regressions and progressions:

• Regress: perform alternating knee tucks rather than simultaneous leg lowers; perform high-and-low with a single leg at a time.
• Progress: add ankle weights or slow the eccentric to 4–5 seconds; perform with straight legs and aim for a lower endpoint.

Why it’s included:

• Reinforces anti-extension capacity of the core—the ability to stop the spine from arching under the lever of the legs. Anti-extension is foundational for posture and athletic tasks.

Exercise 5 — Knee Tuck Variation (10 reps)

What it is: Knee tucks can be executed from different positions—plank knee tucks using sliders, captain’s chair knee tucks, or seated V-sit knee tucks. The version shown appears to be a variation emphasizing dynamic tuck movement that engages the lower abs and hip flexors while challenging balance.

How to perform a basic seated knee tuck:

• Begin in a reverse plank or V-sit position, supporting yourself with hands behind you (for the seated variant) or on a stable surface for the suspended/slider variant.
• Draw the knees toward the chest while rounding the upper body slightly, then extend the legs back out to the starting position.
• Keep the movement controlled and avoid using momentum.

How to perform a plank knee tuck (slider) variant:

• Begin in a high plank with feet on sliders or towels on a smooth floor.
• Drive the knees forward toward the chest (tucking) while keeping the upper body stable, then slide them back to full plank.
• Maintain a neutral spine and braced core throughout.

Coaching cues:

• Anchor the shoulders; the motion should come from the hips and core rather than collapsing at the chest.
• Exhale during the tuck and inhale on the extension.
• Keep hip position steady—avoid rocking or shifting weight excessively.

Common mistakes and corrections:

• Letting hips sag in the plank variation: raise hips slightly and focus on abdominal activation.
• Using momentum: slow down and lengthen the eccentric phase.
• Hands too close to hips in seated variant: position hands for a comfortable, stable base.

Regressions and progressions:

• Regress: perform seated knee tucks with hands on the floor behind you and keep feet nearer the ground to shorten the lever arm; or perform mountain climbers in a slower, controlled manner.
• Progress: increase range of motion, add a push-up between tucks for added demand, or perform tucks from suspension straps for greater instability.

Why it’s included:

• Knee tucks combine anti-extension and dynamic hip flexion in a way that demands both strength and stability. They’re functional for dancers who need rapid core engagement in transitions.

Why This Mix Works: Muscular Emphasis and Training Goals

The selected exercises cover the primary demands of an effective core program:

• Rectus abdominis (upper and lower): in-and-out, high-and-low, scissors prioritize vertical flexion and anti-extension demands.
• Obliques and rotators: rainbow and in-and-out variations emphasize rotational and lateral control.
• Anti-extension and pelvic stability: high-and-low and scissors reinforce the ability to resist unwanted lumbar extension under load.
• Coordination and dynamic control: the sequence requires rapid transitions and sustained midline tension, translating to better performance in dance, athletics, and everyday tasks.

The protocol—moderate reps and three sets—balances strength and muscular endurance. For performers like Kazuha, that blend supports repeated muscular contractions across a performance while maintaining fine control.

Warm-Up and Mobility: Preparing the Body for the Circuit

A targeted warm-up improves performance and reduces injury risk. Spend five to ten minutes before the circuit to raise core temperature and prime the nervous system.

Suggested warm-up sequence:

• Light aerobic movement (2–3 minutes): brisk walking, marching in place, or skipping rope to increase heart rate.
• Dynamic hip mobility (1–2 minutes): leg swings front-to-back and side-to-side, gentle hip circles.
• Active spinal warm-up (1–2 minutes): cat-cow flows and seated trunk rotations to lubricate the lumbar and thoracic spine.
• Core activation drills (2–3 minutes): dead bug (8–10 reps per side), bird dog holds (6–8 reps per side), and glute bridges (10–12 reps). These establish neural connection to the core and glutes before loaded or dynamic work.

Avoid cold, maximal-intensity attempts at the outset. If you feel tight in the hips or lower back, prioritize mobility before starting the circuit.

Cooling Down and Recovery

After the circuit, invest five to eight minutes in easy movement and mobility to help the nervous system unwind and reduce soreness.

Suggested cool-down:

• Gentle hamstring and hip-flexor stretches: hold each 20–30 seconds per side.
• Child’s pose or supine knees-to-chest: 30–60 seconds to relieve lower back tension.
• Foam rolling the thoracic spine and glutes: 1–2 minutes where needed.
• Controlled breathing: lie supine and practice diaphragmatic breathing for one to two minutes to reset the nervous system.

Recovery outside the session:

• Sleep: prioritize consistent sleep to aid muscular recovery and hormonal regulation.
• Nutrition: fuel workouts with balanced meals and adequate protein to support repair and adaptation.
• Hydration: maintain fluid intake; it supports muscle function and reduces cramping risk.

Programming: How to Fit This Circuit Into a Weekly Plan

The circuit functions well as a stand-alone core session, a finisher after a strength or dance rehearsal, or as a daily quick core routine. Here are sample weekly structures for different goals.

For general fitness and posture (3x per week):

• Monday: Full-body strength session + 1 circuit (3 sets)
• Wednesday: Cardio or dance practice + mobility
• Friday: Full-body strength session + 1 circuit (3 sets)
• Optional light core activation on other days (1–2 exercises, 1–2 sets)

For performers/dancers needing endurance and control (4–5x per week):

• Short daily core circuit: 3 sets of Kazuha’s routine on performance days.
• On heavy rehearsal days: reduce to 1–2 sets to avoid fatigue before performance.
• Pair with mobility, leg strength, and plyometric work twice weekly.

For fat-loss and visible abs (combined approach):

• Core training 2–3 times per week (this circuit or variations)
• Strength training 2–3 times per week
• Cardio 2–4 times per week (mix of high-intensity intervals and steady-state)
• Implement a sustainable calorie deficit if reducing body fat is the objective.

Progression strategies:

• Increase repetitions modestly (add 2–5 reps per exercise across a 2–4 week period).
• Add a fourth set once the three-set protocol feels easy.
• Slow the tempo (e.g., 3–4 second negatives) to increase time under tension.
• Introduce instability (sliders, small medicine ball tosses, or suspension trainers) after establishing solid form.

Frequency guidance:

• Beginners: 2–3 times per week with at least one day of rest between sessions.
• Intermediate/Advanced: up to 5 times per week if volume per session is adjusted and recovery is sufficient.

Modifying for Different Levels

Beginner modifications:

• Reduce rep counts (e.g., half the prescribed reps).
• Shorten range of motion (e.g., knees slightly bent during leg lowers).
• Use hands under hips for support during scissors and high/low.
• Rest longer between sets (60–90 seconds).

Intermediate adjustments:

• Follow the full circuit as prescribed, but add tempo control (2 seconds up, 2 seconds down).
• Shorten rest (30–45 seconds) to promote endurance.

Advanced strategies:

• Add load (ankle weights, weighted vest), slow eccentrics, or perform the circuit as a superset with another abdominal exercise.
• Decrease rest to 15–30 seconds between movements to increase metabolic demand.
• Combine the circuit with functional movements (e.g., carry or lunge patterns) in a larger training session.

Common Technical Mistakes and How to Fix Them

Many core exercises look simple but fall victim to predictable errors that reduce effectiveness and increase injury risk.

Mistake: Arching lower back during leg lowers (high and low, scissors). Fix: Reduce leg height and keep hands under the pelvis to feel the spine contact. Focus on tilting the pelvis posteriorly (flattening the lower back).

Mistake: Using momentum to complete in-and-out and knee tucks. Fix: Slow the tempo and pause briefly at endpoints. Think of the core doing the work rather than the legs swinging through space.

Mistake: Holding breath during exertion. Fix: Coordinate breath with movement—exhale during contraction or the most effortful phase, inhale during the release.

Mistake: Neck and upper trapezius strain in in-and-out or rainbow variants. Fix: Keep the head neutral, chest open, and avoid pulling on the neck. Use hands for stabilization rather than support under the head.

Mistake: Lack of pelvic stability during rainbow/rotational moves. Fix: Shorten the range to regain control; practice slower rotations and reinforce the movement with side planks or anti-rotation chops.

Consistent feedback—whether from a mirror, a coach, or videoing yourself—helps identify and correct these tendencies. Small form improvements yield large gains.

The Role of Nutrition and Body Fat in Ab Visibility

Strong abdominal muscles are one part of achieving visible abs; body fat percentage is the other. Core training builds the underlying muscles and improves posture and function, but caloric balance determines fat loss.

Guidelines:

• Maintain a modest calorie deficit for gradual fat loss: aggressive deficits reduce performance and recovery.
• Prioritize protein (aim for ~1.6–2.2 g/kg of body weight depending on activity level) to preserve lean mass during deficit.
• Focus on whole foods: vegetables, lean proteins, whole grains, healthy fats.
• Time carbohydrates around workouts if training intensity is high to support performance.

Avoid extreme measures (crash diets) that can reduce energy, increase injury risk, and erode long-term adherence. Sustainable changes to intake, paired with a consistent exercise routine, produce the best results.

Why Core Training Benefits More Than Aesthetics

A well-trained core supports far more than abdominal definition. Relevant outcomes include:

• Spinal stability: improved ability to resist unwanted movements under load—important for lifting, landing, and rotational sports.
• Posture: stronger midline support reduces slumping and compensatory muscle strain.
• Transfer to sport and daily life: better balance and force transfer between lower and upper limbs.
• Injury prevention: a robust core helps distribute forces, reducing overload on the lumbar spine.

Dancers, martial artists, gymnasts, and athletes rely on reliable core control for efficient technique and repeated performance. The circuit demonstrated by Kazuha aligns with functional demands of performance: short bursts of controlled, repeatable core contractions.

Equipment-Free Variants and Simple Add-Ons

One strength of this circuit is that it requires no equipment. That makes it ideal for backstage, travel, or at-home sessions. If you want to add variety or progressive load, consider:

• Sliders or towels under the feet for plank-based knee tucks.
• Ankle weights or resistance bands for leg-based movements.
• Small medicine ball or light dumbbell for seated in-and-out holds or Russian twists as a supplementary exercise.
• Suspension trainers (TRX) for advanced tucking and pike variations.

Additions should never compromise form. Increase resistance only when you can perform the movements precisely.

Real-World Examples: Core Routines from Dance and Athletic Contexts

Performers typically prioritize core strength because it directly impacts control, turnout, and landing mechanics. Comparable approaches appear across disciplines:

• Contemporary dancers often build daily core sessions that mix static holds (planks, side planks) with dynamic controls (leg lowers, roll-ups) to sustain spinal control through long rehearsals.
• Gymnasts practice multiple sets of hollow holds, V-ups, and leg lifts to build the specific endurance needed for tumbling passes.
• Mixed martial artists and fighters integrate rotational medicine ball throws and anti-rotation holds to translate core power into punches and takedowns.

Kazuha’s circuit mirrors those principles by blending anti-extension, rotation, and dynamic tucking—movements that facilitate both stability and expressiveness on stage.

Monitoring Progress: How to Know You’re Improving

Measure progress with both objective markers and subjective observations:

Objective markers:

• Increased reps or sets completed with same form.
• Ability to slow the tempo and maintain tension (e.g., adding 3–4 second negatives).
• Reduced rest needed between sets.
• Improved hold times in hollow positions or planks.

Subjective markers:

• Greater control in dance sequences or daily movements.
• Less perceived fatigue during rehearsals.
• Reduced lower-back discomfort when lifting or bending.

Record workouts, note reps and perceived difficulty, and retest every 2–4 weeks. Small, consistent changes compound into meaningful performance improvements.

Safety Considerations and When to Seek Professional Help

Core training is generally safe, but certain situations require caution:

• Acute low-back pain: avoid loaded abdominal flexion and leg-lowering exercises until pain subsides and consult a healthcare professional.
• Hernia or surgical history: obtain clearance before performing intense core contractions; modify movements to reduce intra-abdominal pressure.
• Pregnancy: after the first trimester, consult a healthcare provider; avoid supine positions and intense V-sit-type work in later stages. Postpartum return-to-exercise should be gradual and guided by a clinician.

If you experience sharp pain, numbness, or persistent discomfort during or after exercises, stop and consult a qualified professional. A certified trainer can provide hands-on cues and individualized regressions to ensure safe progress.

Practical Tips for Consistent Training

• Keep sessions short and focused: the simplicity of this circuit makes it easy to perform consistently.
• Prioritize form before volume: perfecting movement quality accelerates progress more than blindly adding reps.
• Pair core work with compound strength training: squats, deadlifts, and single-leg work develop the posterior chain and provide functional balance.
• Use a training log: track reps, perceived exertion, and notes on form.
• Schedule deloads: every 3–6 weeks, reduce overall volume to allow adaptation.

Consistency outweighs intensity in the long run. A 10–15 minute daily focus done correctly produces better outcomes than sporadic maximal efforts.

Sample Sessions: Beginner, Intermediate, and Advanced

Beginner session (20 minutes)

• Finisher: 3 rounds of 20-second plank-to-pike on sliders or suspension pike
• Cool-down and breathing: 5–7 minutes

Adjust these templates to personal recovery and training demands.

Final Notes on Adapting Celebrity Workouts

A short routine from a performer provides inspiration and a proof-of-concept: compact, targeted core sessions can produce meaningful results when executed with discipline and proper progression. Adapt celebrity or influencer workouts to your fitness level—no single routine fits everyone—and use them as one tool among many in a varied, sustainable program.

The structure of Kazuha’s circuit favors repeatability and specificity for performers. Its core elements—anti-extension, rotational control, and dynamic tucking—are widely applicable, from athletic performance to everyday functional strength.

FAQ

Q: How long should the workout take? A: With three sets and short rests, expect 12–20 minutes of work time, plus warm-up and cool-down. Total time varies by rest intervals and pacing.

Q: How often can I do this circuit? A: Two to five times per week, depending on recovery and overall training load. Start at 2–3 times per week; increase frequency once you can perform the session with solid form and adequate recovery.

Q: Will this routine give me visible abs? A: The circuit strengthens the abdominal muscles but visible abs depend on body fat percentage, genetics, and nutrition. Combine this routine with strength training, cardiovascular activity, and a well-managed diet for best results.

Q: I have lower-back pain—can I do these exercises? A: Proceed cautiously. Modify movements to reduce lumbar load—place hands under the hips for support, decrease leg range, or focus on isometric holds like dead bugs and bird dogs. If pain persists, consult a healthcare professional.

Q: Can beginners do the full rep scheme? A: Beginners should scale down reps and sets and use regressions described earlier. Focus on form and build volume gradually.

Q: What are quick progressions if the routine becomes too easy? A: Increase reps, reduce rest, add a fourth set, slow the eccentric phase of movements, or add light external resistance (ankle weights, bands).

Q: Are there exercises I should add to complement this circuit? A: Include posterior-chain work (glute bridges, Romanian deadlifts), anti-rotation drills (pallof presses), and plank variations to balance anterior core training and build full-body strength.

Q: Is breathing important during these exercises? A: Yes. Exhale during the most effortful phase (e.g., tucking or lifting) and inhale during the release. Coordinated breathing supports intra-abdominal pressure regulation and spinal stability.

Q: Can I do this before a performance? A: Use discretion. On performance days, reduce to one set or perform shorter activation drills so fatigue doesn’t impair movement quality. The goal is to prime the core, not exhaust it.

Q: Do I need special equipment? A: No. The circuit can be done with bodyweight only. Sliders, ankle weights, or a suspension trainer can be introduced later for progression.

Q: How long before I see results? A: Improvements in muscle endurance and control may appear within 2–4 weeks. Visual changes depend on diet and overall body-composition strategies and usually take longer.

Q: Is the routine suitable for teens? A: With adult supervision and attention to form, teens can safely perform these exercises. Avoid maximal loading and ensure balanced overall training under a coach’s guidance.

Q: Can this routine reduce belly fat specifically? A: Spot reduction is not possible. Fat loss requires a systemic caloric deficit. This routine builds the underlying muscle and can be part of a fat-loss plan.

Q: What should I do if I feel neck strain during in-and-out or rainbow? A: Keep the head neutral and avoid lifting the head excessively. Let the shoulders relax and use the abdominal contraction to produce movement rather than neck muscles.

Q: Where can I find reliable instruction if I’m unsure of form? A: Seek a certified strength coach or physical therapist for personalized assessment. Online tutorials are useful, but live feedback accelerates safe progress.

Q: How should I adapt the routine for travel or hotel rooms? A: Keep it bodyweight-only, reduce range if space is limited, and prioritize the warm-up and activation drills to reduce stiffness after travel.

Q: Any tips for staying motivated? A: Short sessions are easier to commit to. Schedule them like appointments, track progress, and mix in movement variety to maintain interest while pursuing long-term goals.

For disciplined practice, consistent form, and sensible progression, this five-move circuit offers a compact, effective way to build the core strength and control showcased by performers like Kazuha.
