The 6 Best Pilates Core Exercises (And How to Do Them Right)

Your core is not your six-pack — and until you understand that, you'll keep training it wrong.

Why Pilates Core Work Is Different (It's Not About Crunches)

Traditional ab training fixates on the rectus abdominis — the visible "six-pack" muscle that runs down the front of your torso. Pilates targets something deeper: the transverse abdominis (your internal corset), the multifidus (the small spinal stabilizers), the pelvic floor, and the diaphragm. Together these form what Pilates calls the "powerhouse" — and building strength here creates a stable, functional core that protects your spine, improves posture, and actually changes how your midsection looks and performs.

The other difference: Pilates core exercises are almost always integrated. Your core works while your arms or legs are moving, not in isolation. That's what makes the work transfer to real life — and to every other sport or activity you do.

The 6 Exercises

The Hundred

Lie on your back, bring your legs to tabletop, lift your head and shoulders off the mat, and pump your arms vigorously — five pumps on the inhale, five on the exhale — for 100 pumps total. The arm movement is small and controlled; the challenge is maintaining a stable spine and deep abdominal connection throughout all 100 counts.

Tip: Keep your lower back imprinted into the mat. If it arches, raise your legs higher toward the ceiling until your spine can stay flat.

Double Leg Stretch

From the same starting position, hug your knees to your chest, then simultaneously reach your arms overhead and extend your legs out to a 45-degree angle — then circle the arms back and pull the knees in. That's one rep. It's a breathing exercise as much as a core exercise: inhale as you extend, exhale as you return.

Tip: Resist the urge to let your ribcage pop up as your arms go overhead. Keep the ribs heavy and the exhale long.

Criss-Cross

Hands lightly behind your head, legs in tabletop. Rotate your right shoulder toward your left knee while your right leg extends long — then switch. This is not a crunch with a twist. The rotation comes from the thoracic spine, not the neck, and the lower body moves in opposition to create full-body length.

Tip: Slow down. Most people rush this. Hold the rotation for a full beat before switching — that's where the obliques actually engage.

Teaser

Start lying flat on your back. Inhale to prepare, then exhale as you roll up through your spine into a V-shape — legs extended and lifted, arms reaching forward parallel to your legs, spine long. Hold for a breath, then roll back down with control. This is an advanced movement that requires significant hamstring flexibility and deep core strength to do cleanly.

Tip: If your lower back rounds or your legs drop, bend your knees slightly and build the full range over time. Don't force it — the payoff comes from doing it right, not from getting into the shape at any cost.

Plank with Leg Lift

Start in a forearm plank with your body in a straight line from heels to crown. Slowly lift one leg 6–8 inches off the floor, hold for 2 seconds, lower, and switch. The core's job here is to resist rotation as the leg moves — that anti-rotation demand is the entire point of the exercise.

Tip: If your hip drops or rotates when you lift the leg, your core isn't stabilizing correctly yet. Slow down further, or spend more time in the plank itself before adding the lift.

Rolling Like a Ball

Sit at the front of your mat, knees hugged to your chest, feet lifted off the floor, spine in a deep C-curve. Roll back to your shoulder blades on an inhale, then roll back up to balance on the exhale. This isn't momentum — it's control. You're using the curve of your spine to create the rolling sensation, not throwing yourself backward.

Tip: Keep your gaze on your knees throughout. The moment you look away, you lose the C-curve and the exercise breaks down.

How to String These Into a Core Routine

Do these in order — that's not arbitrary. The sequence was designed intentionally: The Hundred warms the core and establishes breath rhythm, the stretches develop length and abdominal connection, Criss-Cross targets the obliques directly, Teaser integrates everything into full-body stability, Plank with Leg Lift moves into functional anti-rotation, and Rolling Like a Ball closes the session with spinal articulation and release.

For a complete core session, run through the sequence 2–3 times. Start with 5–8 reps per exercise and build from there as your endurance and control improve. Aim for 3 sessions per week on non-consecutive days — core muscles need recovery time like any other muscle group.

If you want this sequenced into a guided session you can actually follow in real time, our core-focused routines walk you through every exercise with timing and cues built in. No guesswork, no pausing to re-read instructions.
