The best workout for abs, for your situation

The best ab workout treats your abs like any other muscle: a loaded crunch, a hanging knee raise and a cable woodchop for 8 to 15 reps, taken within 1 to 2 reps of failure, about 10 to 20 hard sets a week over two sessions. Add weight when you hit the top of the rep range instead of adding more reps forever. Training builds the muscle, but how much of it you see depends on your body fat, since ab work does not burn the fat over your stomach.

  • Workouts2× a week
  • Working sets19 a week
  • Per workout~25 min
  • EquipmentAdjustable Cable, Pull-Up Bar, Decline Bench, Barbells

Intermediate lifters with cables and a pull-up bar who want thicker, more visible abs from two short sessions added to their split.

Abs grow like any other muscle, so this plan trains them with loads you can add to every week: a cable crunch and a weighted Decline Crunch for 8 to 12 reps, a rollout for 6 to 12, and hanging knee raises for the bottom of the six-pack. Woodchops and plate side bends give your obliques 6 sets a week, and the front of your abs gets 13, for 19 hard sets in all. Most sets stop 1 rep short of failure; the rollout stops at 2 because form breaks first.

Abs A: Crunch and Raise
ExerciseSets × repsRIRRest
Cable Crunch1 warm-up set firstCurl your ribs to your hips, hips stay still 4 × 8–12 1 90 s
Hanging Knee RaiseTailbone lifts at the top, no swinging 3 × 8–15 1 90 s
Cable WoodchopSets are per side, turn from the ribs 3 × 10–15 1 1 min
Abs B: Crunch and Rollout
ExerciseSets × repsRIRRest
Decline CrunchHug a plate to your chest once 12 is easy 3 × 8–12 1 90 s
Barbell RolloutStop the rep before your lower back sags 3 × 6–12 2 90 s
Plate Side BendSets are per side, weaker side first 3 × 10–15 1 1 min
How to run it
Do Abs A and Abs B on different days, at the end of any two workouts at least a day apart.
How to progress
Use double progression: once every set reaches the top of the rep range at the target RIR, add the next weight on the stack or a heavier plate. On the knee raise, progress to straighter legs before adding a dumbbell between your feet.

  • Workouts2× a week
  • Working sets12 a week
  • Per workout~10 min
  • EquipmentDumbbells

Lifters training at home, or anyone new to direct ab work, with a floor and one dumbbell.

Newer lifters grow on less, so this is one routine of 6 hard sets, done twice a week for 12 sets in all. With only a dumbbell to load, the rep ranges run higher, 8 to 20, and every set stops 2 reps short of failure while you learn to curl your spine instead of yanking with your neck or hip flexors. The crunch and reverse crunch cover the top and bottom of your abs, and the dumbbell woodchop covers your obliques.

Home Abs
ExerciseSets × repsRIRRest
CrunchHold the dumbbell on your chest once 20 is easy 2 × 10–20 2 1 min
Reverse CrunchRoll your hips off the floor, lower for 3 seconds 2 × 8–15 2 1 min
Dumbbell WoodchopSets are per side, hips stay square 2 × 10–15 2 1 min
How to run it
Run the routine twice a week on non-consecutive days, after your main workout or on its own.
How to progress
Add reps until every set reaches the top of the range, then make it harder: hold the dumbbell on your chest for crunches, slow the lowering on reverse crunches, and pick a heavier dumbbell for woodchops.

Plan 3

Core strength for heavy lifts, crunching bothers your back

  • Workouts2× a week
  • Working sets16 a week
  • Per workout~20 min
  • EquipmentBarbells, Adjustable Cable

Lifters who want a trunk that holds up under heavy squats and deadlifts, or whose lower back complains when they crunch.

This plan trains your abs by resisting movement instead of creating it, so there is no crunching or twisting under load: the rollout trains you to stop your lower back arching, the Pallof press trains you to stop twisting, and the dead bug trains you to keep your spine still while your arms and legs move. Every one of the 8 sets a session, 16 a week, stops 2 reps short of failure, because the goal is perfect position under load.

Core Strength
ExerciseSets × repsRIRRest
Barbell RolloutSqueeze your glutes, roll only as far as you control 3 × 5–10 2 2 min
Pallof PressSets are per side, hold 2 seconds at full reach 3 × 8–12 2 1 min
Dead BugReps per side, lower back stays on the floor 2 × 6–10 2 1 min
How to run it
Do it twice a week, at the end of a lower-body day or an upper-body day, so the rollouts never tire your trunk before heavy squats or deadlifts.
How to progress
Progress the rollout by rolling farther before adding reps, and move to an ab wheel once you can reach full extension for 10. On the Pallof press, add a plate once every set reaches 12 per side with a 2-second hold.

Best workout for core

When people search for a core workout they usually want a trunk that stays stiff under load and a back that stops complaining, not a six-pack. That job is resisting movement: a rollout fights your lower back arching, a Pallof press fights twisting, and a dead bug teaches you to move your limbs without your spine moving. The core plan below uses only those, stops 2 reps short of failure, and goes at the end of a session, not in front of heavy squats or deadlifts.

Best workout for lower abs

Your six-pack is one muscle, so there is no separate lower ab to isolate, but exercises that curl your pelvis up toward your ribs load the bottom of it hardest. A hanging knee raise and a reverse crunch do that, as long as your tailbone actually lifts at the top. If your knees come up but your pelvis stays put, your hip flexors did the work. Both are in the plans below, and you add load by straightening your legs or slowing the lowering.

Best workout for obliques

Your obliques rotate your trunk, bend it sideways and stop it from twisting, so the best oblique workout trains at least two of those with load. A cable or dumbbell woodchop covers rotation, a plate side bend covers side bending, and a Pallof press covers anti-rotation. Train them for 8 to 15 reps per side with the same rep-and-load progression as your other lifts.

The exercises

Loaded crunch, whole six-pack

Cable Crunch

Abs

The cable lets you add weight in small steps, so you can progress a crunch the way you progress a curl. Standing also lets you bend through your whole spine against steady tension.

How to do it

  1. Attach a rope to a high pulley, grab both ends and step back so the stack lifts off its rest.
  2. Hold the rope beside your head, stand with your feet hip-width and soften your knees.
  3. Curl your ribcage down toward your hips, rounding your upper and mid back, until your chest points at the floor.
  4. Let your spine lengthen back to upright under control, keeping your hands fixed beside your head.

Cues

  • Ribs to hips
  • Round your back, don't bow at the hips
  • Hands stay glued to your head

Common mistakes

  • Hinging at the hips so the weight drops without your spine bending. Keep your hips still and think about shortening the distance between ribs and pelvis.
  • Pulling with your arms. Lock your hands in place so only your trunk moves the rope.

Bottom-up curl, lower abs

Hanging Knee Raise

Abs

Lifting your knees and then curling your pelvis up loads the lower part of your abs harder than a crunch does. It also has a built-in progression from bent knees to straight legs.

How to do it

  1. Hang from a pull-up bar with your hands about shoulder-width apart and your legs straight down.
  2. Pull your shoulders slightly down away from your ears so you are not hanging loose.
  3. Bring your knees up toward your chest, then keep going until your pelvis tips up and your tailbone lifts.
  4. Lower your legs slowly to a straight hang and let any swing settle before the next rep.

Cues

  • Tailbone up at the top
  • Lower for 2 seconds
  • Shoulders active, not shrugged

Common mistakes

  • Stopping when your thighs reach parallel. The ab work is in the last part, where your pelvis curls up.
  • Swinging into the next rep. Pause at the bottom, or brush a foot against the floor or a bench to kill momentum.

Loaded rotation, obliques

Cable Woodchop

Abs

Rotation is one of your obliques' main jobs, and the cable gives it a load you can increase. Chopping from high to low also teaches you to turn from your trunk rather than your arms.

How to do it

  1. Set a handle at the top of a cable and stand side-on to it, feet wider than your shoulders.
  2. Reach up and across with both hands to take the handle, arms long.
  3. Pull the handle diagonally down across your body to the outside of your far knee, rotating through your ribs and letting your back foot pivot.
  4. Let the cable pull you back to the start under control, then finish all reps before switching sides.

Cues

  • Turn from the ribs
  • Arms stay long
  • Slow on the way back

Common mistakes

  • Bending your elbows and pulling with your arms. Keep them nearly straight so the turn comes from your trunk.
  • Going too heavy and losing control of the return. Use a load you can stop at any point of the rep.

Full-range sit-up, easy to load

Decline Crunch

Abs

The decline puts your abs under tension from a stretched start, and hugging a plate is an easy way to add load. It trains a longer range than a floor crunch.

How to do it

  1. Lock your feet under the pads of a decline bench and lie back with your hips near the bend of the bench.
  2. Hold your hands beside your head or hug a plate to your chest.
  3. Curl your head, then shoulders, then upper back off the bench and keep curling until your torso is close to upright.
  4. Lower yourself one segment at a time until your shoulders touch the bench, without dropping.

Cues

  • Chin tucked, curl up
  • Exhale on the way up
  • Lower slowly

Common mistakes

  • Sitting up with a flat back. Round your spine on the way up so your abs, not your hip flexors, do most of the lifting.
  • Yanking on your head. Keep your hands light, or cross your arms over a plate.

Swap for: Cable Crunch, Machine Crunch, Plate Sit-Up

Anti-extension, the whole front of the trunk

Barbell Rollout

Abs

Rolling out trains your abs to stop your lower back from arching under a long lever, which is the same job they do in a heavy squat. It is hard enough to work in low rep ranges.

How to do it

  1. Load a barbell with round plates, kneel behind it on a pad and grip it about shoulder-width.
  2. Tuck your pelvis and squeeze your glutes so your back is flat from your knees to your head.
  3. Roll the bar forward slowly, letting your hips and arms move together, as far as you can keep that flat back.
  4. Pull the bar back toward your knees by driving your hands down and back, keeping your hips tucked the whole way.

Cues

  • Glutes tight, ribs down
  • Hips move with the bar
  • Stop before your back sags

Common mistakes

  • Letting your lower back sag at the far end. Shorten the roll-out until you can hold position, then extend it over the weeks.
  • Pushing your hips back first on the return. Keep your hips moving with your chest so your abs do the pulling.

Side bending, obliques

Plate Side Bend

Abs

Bending sideways against a weight trains the side of your trunk through its full range. A plate is easy to grip and comes in small jumps.

How to do it

  1. Stand tall with your feet hip-width and hold a plate at your side with one hand, arm straight.
  2. Put your free hand on your hip or behind your head.
  3. Bend sideways toward the plate as far as you can without twisting or leaning forward.
  4. Pull yourself back past upright with the opposite side of your waist, then finish all reps before switching hands.

Cues

  • Bend straight sideways
  • Shoulders stacked, no twist
  • Come up past center

Common mistakes

  • Leaning forward or rotating as you bend. Keep your chest facing straight ahead, as if your back were against a wall.
  • Bouncing out of the bottom. Pause briefly at the end of the bend.

Top-down curl, easy to start

Crunch

Abs

The crunch needs nothing but a floor, and holding a dumbbell on your chest turns it into a loaded exercise once bodyweight gets easy. It is the simplest way to learn to curl your ribs toward your pelvis.

How to do it

  1. Lie on your back with your knees bent and feet flat, arms reaching toward your knees or holding a dumbbell on your chest.
  2. Breathe out and curl your head and shoulders off the floor until your shoulder blades lift.
  3. Pause for a moment with your ribs pulled down toward your hips.
  4. Lower slowly until your shoulders touch, then start the next rep without resting.

Cues

  • Ribs to hips
  • Exhale fully at the top
  • Chin tucked, neck relaxed

Common mistakes

  • Pulling your head forward with your hands. Reach your arms toward your knees, or hold the dumbbell instead.
  • Sitting all the way up. The work is in lifting your shoulder blades, so keep your lower back on the floor.

Swap for: Decline Crunch, Dumbbell Suitcase Crunch, Toe Touch Crunch

Bottom-up curl, no equipment

Reverse Crunch

Abs

Curling your hips off the floor targets the lower part of your abs without needing a bar to hang from. It is the floor version of the hanging knee raise.

How to do it

  1. Lie on your back with your arms by your sides, palms down, and lift your knees to a 90-degree angle over your hips.
  2. Breathe out and roll your hips off the floor, bringing your knees toward your chest.
  3. Lift until your lower back peels off the floor and your tailbone points up.
  4. Lower your hips back down slowly, one segment of your spine at a time, until your tailbone touches.

Cues

  • Peel your hips up
  • Knees stay bent
  • Three seconds down

Common mistakes

  • Swinging your legs to get your hips up. Start each rep from a still position and keep your knees at the same angle.
  • Pushing hard through your hands. Keep your arms relaxed so your abs lift your hips.

Rotation with a dumbbell

Dumbbell Woodchop

Abs

It gives your obliques loaded rotation when you have no cable. Kneeling locks your hips in place so your trunk has to do the turning.

How to do it

  1. Kneel tall with your knees hip-width and hold one dumbbell by the ends with both hands.
  2. Start with the dumbbell beside your hip, turning your ribs toward that side.
  3. Lift the dumbbell diagonally across your body to above the opposite shoulder, rotating through your trunk.
  4. Bring it back down along the same path under control, then finish all reps before switching sides.

Cues

  • Hips stay square
  • Turn from the ribs
  • Control the way down

Common mistakes

  • Turning your hips with the weight. Squeeze your glutes so only your trunk rotates.
  • Leaning back to lift the dumbbell. Stay tall and pick a lighter weight if you need to.

Anti-rotation, obliques and deep abs

Pallof Press

Abs

The cable tries to twist you and you stop it, which is how your obliques brace in a heavy lift. It is easy on the back and easy to load.

How to do it

  1. Set a handle at chest height and stand side-on to the cable, far enough away that the stack lifts.
  2. Hold the handle in both hands against your chest, feet a bit wider than your hips, knees soft.
  3. Press the handle straight out in front of your chest without letting your torso turn toward the cable.
  4. Hold for 2 seconds with your arms straight, then bring it back to your chest and finish all reps before switching sides.

Cues

  • Hands stay on your midline
  • Ribs down, glutes tight
  • Hold, don't drift

Common mistakes

  • Letting your hands drift toward the cable at full reach. Use a lighter load and keep your hands in line with your sternum.
  • Standing too close so there is no real pull. Step out until holding position takes real effort.

Swap for: Cable Woodchop, Side Plank, Dumbbell Side Plank

Anti-extension, learn to brace

Dead Bug

Abs

It teaches you to keep your lower back still while your arms and legs move, which is the skill every other exercise here relies on. It is low-risk enough to do before heavy lifts.

How to do it

  1. Lie on your back with your arms pointing at the ceiling and your knees bent 90 degrees above your hips.
  2. Press your lower back gently into the floor and breathe out to set your ribs down.
  3. Reach one arm overhead and straighten the opposite leg toward the floor, stopping just above it.
  4. Bring both back to the start and repeat on the other side, keeping your back pinned the whole time.

Cues

  • Lower back stays down
  • Exhale as you reach
  • Slow and smooth

Common mistakes

  • Your lower back arches as your leg lowers. Shorten the reach or keep the knee bent until you can hold position.
  • Rushing the reps. Take about 2 seconds to reach out and 2 to come back.

Questions

Will 100 crunches a day give you abs?

No. Crunches build the muscle but don't burn the fat over it: in a 6-week trial, people who did ab exercises five days a week with their diet held steady lost no belly fat compared with people who didn't. You also stop gaining from 100 easy reps quickly. Fewer, harder sets you can add weight to build more muscle, and a calorie deficit is what reveals it.

What is the best workout for lower abs?

A hanging knee raise and a reverse crunch, done so your pelvis curls up at the top. Your six-pack is one muscle, so you can't isolate the lower part, but these bottom-up exercises load it hardest.

What ab workouts hit the obliques?

Any loaded rotation, side bend or anti-rotation exercise: cable or dumbbell woodchops, plate side bends and Pallof presses. Crunches and rollouts also work the obliques, but not as their main job.

How often should you train abs?

Twice a week is a good default, with about 10 to 20 hard sets in total for intermediates and fewer for beginners. Splitting the same sets over more days grows the muscle at least as well as one long session, so pick whatever fits your week.

Is it better to train abs with weights or high reps?

Both grow muscle when sets end close to failure, and anywhere from about 6 to 30 reps works. Weights make it easier to get there in fewer reps and to keep progressing, which is why the gym plan uses cables and plates.

What are the best core exercises for strength?

Exercises that make you resist movement: a rollout to resist your back arching, a Pallof press to resist twisting and a dead bug to keep your spine still while your limbs move. They carry over to holding position under a heavy bar.

How fast can you get a six-pack?

It depends on how much body fat you have to lose, not on which ab workout you pick. Train your abs hard twice a week so the muscle is there, and expect visible change on the timeline of your fat loss.
