Sore abs after a workout: how long it lasts and what helps
Workouts by Tiff and Dan · Updated October 20, 2026
Sore abs after a hard or new ab workout usually show up within a day or two, feel worst 2 to 3 days after the workout, and are mostly gone within about 5 days. It's normal muscle soreness, called DOMS (delayed onset muscle soreness). Easy movement, sleep and normal meals help you feel better while it passes, and the next time you do the same workout you'll usually be much less sore.
Some pain isn't soreness. Dark urine after a hard workout, a new bulge, or sharp pain in one spot need a doctor: see the red flags.

Why your abs get sore
Soreness comes from small-scale damage in the muscle and the repair that follows. It's worst after exercise your muscles aren't used to (Hotfiel 2018). For abs, that usually means:
- New moves, more reps, or harder versions than you normally do.
- Slow lowering. The way down of a sit up, or lowering your legs in a leg raise, works the muscle while it lengthens. That kind of work (eccentric) causes more muscle damage than other kinds (Cheung 2003).
- Coming back after a break.
Your abs tighten when you sit up, cough, sneeze and laugh, which is why all of those can hurt for a few days.
The good news: soreness drops a lot once your body is used to a workout. One session protects against muscle damage from the next similar one, an effect called the repeated bout effect (McHugh 2003).
How long sore abs last
| Time after the workout | What's normal |
|---|---|
| During and right after | Little or no soreness. The burn you feel during a set fades soon after you stop. |
| Day 1 or 2 | Soreness starts: tender to touch, stiff when you sit up |
| Days 2 and 3 | Usually the worst of it |
| Days 4 and 5 | Easing off |
| After a week | Should be gone. If it isn't, see a doctor. |
Soreness usually starts 1 to 3 days after a workout and rarely lasts more than five days (Cleveland Clinic). It typically peaks 48 to 72 hours after the workout (Hotfiel 2018).
How long do abs take to recover between workouts?
About 48 hours after a hard ab workout. The American College of Sports Medicine advises training each muscle group two or three days a week, with at least 48 hours between hard sessions for the same muscles (Garber 2011). Your abs work the same way as any other muscle.
- After a hard ab workout: leave a day before the next one. Every other day works well.
- In between: light core work is fine, like a plank or one of our 5 minute ab workouts done easy.
- Still very sore after two days? Give it another day. Soreness from a new or harder workout often peaks 2 to 3 days later, and it fades faster the more regularly you train.
What actually helps
There's no quick fix: soreness fades with time. These make the wait easier.
- Keep moving gently. Walk, ride a bike easily, or do a light stretch session. Exercise is the best way to ease the ache, though the relief only lasts a while (Cheung 2003).
- Sleep and eat normally. No food cures soreness, but eating enough, including protein, gives your body what it needs to repair.
- Heat or a gentle massage, if they feel good. A warm shower, a bath or a heating pad can be comforting. Massage helps some people, though study results are mixed (Cheung 2003).
- Stretch if it feels good, but don't expect it to speed things up. A Cochrane review found that stretching before or after exercise doesn't meaningfully reduce soreness (Herbert 2011). What it can do is help you feel looser for a while: see the stretches below.
6 stretches for sore abs
These stretch the front and sides of your core, gently. They won't make soreness go away faster, but moving through them often feels better than sitting still, and they're an easy way to move on a rest day.
- How to stretch: go to a gentle pull, never pain, and breathe slowly. Hold each stretch for 10 to 30 seconds and repeat it 2 to 4 times, about a minute in all. That's what the American College of Sports Medicine recommends, and stretching works best when your muscles are warm: after a workout, a walk or a warm shower (Garber 2011).
- When: after an ab workout as part of your cool down, on a rest day while your abs are sore, or any time your core feels tight from sitting.
- Back bends should feel like a stretch, not a pinch. Cobra, camel and the ball stretch all bend your back. If you feel a pinch in your lower back, ease off or skip them. If you've had surgery on your belly, have a hernia, or are pregnant or recently gave birth, check with your doctor first.
| Stretch | How long | Good for |
|---|---|---|
| 1. Full body stretch | 20 to 30 seconds, twice | The whole front of your body. The easiest one |
| 2. Medicine ball back extension | 20 to 30 seconds, twice | Opening up your chest and abs |
| 3. Cat cow | 6 to 8 slow rounds | Moving your spine both ways |
| 4. Cobra stretch | 20 seconds, 2 or 3 times | The front of your abs |
| 5. Kneeling side stretch | 20 seconds each side, twice | Your obliques, along your sides |
| 6. Modified camel | 15 to 20 seconds, twice | The deepest stretch for your abs and hips |
All six take about 6 minutes, in this order: lying down first, then on your hands and knees, then kneeling.
1. Full body stretch
The gentlest way to lengthen your abs, and the place to start when they're very sore.
- Lie on your back with your legs long and your arms on the floor overhead.
- Reach your fingertips one way and your heels the other, as if someone were gently pulling both ends.
- Breathe slowly into your belly. Relax, then reach again.
Hold: 20 to 30 seconds, twice.
2. Medicine ball back extension
Like the full body stretch, but the ball under your lower back lets your chest and abs open up more.
- Sit on your mat with a medicine ball behind you, knees bent and feet flat.
- Lie back over the ball so it sits under your lower back.
- Reach your arms overhead and let your shoulders and head relax toward the floor.
- Come out slowly: arms down first, then roll to your side.
Hold: 20 to 30 seconds, twice.
No medicine ball? A firm pillow or a rolled up towel works. The smaller it is, the gentler the stretch. If it pinches your lower back, skip it: the full body stretch gets you most of the way there.
3. Cat cow
Moves your spine both ways. The cow half gently stretches your abs and the cat half your back. It's also a good warm up before an ab workout.
- Start on your hands and knees, hands under your shoulders and knees under your hips.
- Breathe in as you let your belly drop, lift your chest and look slightly forward (cow).
- Breathe out as you round your back toward the ceiling and tuck your chin (cat).
Do: 6 to 8 slow rounds, moving with your breath.
4. Cobra stretch
Stretches the front of your abs. Start on your forearms and move to your hands when that feels easy.
- Lie face down with your legs long and the tops of your feet on the floor.
- Beginner: put your elbows under your shoulders, forearms flat, and lift your chest.
- Intermediate: put your hands under your shoulders and press up slowly, keeping your hips on the floor.
- Keep your shoulders down, away from your ears.
Hold: 20 seconds, 2 or 3 times. Lift only as far as feels comfortable in your lower back.
5. Kneeling side stretch
Stretches your obliques, the muscles along your sides. They're often the sore ones after twists, side planks and bicycle crunches.
- Kneel on your mat with your knees apart and sit back toward your heels.
- Put your left hand on the floor out to your side.
- Reach your right arm up and over toward the left until you feel a stretch along your right side. Keep your chest facing forward.
- Switch sides.
Hold: 20 seconds each side, twice.
6. Modified camel
The deepest stretch here for the front of your abs and hips. Save it for last, when you're warm.
- Kneel with your knees hip width apart and your toes tucked under.
- Beginner: put your hands on your lower back. Push your hips forward and lift your chest up and back.
- Intermediate: from there, reach back one hand at a time to your heels.
- Keep your hips over your knees and your neck long. Come up slowly, leading with your chest.
Hold: 15 to 20 seconds, twice.

Should you train abs while they're sore?
Go easy for a day or two. After a workout that leaves you very sore, a review of soreness research suggests cutting back how hard and how long you train for 1 to 2 days, or training other body parts while the sore ones recover (Cheung 2003). Everyday movement is fine; just skip hard ab work while they're sore (Cleveland Clinic).
| How sore? | What to do |
|---|---|
| Very sore | Walk, stretch, or train your legs or upper body instead |
| A little sore | Light core work, like a few easy planks, or another muscle group |
| Barely sore | Back to your normal ab workouts |
Soreness or injury?
| Sign | Normal soreness | Get it checked |
|---|---|---|
| How it feels | Dull, tender, stiff | Sharp or stabbing, or a pop when it started |
| Where | Spread across the muscle | One spot |
| With movement | Eases a little once you warm up | Gets worse |
| Swelling | None or a little | A lot |
| How long | Worst on days 2 and 3, mostly gone by day 5 | More than a week, or getting worse |
When to see a doctor
Get checked, or get care right away where it says so, if you notice any of these:
- Dark urine (brown, red or tea-colored) after a hard workout, especially with severe muscle pain, swelling or weakness. This can be rhabdomyolysis, a breakdown of muscle that can be life-threatening. Get medical care right away (Cleveland Clinic).
- A new bulge in your belly or groin, often one that shows up when you stand, cough or strain and goes back in at other times. It may be a hernia: see a doctor. If the bulge changes color, goes numb, or comes with fever, nausea or vomiting, get emergency care (Cleveland Clinic).
- Sharp pain in one spot, or a pop during the workout. It may be a muscle strain. See a doctor or physical therapist.
- Pain deep in your belly, or pain with fever, nausea or vomiting, that doesn't feel like a sore muscle. That isn't workout soreness: get checked.
- Severe swelling, sharp pain that doesn't let up, or soreness that lasts more than a week (Cleveland Clinic).
How to be less sore next time
- Build up over the first week or two of a new program: fewer rounds and the easier options first, then add more. A review of soreness research recommends bringing in new exercises gradually over 1 to 2 weeks (Cheung 2003).
- Repeat workouts. The second time through the same workout usually leaves you much less sore.
- Train abs regularly, a few short sessions a week rather than one big one after a long break. Our 5 minute ab workouts are an easy way to start.
Questions
How long do sore abs last?
Usually a few days. Soreness tends to start within a day or two, peak 2 to 3 days after the workout and fade within about 5 days. If it lasts more than a week, see a doctor.
How long do abs take to recover after a workout?
About 48 hours after a hard ab workout, so leave a day between hard sessions. Light core work in between is fine. If your abs are still very sore, give them another day.
Do sore abs mean my workout worked?
Not necessarily. Soreness mostly means the workout was new, harder than usual, or had a lot of slow lowering. You get less sore as your body gets used to a workout, even though it's still doing its job.
Why are only my lower abs sore?
Probably because the workout had a lot of leg raises, reverse crunches or flutter kicks. Those work the lower part of your abs and your hip flexors (the muscles at the front of your hips), so soreness often shows up low on your belly or at the front of your hips. Sharp pain in one spot, or a bulge in your groin, is different: see a doctor.
Should I work out with sore abs?
Yes, but go easy on your abs. Walk, stretch or train other muscle groups, and save hard ab work for when the worst has passed, usually after a day or two.
Can I do abs every day?
Light core work, yes. Hard ab workouts go better with a day off in between, and three or four a week is plenty for most people.
Is it OK to stretch sore abs?
Yes, gently. Go to a mild pull, never pain, and hold each stretch for 10 to 30 seconds. It may feel good, but research shows stretching does little to reduce soreness.
What are the best stretches for sore abs?
Gentle stretches for the front and sides of your core: a full body stretch on your back, cat cow, cobra, a kneeling side stretch for your obliques and a modified camel. Hold each for 10 to 30 seconds, 2 to 4 times. They won't make soreness go away faster, but they can help you feel looser.
Why does it hurt to laugh or cough?
Your abs tighten every time you laugh, cough or sneeze, so sore abs make all of them uncomfortable for a few days. That's normal. A sharp pain, or a bulge that appears when you cough, is not: see a doctor.
