Ab Workouts: Free Guided Routines for Every Fitness Level

Pick four things: level (beginner, intermediate, advanced), time (5, 10, 15 or 20 minutes), equipment (none, a dumbbell, or a gym) and the zone you want to focus on (all, upper, lower, obliques, core). The session changes every day, the timer keeps running if you switch tabs, and each exercise has an easier and a harder version one tap away. No account, no email.

What a complete ab workout trains

Your “abs” are four muscle groups with different jobs, and a workout that only does crunches trains one of them. The table shows what each group does and which moves from our library load it most.

A balanced ab workout includes at least one move that bends the trunk, one that rotates or side-bends it, and one that holds it still. With “all zones” selected, the generator draws from all four groups.

How often should you do ab workouts?

Two to three ab workouts a week is enough for most people. The CDC asks adults for at least 2 days a week of muscle-strengthening activity that works all major muscle groups, and it lists the abdomen among them, next to 150 minutes of moderate activity such as brisk walking (CDC, page dated December 20, 2023).

You can train abs on back-to-back days if the sessions are short and nothing hurts. Most of the progress comes from doing the work every week for months, so pick a schedule you can keep.

Three ready-made ab workouts

Each workout below is a circuit: do every exercise in order, rest for the time shown, then repeat the round. Start with the level that feels slightly too easy. If you finish with good form and no back pain, move up next week.

Beginner ab workout (10 minutes, no equipment)

Two rounds. Work 30 seconds, rest 30 seconds.

Intermediate ab workout (15 minutes, no equipment)

One minute of warm-up (march in place, slow trunk rotations), then two rounds. Work 40 seconds, rest 20 seconds.

Advanced ab workout (20 minutes, no equipment)

Two minutes of warm-up, two rounds, then two minutes of easy stretching. Work 45 seconds, rest 15 seconds. Drop to the easier version (in brackets) as soon as your lower back lifts off the floor.

These three sessions are starting points. The generator above builds a new one each day from 45 animated exercises, so your workout doesn’t turn into the same routine every week.

Which ab exercises work best?

The bicycle crunch and the captain’s chair knee raise came out on top in the best-known test of ab exercises. In 2001, researchers at San Diego State University measured muscle activity (EMG) in 30 adults aged 20 to 45 doing 13 common exercises. The bicycle maneuver ranked first for the rectus abdominis, the captain’s chair ranked first for the obliques, and the traditional crunch came 11th of 13 (ACE press release, May 14, 2001).

A later test changes the picture for gadgets. In 2014, a University of Wisconsin-La Crosse study of 16 adults found that none of 8 ab devices and 7 bodyweight moves activated the abs more than a basic crunch. Front and side planks showed lower rectus activity than the crunch, and ACE’s chief science officer noted that planks still help build core stability (ACE press release, April 23, 2014).

Both studies are small and old, and EMG measures muscle activity, not visible results. The practical takeaway is simple: bodyweight moves you can do anywhere are as good as most equipment, and a mix of flexion, rotation and plank work covers what the studies measured. Our comparison of the best ab workouts puts these rankings in one table.

Why your abs may not show yet

Ab workouts make the muscles stronger, but they don’t remove the fat that covers them. In a 2011 randomized trial, 24 sedentary adults did 7 ab exercises (2 sets of 10) five days a week for six weeks. They got stronger at curl-ups, but their belly fat, body fat percentage and waist size did not change significantly compared with the control group (Vispute et al., J Strength Cond Res, 2011).

Visible abs need two things at once: muscles that are trained, and a low enough level of body fat over them. Losing fat comes mostly from eating and overall activity. The CDC suggests a steady pace of about 1 to 2 pounds a week for people who want to lose weight (CDC, page dated January 17, 2025). If you want a realistic timeline, our guide on how to get abs fast does the math.

The quickest way to see where you stand is to measure it. Our scan reads one photo and gives you a score out of 100, four sub-scores (visibility, symmetry, lower belly, obliques), a body-fat range and your weakest zone. The first scan is free and complete, with no card required.

How to make your ab workouts harder over time

Your abs adapt like any other muscle, so the same 10 minutes will stop working after a few weeks. Change one thing at a time:

1. Add time: go from 30 to 40, then 45 seconds of work.
2. Cut rest: from 30 to 20, then 15 seconds.
3. Add a round, or move from 10 to 15 or 20 minutes.
4. Switch to the harder version of one exercise (crunch to sit-up, plank to plank shoulder tap, reverse crunch to leg raise).
5. Add a load once bodyweight feels easy: a dumbbell crunch or a weighted Russian twist (see the dumbbell ab workout).

Common ab workout mistakes

• Pulling on your neck during crunches. Keep your hands light behind your head, or cross them on your chest.
• Arching the lower back during leg raises and flutter kicks. If your back lifts, bend your knees or switch to the dead bug.
• Holding your breath. Breathe out as you curl up or lift your legs.
• Rushing reps. Keep a controlled pace so momentum does not do the work for you.
• Only training the front. Add side planks and rotation work for the obliques.

Ab workouts by goal

Every page below answers one specific question and opens the same free generator, preset for that goal.

Free and paid: what you get

The daily session, the first full scan and a 7-day routine are free, with no account and no card. The paid program is for people who want to be followed over time: an 8 to 12 week plan in three phases that adapts to your weekly scan, before-and-after photos lined up automatically, and missed days that shift the plan instead of breaking it. Prices are shown upfront, in your currency, and there is a one-time option.

Workout and first scan free. Full program: $28.99, paid once. Pricing

Safety

This page is general fitness information, not medical advice. Stop any exercise that causes sharp pain, and talk to a doctor or physical therapist before training if you have a back injury, a hernia, a heart condition, or if you are pregnant or have recently given birth. Our workouts are not designed for pregnancy or postpartum recovery.

Frequently asked questions

Do ab workouts burn belly fat?

In a 2011 randomised trial, 24 adults did 7 ab exercises five days a week for six weeks. They got stronger, but their abdominal fat, fat mass and waist did not fall significantly against the control group (Vispute et al., 2011). Belly fat falls with overall fat loss, so abs are one part of the plan.

How many ab workouts a week?

Two to three sessions fit the guidelines: the CDC and NHS ask for strengthening on at least two days a week, including the abdomen. Our plans leave rest days between sessions.

How long should an ab workout be?

The free generator builds sessions of 5, 10, 15 or 20 minutes. Beginners get 30 seconds of work and 30 of rest, intermediates 40 and 20, advanced 45 and 15. Pick a length you can repeat every week.

Are ab workouts effective?

They make the muscles stronger, as the 2011 trial above shows. Whether your abs are visible depends mostly on body fat, which the free photo scan can estimate as a range.
