You’d love to get rid of that stubborn little belly, and you’ve always been told that doing abs is the way to go. Well, that might actually be a mistake! Here’s why crunches aren’t necessarily the best way to lose belly fat… And more importantly, plenty of sport-based alternatives to abs. Not to mention our tips for a flat stomach !
Sommaire
Ab workouts: a bad idea?
First things first — and this is important: doing abs has never actually reduced belly fat. The reasons are actually quite straightforward, once you think about it:
- Targeted muscle work on the abdominal muscles doesn’t necessarily trigger localised fat loss. Your body may very well draw its energy from elsewhere.
- Ab sessions and crunches aren’t really the most effective method for triggering lipolysis.
- Doing intense, repeated ab exercises risks overdeveloping the abdominal muscles — such as the rectus abdominis. These bulkier muscles can end up “pushing” against the abdominal wall, actually making the belly look more rounded.
You’ve got the picture: ab workouts are far from the best way to lose belly fat.
What are the best alternatives to abs for a flat stomach?
We’ve put a range of sports activities to the test to find the best flat-stomach alternatives.
Alternative no1: Core stabilisation (planks)

Rethink your fitness routine and swap crunches for core stabilisation exercises like the plank and its variations. Ventral stabilisation gently engages both superficial and deep abdominal muscles, as well as the iliopsoas — one of the hip flexors. This way, you avoid the risk of abdominal atrophy caused by crunches, while deeply toning your core. An effective flat-stomach fitness routine should combine cardio exercises, stretching postures (for example from yoga or Pilates) and core work. Need inspiration? Check out here or there.
Alternative no2: Jump rope

It was your playground staple back in the day… The jump rope, of course! Jump rope training is a wonderfully complete workout:
- It tones the entire body
- It helps burn calories fast
- It improves your endurance and, in turn, your muscular, cardiovascular and respiratory capacity
Fair enough — but is jump rope more effective than abs for losing belly fat? Absolutely! This type of training engages every muscle group:
- The upper body, since rotating the rope requires the arms, shoulders and chest to work.
- The lower body, since repeated jumps trigger muscular contractions in the calves.
- The core, because maintaining proper posture and balance requires you to engage your abs.
What’s more, 15 minutes of jump rope is equivalent to 30 minutes of running — perfect for sculpting a dream figure and a flat stomach you’ll love! One caveat: if you have venous fragility, the repeated impact of jumping may aggravate your condition.
Alternative no3: Interval running

And since we’re on the subject of running, it could well help you lose belly fat far more effectively than endless crunches! The best way to run for fat loss is interval training. What does that mean? It involves alternating between fast and slow running over short bursts, similar to HIIT. The best rhythm for beginners is 30/30 intervals: 2 to 3 sets of 30 seconds at a fast pace followed by 30 seconds of easy jogging, repeated 8 times. Add some stretches to your routine and you’re on your way to a firm, toned core! Running remains one of the best sports for slimming down, toning your body and clearing your head.
Alternative no4: Walking

And if running isn’t your thing, walking could actually help you lose belly fat! That said, we won’t mislead you: the occasional stroll will be less effective than regular ab sessions… To get a flat stomach, you’ll need to walk with purpose. Try power walking or Nordic walking:
- Power walking is an active, endurance-based walk. The pace is brisk, the speed fast (between 6 and 10 km/h), and the posture engages the whole body.
- Nordic walking, inspired by cross-country skiing, is a fast-paced walk performed with specially designed poles. It engages almost every muscle in the body.
Walking should also be regular and done in sessions of at least one hour. Our tip for losing belly fat: 2 to 3 power or Nordic walking sessions per week. Not only will you rediscover a flat stomach, but also beautifully toned legs, a healthy weight and a lifted mood!
Alternative no5: Swimming

If you’re more of a water sports enthusiast, swimming is one of the best sports for slimming down, reducing the appearance of cellulite… and toning your core. Moving through water makes your muscles work differently. Natural balance is challenged, the water’s resistance gently engages the muscles, and different strokes target different muscle groups. All of that? Yes! And for the abs, nothing beats backstroke: the position on your back combined with flutter kicks intensely works the rectus abdominis and transverse muscles, with no risk of injury. Plus, one hour of backstroke burns around 540 kcal! So forget the crunches, slip on your swimsuit and see the results for yourself!
Alternative no6: Yoga

Who would have thought that a zen practice could be more effective at reducing belly fat than an ab session? And yet, there’s no denying that yoga is highly effective for slimming the waist and achieving a firmer stomach. Why? Because it corrects poor posture. And our “natural” posture has a significant impact on how our stomach looks: too arched and the belly protrudes forward; too hunched and it loses tone. Regular yoga practice corrects these postural habits and works the entire core (stomach and waist). It also requires deep breathing that actively engages the belly. And as a bonus: it’s perfect for letting go and unwinding — ideal for leaving stress behind. And we all know that stress does nothing good for a firm stomach…
What else can complement your fitness routine to lose belly fat?
Found your ab-free sport of choice? Great! Now let’s optimise your results!
1- Eat well
To get rid of that stubborn belly, exercise is great — but pairing your efforts with a balanced diet makes all the difference!
- Focus on fibre : it offers multiple benefits. First, it’s filling, so you won’t need to overeat to feel satisfied. Second, it lowers the glycaemic index of certain foods, helping to reduce post-meal fat storage. And finally, it supports healthy digestion, helping to say goodbye to bloating and other discomforts.
- Avoid “bloating” foods : fizzy drinks, fried foods, processed meats and other ultra-processed foods are best avoided. Hard to digest and nutritionally poor, they’ll only make your stomach look more bloated.
- Eat protein: to maximise the results of your workouts (abs-free!) and fuel your abdominal muscle mass, lean proteins are your best friend. White meat, fish, soy-based products, legumes…Plant-based or animal, the choice is yours!
- Think pre- and probiotics: prebiotic foods help “feed” beneficial bacteria, while probiotic foods are rich in good bacteria themselves. Invite fresh fruit and vegetables, wholegrains and fermented foods (yogurt, kefir, sauerkraut, green olives, tofu and kombucha) to your plate.
- Eat slowly and chew thoroughly: eating too fast is a bad habit. You digest poorly (leading to heaviness and gas), you eat too much (it takes around 20 minutes for the brain to register fullness) and you store fat directly around the belly.
