25 Fat-Burning Flat Belly Workouts for a Toned Tummy

According to the Mayo Clinic, a combination of targeted core exercises and cardio is one of the most effective ways to lose belly fat and build muscle definition. But we’re not just here for the science. You want real results, right? That’s why we’ve compiled 25 of the most powerful ab and core workouts that can fit into any lifestyle, schedule, or fitness level.

Ready to tone up and feel amazing? Let’s dive into these body-sculpting, fat-blasting moves that’ll help you get that toned tummy—no crunches necessary (well, maybe just a few.!

1. Plank Variations for Total Core Activation

Planks are a gold standard in core workouts—and for good reason. They don’t just target your abs, they challenge your entire body to stabilize, engage, and hold. From your shoulders to your glutes, planks activate multiple muscle groups at once.

Start with the traditional forearm plank, holding your body straight like a board. Once you’ve mastered that, try side planks to hit the obliques or add dynamic movement like leg lifts to increase the intensity. Don’t forget to breathe deeply and keep your hips aligned. Holding for 30–60 seconds per round is ideal. Consistency is key. Try incorporating plank variations into your daily routine and notice how your core strength improves over time. These moves are the foundation of a stronger, leaner belly.

2. Bicycle Crunches

Bicycle crunches are an old-school favorite that still packs a punch. They work your upper and lower abs while also targeting your obliques, making them a fantastic full-core burner.

Lie on your back, lift your legs, and alternate bringing opposite knees and elbows together in a twisting motion. The key here? Go slow and controlled—don’t rush. That twist engages deep core muscles and helps shred away belly fat. Do 2–3 sets of 20–30 reps. This one is especially effective when combined with cardio days, helping to tighten your waistline and increase core endurance.

3. Russian Twists

This killer oblique move is all about balance and control. Sit on the floor with knees bent, lean back slightly, and rotate your torso side to side while holding a weight or medicine ball. Keep your spine long and your abs tight throughout. Want to turn up the burn? Try lifting your feet off the floor. You’ll feel the difference immediately. Russian twists are perfect for sculpting a slim waist and improving rotational strength, especially when added to circuit training or paired with HIIT.

4. Mountain Climbers

Fast, fierce, and incredibly effective—mountain climbers bring cardio and core together for a total-body blast. Begin in plank position and drive your knees toward your chest rapidly, one at a time. What makes this move so powerful is its ability to spike your heart rate while working your abs. In just 30–60 seconds, you’ll feel the burn—and you’ll be burning belly fat, too. Include mountain climbers in between strength moves to maximize fat loss and endurance.

5. Leg Raises

If you struggle with lower belly pooch, leg raises are your go-to move. Lie flat on your back with your hands by your sides or under your hips. Slowly lift your legs to a 90-degree angle and lower them back down without touching the floor. This exercise targets the lower abdominal region, which is often hard to reach with traditional crunches. Keep your core tight and avoid arching your back. Try 3 sets of 10–15 reps to start building strength in your lower core.

6. Flutter Kicks

Flutter kicks may look easy, but they’re deceptively tough—and effective. Lying on your back, lift your legs slightly and kick them up and down in a fluttering motion. This targets lower abs, hip flexors, and improves core stability. It’s a great fat-burning move, especially when done for 30–60 seconds per round. You can add it to your warm-up or use it to finish off a workout with a final burn.

7. Reverse Crunches

Tired of traditional crunches? Try this game-changer. Reverse crunches take pressure off your neck and focus entirely on your lower abs. Lie down, bend your knees, and bring them toward your chest, curling your hips off the ground. The key is control—avoid using momentum. Add them to your core days to help eliminate lower belly fat and build deep abdominal strength.

8. Dead Bug Exercise

This strangely named move is incredibly effective for core stabilization. Lie on your back with arms and legs in the air. Slowly lower opposite arm and leg while keeping your core engaged, then switch sides. The dead bug builds functional strength and coordination while protecting your lower back. It’s beginner-friendly, but even pros find it challenging when done right. Do 10 reps per side for 2–3 sets.

9. Standing Oblique Crunches

You don’t have to hit the floor to work your core. Standing oblique crunches are excellent for targeting the sides of your abs and improving posture. Stand tall, place your hands behind your head, and crunch sideways toward your knee. Keep your core tight and avoid leaning forward or back. These are great during warm-ups, cooldowns, or anytime you want a quick waistline toner.

10. V-Ups

Looking to challenge both your upper and lower abs? V-ups are your move. Lie flat, then simultaneously lift your arms and legs to meet in a “V” shape. This full-body ab burner requires flexibility, strength, and control. It’s advanced—but totally worth it. Aim for 10–15 reps for 3 sets. Feel the burn? That’s progress!

11. High Knees

One of the best cardio + core combos out there, high knees help you burn calories fast while engaging the lower abs. Stand tall and jog in place, bringing your knees up toward your chest at a rapid pace. Add arm movements for even more calorie burn. Use this as a cardio burst between strength sets or in a warm-up. Go for 30–60 seconds per round.

12. Toe Touches

Toe touches are simple yet super effective for working the upper abdominal muscles. Lie on your back, lift your legs straight up, and reach for your toes with your hands. This movement builds strength and flexibility and can be intensified with a small weight. Do 15–20 reps for a solid core burn.

13. Side Plank Hip Lifts

Take your planks to the next level with this variation that targets obliques and stabilizers. Start in a side plank and lower your hips down, then lift back up. This builds balance, endurance, and that coveted V-cut. Keep your body straight and controlled. Try 10–15 reps per side.

14. Heel Taps

Lie on your back with knees bent and feet flat. Reach side to side to tap each heel. This isolates the side abs and adds a nice sculpting touch to your midsection. Go slow and focus on tension. Do 30 taps (15 per side) for 3 rounds.

15. Seated Knee Tucks

Sit on a bench or floor with hands behind you for balance. Bring knees into your chest and extend out again. This move works your entire core, especially the lower abs, and can be done as a burnout set at the end of your workout. 3 sets of 10–15 reps will get your tummy working hard.

16. Jumping Jacks with Core Focus

A twist on a classic. Instead of flailing your arms and legs, focus on tightening your core while you jump. This boosts your metabolism and warms up your entire body. Add a few sets before your main ab routine. Aim for 1-minute intervals.

17. Standing Knee-to-Elbow

Lift one knee and bring the opposite elbow toward it while standing. This low-impact move is great for core coordination and can be used for active recovery days. Try alternating for 30 reps total.

18. Bear Crawls

Start in a tabletop position and crawl forward and backward with your knees off the floor. Bear crawls engage entire core muscles while improving shoulder and hip stability. They’re intense—but oh so worth it. Do 3 rounds of 20–30 seconds.

19. Lying Windshield Wipers

Lie flat, arms out to the sides, and legs lifted. Slowly lower your legs side-to-side like windshield wipers. This rotational movement sculpts the obliques and improves mobility. Keep your abs tight throughout. 10 reps per side is plenty!

20. Superman Holds

Lie face down and lift your arms, chest, and legs off the ground. This strengthens the lower back, an essential component of a strong core. Hold for 20–30 seconds and repeat 3 times.

21. L-Sits

This one’s a challenge! Sit between two blocks or on the floor and lift your legs straight out while holding yourself up. L-sits require serious strength and help build core endurance. Hold for 10–20 seconds if you can.

22. Weighted Sit-Ups

Classic sit-ups but with added resistance. Hold a dumbbell or medicine ball against your chest to make each rep harder. Keep your core engaged and avoid using momentum. Go for 15 reps for 3 sets.

23. Core Twists with Resistance Band

Anchor a resistance band at chest height, twist your torso away from the anchor point. This strengthens your rotational core and tones your sides. Do 10 reps each side for 2–3 sets.

24. Box Jumps with Core Engagement

Jump onto a sturdy surface and land softly while keeping your abs tight. This explosive movement boosts heart rate and builds total-body strength. Start with low boxes until comfortable.

25. Burpees

Everyone’s favorite (or least favorite. Burpees work your whole body and torch calories while giving your abs an intense challenge. They’re the perfect move to finish your workout strong. Try 10–15 reps for max burn.
