15 Fat-Burning Flat Belly Workouts to Burn Calories Fast

In fact, belly fat is one of the most stubborn areas to lose fat from, especially as we age. But don’t worry—this isn’t about endless sit-ups or fancy gym equipment. The real secret? Combining high-intensity moves with core-focused workouts that burn calories fast while sculpting your midsection. 

So if you’re ready to ditch the belly bloat, shrink your waistline, and feel stronger all over, dive into these 15 powerhouse fat-burning workouts. They’re effective, efficient, and perfect for doing right at home—no gym required!

1. High-Intensity Interval Training (HIIT)

HIIT is like the secret sauce of fat-burning. It blends short bursts of all-out effort with quick recovery periods, keeping your heart rate elevated and your body in fat-burning mode long after you stop moving. The afterburn effect—technically called excess post-exercise oxygen consumption—means you continue to burn calories even at rest!

This makes HIIT perfect for belly fat reduction. The alternating movements engage your core, glutes, and cardiovascular system, forcing your body to use fat as fuel. Start with 30 seconds of jump squats, 15 seconds of rest, 30 seconds of burpees, then repeat for 15–20 minutes. Bonus? HIIT can be adapted to any fitness level and done with zero equipment—ideal for busy mornings or post-work energy bursts.

2. Plank to Push-Up (Moving Plank)

This movement is deceptive—it looks simple but burns deep. Transitioning from a forearm plank to a full push-up position activates your shoulders, arms, chest, and core in a slow and controlled way. It builds endurance while also tightening your abdominal muscles and improving posture. It’s especially great for core stability. Planks engage your entire trunk, and this dynamic version adds upper-body strengthening and calorie-burning movement. Add it into your routine for 3 sets of 10–12 reps. To maximize fat burning, keep your hips square and your transitions smooth. The more controlled you are, the more muscles you recruit.

3. Russian Twists with a Medicine Ball

Say hello to your obliques! Russian twists target the sides of your abs—the muscles that cinch your waist and give you that sculpted look. Using a medicine ball (or even a heavy book!) adds resistance and boosts calorie burn. Sit with your knees bent and lean slightly back, holding the weight close to your chest. Twist side to side, tapping the ball on the floor with each rotation. Your core should do the work, not your arms. To level up, lift your feet off the ground for extra intensity. Try for 3 sets of 20 twists (10 per side). This is a core killer in the best way.

4. Bicycle Crunches

Old school? Maybe. Effective? Absolutely. Bicycle crunches are one of the most efficient ab workouts around. They work the rectus abdominis (front abs), obliques (side abs), and even the lower belly in one fluid motion. Lie on your back, hands behind your head. Bring your knees toward your chest and alternate touching opposite elbow to knee in a pedaling motion. Not only does this spike your heart rate, but it also forces core engagement and coordination.Do 3 sets of 30 seconds and feel your abs light up. Keep the movement slow and controlled to avoid cheating with momentum.

5. Jumping Jacks with a Twist

This upgrade to a childhood classic gets your heart pumping and your core involved. As you jump your feet in and out, add a torso twist with your arms—reaching one hand across your body while twisting through your waist. This added movement makes jumping jacks more than just cardio—it turns them into a fat-burning, belly-toning hybrid. Plus, it’s fun and easy to fit into warm-ups or circuit training. Keep the pace high for 1-minute intervals and repeat 3 times. You’ll be breathless and burning belly fat in no time!

6. Mountain Climbers

Think of mountain climbers as the ultimate two-for-one: cardio + core. This bodyweight move elevates your heart rate while targeting your lower abs, upper body, and glutes. Start in a high plank position and drive your knees toward your chest, alternating quickly. The movement mimics climbing, and when done at speed, it torches calories rapidly. Do 30 seconds on, 15 seconds off, and repeat 4–5 times. For even more burn, try cross-body climbers to hit the obliques too.

7. Flutter Kicks

Need a killer lower ab workout? Flutter kicks are your answer. Lie on your back, hands under your glutes, and lift your legs off the ground. Alternate fluttering them up and down in a small, quick motion. They look simple, but within seconds, you’ll feel the burn deep in your lower core. They’re excellent for reducing lower belly pooch and toning the hips and thighs at the same time. Aim for 3 sets of 20–30 seconds, resting briefly in between. Keep your lower back pressed into the mat for safety.

8. Standing Oblique Crunches

No mat? No problem. Standing oblique crunches are a great no-floor option that’s easy to fit into quick routines or daily movement breaks. Plus, they’re friendly on the knees and back. Sand tall, bring your right knee toward your right elbow while crunching sideways, then alternate. Keep your core tight throughout for max impact. This is ideal for beginners or anyone needing a low-impact core solution. Do 3 sets of 15 reps per side. You’ll sculpt your waist while improving balance and posture.

9. Burpees with a Core Jump

Burpees are already a full-body powerhouse—but add a jump and core twist at the top and you’ve got yourself a fat-torching monster. Start in a standing position, drop to a squat, kick your feet back into a plank, jump back in, then explode upward with a twist. This high-intensity move burns massive calories while activating your core, legs, and upper body. It’s the epitome of a belly fat-busting exercise. Try 3 sets of 10–12. Yes, they’re tough—but so worth it.

10. Kettlebell Swings

This explosive, dynamic movement is perfect for total-body engagement. The swinging motion comes from your hips and core—not your arms—making it one of the most powerful ways to sculpt abs while burning fat. Start with a light kettlebell (or even a dumbbell) and hinge at your hips, thrusting forward to create momentum. Your abs should stay braced the entire time to prevent lower back strain. Do 3 sets of 15–20 swings. You’ll not only burn calories but also build real functional strength.

11. V-Ups

V-ups are advanced—and they hit the entire core hard. Lie on your back, arms overhead. Simultaneously lift your legs and upper body into a “V” shape, reaching your hands toward your toes. This movement requires flexibility, coordination, and serious core strength. Start slow and focus on form rather than speed. Do 3 sets of 10–12 reps. They’re tough, but with practice, you’ll see amazing definition in your midsection.

12. Skater Hops

Skater hops aren’t just for cardio—they sculpt your obliques and lower abs through lateral movement. Start by hopping side to side like a speed skater, tapping your back foot lightly behind you. This movement builds stability, coordination, and cardiovascular endurance—all while targeting the waistline. Do 3 sets of 30 seconds, resting in between. Try to land softly and stay low for the best results.

13. Side Plank Hip Lifts

Want to target the love handles directly? Side plank hip lifts are your go-to. Get into a side plank on your elbow and lower your hips toward the ground, then lift back up. This small but intense movement isolates the obliques and improves balance and spinal stability. Do 12–15 reps on each side for 3 rounds. If it’s too tough, keep the bottom knee bent for support. Your waistline will thank you.

14. Reverse Crunches

Reverse crunches offer a gentler, spine-friendly alternative to traditional crunches. Lie on your back, lift your legs, and use your lower abs to pull your hips off the floor. This movement is excellent for reducing lower belly bulge and toning the core without straining the neck or back. Do 3 sets of 15 reps, focusing on controlled, smooth movements. It’s all about form, not speed.

15. Jump Rope Intervals

Jumping rope isn’t just for kids—it’s a killer cardio workout that scorches calories while engaging your core, calves, and shoulders. Adding it into your routine boosts endurance and burns belly fat fast. Do intervals: 1 minute jumping, 30 seconds rest. Repeat 4–5 times. Bonus points if you add crossovers or double-unders! It’s portable, fun, and surprisingly challenging—a great way to mix things up.
