7 Effective Flat Belly Workouts to Lose Belly Fat (2025 Guide)

Let’s dive into the belly-fat-burning zone—get ready to sweat, sculpt, and transform your core in 2025!

1. Plank Variations

Planks are a timeless core workout—and for good reason. They engage not just your abs, but your shoulders, glutes, and back as well. This multi-muscle engagement helps burn more calories and tighten your core. Start with the standard forearm plank, keeping your back straight and abs tight. You should feel tension from your shoulders down to your toes. To spice things up, try plank with shoulder taps or plank leg lifts—these small movements keep your core under constant tension and test your stability.

Another powerful variant is the side plank, which activates your obliques and improves balance. Switch sides halfway through to ensure symmetrical strengthening. Holding each variation for 30–60 seconds will challenge your endurance and build a rock-solid core. Planks are often underrated but outperform traditional crunches in activating the deep abdominal muscles. For anyone serious about flattening their stomach, this is a foundational move.

2. Mountain Climbers

Mountain climbers blend cardio and core work into one high-intensity exercise. They’re ideal for raising your heart rate while targeting the belly area. The rapid knee-driving motion engages your abs while torching calories. Begin in a high plank position, hands aligned under your shoulders. Alternate driving your knees toward your chest as fast as possible. Maintain a flat back to avoid putting strain on your lower spine.

You can scale up the intensity by incorporating them into HIIT circuits, doing 40 seconds of climbers followed by 20 seconds of rest. Not only do mountain climbers target your abdominal muscles, but they also boost your metabolism long after the workout ends. To get the most from this move, focus on speed, form, and breathing. A few rounds a day can make a noticeable difference in your midsection over time.

3. Russian Twists

If you’re aiming to cinch your waistline, Russian twists are a go-to. They target your obliques—those side muscles that define the shape of your core. Sit on the floor, knees bent, feet lifted or resting gently on the ground. Lean back slightly, keeping your spine straight. Clasp your hands or hold a dumbbell, and twist your torso from side to side, tapping the floor beside your hips.

Perform 20 reps per side, maintaining a controlled pace. You’ll feel the burn quickly, especially with added resistance. If you want to advance the move, lift your feet off the ground for more core activation. Keep in mind: it’s easy to swing the arms and lose form. Focus on rotating your torso to ensure you’re working the right muscles. This movement is key for anyone looking to reduce love handles and gain core definition.

4. Leg Raises

Leg raises are one of the best exercises for targeting lower belly fat, an area that’s notoriously tough to tone. They strengthen the lower abdominals and help flatten the stomach. Lie on your back, hands under your glutes for support. Keep your legs straight and raise them toward the ceiling, then slowly lower them back down without touching the floor. This slow, controlled descent is where the magic happens—it forces your core to stay engaged.

If you experience back pain, try reverse leg raises or bend your knees slightly. You can also use resistance bands or ankle weights to increase the challenge. For gym-goers, hanging leg raises on a pull-up bar take things to the next level. Incorporate 3 sets of 10–15 reps into your routine. Over time, you’ll notice better core control and a tighter midsection.

5. Burpees

Burpees may not be anyone’s favorite, but they’re incredibly effective. This full-body exercise increases your heart rate, burns fat, and builds strength—especially in the core. Start in a standing position, drop into a squat, kick your feet back into a plank, do a push-up, return to the squat position, and leap into the air. That’s one rep. Aim for 8–12 reps per set.

Burpees are a high-intensity movement, ideal for total-body fat loss. For those with joint concerns or beginners, try low-impact burpees—eliminate the jump and move at a slower pace. Add burpees to your HIIT sessions or do a few rounds solo for a quick calorie burn. They’re hard, yes, but few moves match their efficiency when it comes to burning belly fat fast.

6. Bicycle Crunches

Bicycle crunches are a core-blasting exercise that works your upper abs, lower abs, and obliques in one smooth motion. They mimic a pedaling action while engaging your entire abdominal region. Lie flat on your back, place your hands behind your head, and lift your legs off the ground. Alternate bringing your elbow to the opposite knee while fully extending the other leg. Continue the motion like you’re pedaling a bicycle.

Focus on controlled movements and breathing. It’s easy to rush through the reps, but slower execution ensures deeper muscle engagement. Avoid pulling on your neck—let your abs do the work. Try three sets of 15–20 reps. Over time, this exercise can contribute significantly to trimming your waist and toning your belly.

7. Seated Knee Tucks

Perfect for small spaces and quick routines, seated knee tucks target the lower belly and improve balance and posture. This is a gentle yet potent move, great for desk workers or those short on time. Sit on a mat or bench, place your hands behind you for support, and extend your legs out. Pull your knees into your chest, then push them back out without letting them touch the ground. Keep your core braced throughout the movement.

For added difficulty, hold a dumbbell between your feet or perform the move on a decline bench. Aim for 3 sets of 12–15 reps. Even without added weight, this move strengthens the lower abdominal wall and contributes to a flatter tummy. It’s a great way to end a workout session, combining balance, control, and burn all in one.
