In this guide, we’re diving into 15 powerful flat belly workouts specifically designed to help you lose belly fat and sculpt a toned core. No fluff, no filler—just real, effective exercises you can start doing today. Let’s jump in and get that core fired up!

1. Bicycle Crunches

Bicycle crunches are a dynamic movement that targets both the upper and lower abs, while also engaging the obliques for a well-rounded core burn. This movement mimics a pedaling motion, making it a two-in-one fat-blasting and muscle-toning exercise.

Start by lying flat on your back, hands behind your head, and legs lifted with knees bent. As you bring your right elbow toward your left knee, extend your right leg straight out. Alternate sides in a smooth, controlled motion. The key? Slow and steady—not speed. Focus on form and really twist through the torso. Doing 3 sets of 15–20 reps per side can torch calories and deeply activate your abs. Over time, this movement helps reduce stubborn belly fat and improves muscle definition in your midsection.

2. Plank Hold

Planks are the cornerstone of core workouts. While they may look simple, holding a plank engages multiple muscle groups, especially the transverse abdominis, which acts like a corset for your midsection. Begin in a forearm plank position with elbows under shoulders and body in a straight line from head to heels. Keep your core tight, glutes squeezed, and avoid sagging in the hips. Start with 30 seconds and gradually work your way up to 1–2 minutes. Planking daily not only flattens your belly but also improves posture, reduces lower back pain, and builds endurance across your entire core. It’s an efficient, no-equipment move that works wonders.

3. Russian Twists

Russian twists are perfect for hitting those love handles and sculpting the obliques. This twisting motion engages the entire abdominal region, making it a go-to for a tighter waistline. Sit on the floor with knees bent and heels slightly lifted off the ground. Lean back slightly while keeping the spine straight, and clasp your hands together or hold a light weight. Twist your torso from side to side, tapping the floor beside your hips each time.

Do 3 sets of 20 reps (10 per side) with control. You can increase intensity by holding a dumbbell or medicine ball. This move not only burns belly fat but also builds rotational core strength, which is key for athletic movements.

4. Mountain Climbers

Want to torch belly fat fast? Mountain climbers combine cardio and core work for a high-intensity move that boosts your metabolism. Start in a high plank position and bring one knee toward your chest, then quickly switch legs as if running in place. Keep your core tight and back flat throughout. Go for 30–45 seconds for 3–4 rounds. This move is great for burning calories, building endurance, and activating your lower abs. It also improves cardiovascular health and overall coordination—perfect for a total body challenge.

5. Reverse Crunches

If you struggle with lower belly fat, reverse crunches are a must. Unlike traditional crunches, these focus directly on the lower abs without straining your neck or back. Lie flat on your back with hands by your sides and legs raised, knees bent at 90 degrees. Contract your abs to lift your hips off the floor, curling your knees toward your chest. Lower back down slowly. 3 sets of 15–20 reps can help build lower abdominal strength and flatten the belly. This low-impact move is great for beginners and easy to incorporate into any ab routine.

6. Leg Raises

Leg raises are excellent for isolating and strengthening the lower abdominals. They also work your hip flexors and improve core control. Lie on your back with your legs extended. Place your hands under your glutes for support. Slowly lift your legs until they form a 90-degree angle with your torso, then lower them back down without touching the floor. Perform 3 sets of 12–15 reps. Keep your movements slow and avoid using momentum. The controlled motion increases tension in your core and helps trim down that belly.

7. Flutter Kicks

Looking for a quick ab burner? Flutter kicks are a rapid-fire move that targets your lower abs and helps build endurance. Lie on your back with your hands under your hips and legs extended. Lift your legs a few inches off the floor and begin alternating kicks up and down. Keep your core tight and avoid arching your back. Go for 30–60 seconds per round, 3 rounds total. These kicks are perfect for finishing a workout and giving your lower abs that final burn.

8. V-Ups

V-ups are a full-core powerhouse. They hit your upper and lower abs simultaneously, making them ideal for advanced core training. Lie on your back with arms extended overhead. Simultaneously lift your legs and upper body, reaching your hands toward your feet to form a “V” shape. Lower with control. Try 3 sets of 10–15 reps. This movement requires balance, coordination, and core strength, so start slow and focus on form. You’ll feel the burn in no time!

9. High Knees

This is more than just a cardio drill. High knees activate your core, get your heart pumping, and shred fat fast. Stand tall and jog in place, lifting your knees as high as possible. Pump your arms for added intensity. Perform this move in bursts: 30 seconds on, 15 seconds off, for 3–4 rounds. High knees are great for metabolic conditioning, fat loss, and increasing agility. They can be done anywhere and work well as a warm-up or cardio finisher.

10. Dead Bug

Dead bugs may look funny, but they’re amazing for building core stability, especially for beginners or those with lower back pain. Lie on your back with arms extended toward the ceiling and knees bent. Slowly lower your right arm and left leg toward the floor while keeping your back flat. Return to start and switch sides. Do 3 sets of 10–12 reps per side. This movement reinforces core control, coordination, and proper spinal alignment—all vital for long-term belly fat reduction.

11. Standing Side Crunches

Not a fan of floor exercises? Standing side crunches offer a great alternative that targets the obliques and gets your blood flowing. Stand with feet hip-width apart. Place your hands behind your head. Lift your right knee toward your right elbow while crunching to the side. Repeat on the opposite side. Aim for 3 sets of 15 reps per side. Add light dumbbells for more resistance. It’s a great way to train your core while standing, especially during quick routines or active rest periods.

12. Lying Leg Circles

A gentle but effective move, leg circles challenge your core’s stability and work your lower abs and hips. Lie on your back with legs extended. Lift your legs and draw circles in the air—small or large, your choice. Make sure to rotate both clockwise and counterclockwise. Complete 3 sets of 10–12 circles per direction. This move adds variety and challenges your core in a new way, helping avoid plateaus in your training.

13. Spiderman Plank

Add a dynamic twist to your standard plank with this variation that targets your obliques and increases mobility. Start in a high plank. Bring your right knee toward your right elbow, then return to start. Repeat on the left. Move with control to keep your core engaged. 3 sets of 10–12 reps per side is a good place to start. This movement enhances flexibility, strengthens your abs, and adds variety to your planking routine.

14. Scissor Kicks

Scissor kicks are an advanced lower-ab move that also challenges your endurance. Lie on your back with legs extended and hands under your glutes. Raise your legs and begin crisscrossing them over and under each other. Keep your core tight and back flat. Go for 30–45 seconds per round. Do 3–4 rounds. It’s a fantastic fat-burning finisher that leaves your abs on fire—in the best way.

15. Toe Touches

Toe touches zero in on the upper abs and are excellent for tightening the top of the core. Lie flat with legs raised straight up. Reach your fingers toward your toes, lifting your shoulder blades off the mat. Exhale on each crunch. 3 sets of 15–20 reps will do the trick. It’s a simple yet effective movement for building definition and wrapping up your ab routine.
