Why 3 Weeks is the Perfect Time Frame for Belly Fat Loss
Losing belly fat isn’t an overnight process, but with dedication, consistency, and the right routine, three weeks is a realistic timeframe to see real results. The combination of full-body exercises, core strengthening moves, and fat-burning cardio in this routine will activate your metabolism, help you burn calories, and reduce fat all over your body—including your belly. By sticking to this challenge every day, you can expect tighter abs, increased core strength, and a noticeable reduction in belly fat.

1. 9-Minute Plank: Build Core Strength
The plank is one of the most effective core exercises you can do. It targets not only the abs but also the back, shoulders, and glutes, making it a full-body workout. Holding the plank position for extended periods helps increase endurance and engage the core muscles, which is essential for a flat stomach.
- How to Do It:
- Start in a push-up position with your forearms on the ground and your body in a straight line from head to heels.
- Engage your core, squeeze your glutes, and keep your shoulders, hips, and ankles aligned.
- Hold the position for 9 minutes, taking short breaks if necessary.
Tip: Focus on keeping your body straight and avoid letting your hips sag. This will prevent unnecessary strain on your lower back.
2. 5-Minute Bridge Pose: Activate Your Glutes and Core
The bridge pose not only strengthens the glutes but also works the lower back and core. This is a great move for building a strong foundation, helping to create a flat belly by strengthening the muscles that support your abdomen.
- How to Do It:
- Lie on your back with your knees bent and feet flat on the floor, hip-width apart.
- Place your arms by your sides for support.
- Lift your hips off the ground, squeezing your glutes and engaging your core as you raise your body into a bridge position.
- Hold the pose for 5 minutes.
Tip: Make sure your knees don’t extend beyond your toes and focus on pushing through your heels to lift your hips.

3. 45-Degree Elbow to Knee Crunches: Target the Obliques
This exercise is perfect for targeting your obliques, the muscles along the sides of your torso. By engaging both the upper and lower abs, this move will help you achieve a more defined waistline while also promoting fat loss around the belly area.
- How to Do It:
- Lie on your back with your knees bent and feet flat on the floor.
- Place your hands behind your head and lift your shoulders off the floor.
- Bring your right elbow to your left knee, while straightening your right leg.
- Switch sides and repeat for a total of 45 elbow-to-knee crunches.
Tip: Keep your elbows wide and avoid pulling on your neck with your hands. Focus on using your core to initiate the movement.
4. 90 Squats: Tone Your Legs and Core
Squats are a full-body exercise that primarily targets the lower body but also engages the core. When done correctly, squats activate your abdominal muscles to maintain balance, which helps tone the belly while also strengthening the legs and glutes.
- How to Do It:
- Stand with your feet shoulder-width apart and your back straight.
- Lower your body by bending your knees, keeping your knees behind your toes.
- Go as low as you can, aiming to get your thighs parallel to the ground.
- Push through your heels to return to standing and repeat for 90 squats.
Tip: Focus on maintaining good form throughout the movement. Engage your core as you squat down and rise back up.

5. 5-Minute High Knees: Boost Your Heart Rate
High knees are a great cardio exercise that helps get your heart pumping while also engaging your core. This move will not only help burn calories but also improve your stamina and endurance, making it an essential part of any fat-burning routine.
- How to Do It:
- Stand tall with your feet hip-width apart.
- Lift one knee as high as possible toward your chest, then quickly alternate legs, bringing the other knee up.
- Perform this move for 5 minutes, maintaining a brisk pace to keep your heart rate elevated.
Tip: Keep your core engaged and avoid leaning backward as you perform the exercise.
6. 60 Elbow to Knee Side: Target the Obliques and Lower Abs
Side elbow-to-knee crunches are excellent for sculpting the sides of your belly and strengthening the obliques. This move helps tone the side abs, reducing love handles and enhancing the overall appearance of your midsection.
- How to Do It:
- Lie on your back with your knees bent and feet flat on the floor.
- Place your hands behind your head and lift your shoulders off the floor.
- Bring your right elbow toward your left knee while extending your right leg out straight.
- Switch sides and repeat for a total of 60 elbow-to-knee side crunches.
Tip: Keep your shoulders lifted off the floor and focus on twisting through your torso to engage your obliques.

7. 100 Crunches: Build Upper and Lower Abs
Crunches are a classic abdominal exercise that targets both the upper and lower abs. They’re effective for strengthening the core and improving overall abdominal tone. While they won’t specifically burn belly fat, they help build the muscle definition that gives your midsection a toned, sculpted look.
- How to Do It:
- Lie flat on your back with your knees bent and feet flat on the floor.
- Place your hands behind your head or cross them over your chest.
- Lift your upper body toward your knees, engaging your abs to raise your torso.
- Lower back down slowly and repeat for 100 crunches.
Tip: Focus on using your abs to lift your torso, not your neck. Avoid pulling on your head with your hands.
