1. Standing Oblique Crunches

Standing oblique crunches are a lifesaver when you don’t have time to hit the floor. This simple movement targets your waistline and love handles while also improving balance.

• Stand tall with your hands behind your head.
• Raise your right knee toward your right elbow while bringing your elbow down to meet it.
• Return to start and switch sides.

Do 15 reps per side for 3 sets. The beauty of this workout is its flexibility—you can do it in your kitchen while waiting for your coffee or while catching up on your favorite show. It strengthens your core, improves posture, and doesn’t require any special gear. Plus, standing oblique crunches help reduce side belly fat, making them perfect for achieving that slim waist look. You’ll feel the burn in no time!

2. Bicycle Crunches

Bicycle crunches are one of the most effective moves for targeting both the upper and lower abs. They engage the obliques, which helps define the waist and flatten the belly.

• Lie on your back and lift your legs to a tabletop position.
• Place your hands behind your head and bring your right elbow toward your left knee while straightening the right leg.
• Alternate sides in a pedaling motion.

Do 20 reps (10 per side) for 3 rounds. Keep the pace controlled for maximum core activation. These crunches also boost coordination and work multiple abdominal muscles at once, making them highly efficient for busy women. Best part? You can do them anywhere with just a yoga mat. No equipment. No excuses.

3. Plank with Shoulder Taps

The plank is already a go-to for core strengthening, but adding shoulder taps takes it to another level. It builds stability and targets your entire abdominal region.

• Start in a high plank position with shoulders over wrists.
• Tap your left shoulder with your right hand, then return to plank.
• Tap your right shoulder with your left hand.

Complete 20 taps (10 per side) for 3 sets. This movement works your core, glutes, and shoulders. It also enhances balance and coordination. Plank shoulder taps are quick and effective—ideal for anyone short on time. You can even turn this into a mini circuit with other exercises on the list for a full ab session in under 15 minutes.

4. Seated Knee Tucks

No space? No problem. Seated knee tucks can be done at your desk, on a couch, or any sturdy chair. They help strengthen deep core muscles and improve posture.

• Sit on the edge of a chair, lean back slightly.
• Hold onto the sides for balance.
• Bring your knees toward your chest, then extend your legs.

Repeat for 15 reps and aim for 3 rounds. This workout is excellent during work breaks and lunch hours. It doesn’t break a sweat but works your abs hard. With consistent practice, seated knee tucks contribute to a flatter tummy and firmer core without the hassle of floor exercises.

5. Reverse Crunches

Reverse crunches are especially effective at targeting lower belly fat—a stubborn area for many women. They’re gentle on the spine and safe for beginners.

• Lie flat on your back with legs bent and feet off the floor.
• Lift your hips off the mat as you curl your knees toward your chest.
• Slowly return to the starting position.

Do 15 controlled reps for 3 sets. Avoid using momentum and focus on engaging your abs. This movement is simple but powerful. Done regularly, it helps shrink the lower tummy and improve muscle tone. It’s also a great transition workout between more intense movements.

6. High Knees

High knees are a fantastic way to combine cardio with core training. They elevate your heart rate, torch calories, and target the abdominal area all at once.

• Stand tall and run in place, lifting your knees as high as possible.
• Swing your arms to increase intensity.

Do 30 seconds on, 15 seconds rest, repeat for 3 rounds. They fit perfectly into a morning routine or pre-shower blast. High knees are energizing, making them a go-to when you need a quick belly-fat-blasting boost. They also improve leg strength and stamina over time.

7. Mountain Climbers

Fast-paced and fiery, mountain climbers target the abs while providing a solid cardio burn. They’re great for building endurance and engaging the entire core.

• Begin in a plank position.
• Drive one knee toward your chest, then switch legs quickly.

Perform for 30 seconds, rest, and repeat 3 times. Keep your core tight and body in a straight line throughout. Mountain climbers don’t just work your abs—they activate shoulders, arms, and legs. It’s a full-body move that delivers results quickly.

8. Flutter Kicks

Flutter kicks help tone the lower abs and increase core endurance. They may look easy, but the burn builds fast!

• Lie on your back and place your hands under your glutes.
• Raise your legs slightly off the ground.
• Alternate kicking your legs up and down.

Do this for 30 seconds per set, resting between each round. Aim for 3 rounds. Focus on controlled, small movements rather than speed. Flutter kicks are perfect for adding variety to your routine and tackling stubborn belly fat with precision.

9. Side Plank Hold

Side planks target the obliques and build core stability, making them essential for a balanced midsection.

• Lie on your side with legs stacked.
• Lift your hips off the ground and support yourself on your forearm.
• Hold for 20–30 seconds per side.

Repeat 2–3 rounds per side. You can increase hold time as you progress. This static move enhances balance, posture, and tightens the side waist. It’s also gentle on the spine and joints.

10. Leg Raises

Leg raises are a classic ab move that’s perfect for firming up the lower tummy and improving overall core strength.

• Lie flat on your back with your legs extended.
• Slowly raise both legs to a 90-degree angle.
• Lower them without letting them touch the floor.

Do 10–15 reps for 3 sets. Concentrate on keeping your lower back pressed into the floor. Leg raises require no equipment and work well as a finisher to your ab workout. When done regularly, they deliver visible toning effects.
