Whether you’re chasing that toned tummy look or just want to move with more ease, this is your go-to blueprint. Ready to feel the burn? Let’s dive in!

1. Plank Hold

The classic plank is deceptively simple. This static move works your entire core, from your rectus abdominis to your transverse abdominis, as well as your shoulders, glutes, and back. It’s the ultimate bodyweight core exercise for a reason.

To perform it properly, get into a forearm plank position, keeping your body in a straight line from head to toe. Engage your abs and avoid letting your hips drop. Start with 30 seconds and build up over time. The key here isn’t duration—it’s quality. Controlled breathing and full engagement are what sculpt those deep abdominal muscles.

What’s great about planks is their adaptability. You can modify them for beginners by starting on your knees or intensify them with arm or leg lifts. The result? A more functional, powerful core that helps with everything from lifting groceries to standing taller.

2. Russian Twists

Want to carve out your obliques and build rotational strength? Russian twists are your friend. This twisting motion engages your entire abdominal wall and helps define the waistline.

Sit on the floor with your knees bent, feet slightly lifted, and lean back slightly. Hold a weight or just clasp your hands and twist from side to side. The secret to success? Controlled movement, not speed. Each twist should be deliberate, engaging your core fully.

This is one of those ab exercises that translates well into daily life. Rotational movements like this help with lifting, turning, and even better posture. Add this to your flat stomach workout circuit a few times a week for visible results.

3. Mountain Climbers

Need a workout that fires up your abs and gets your heart pumping? Mountain climbers combine core strength with cardiovascular intensity for a belly fat-blasting double whammy.

Start in a plank position and alternate driving your knees toward your chest in a running motion. The faster you go, the more fat you torch. But remember, form matters. Keep your hips down and core tight.

These are great to include in a HIIT core routine because they elevate your heart rate while targeting your lower abdominals and obliques. Just 30 seconds of fast-paced mountain climbers can be more effective than minutes of slow crunches.

4. Bicycle Crunches

Time and again, studies have shown bicycle crunches to be one of the most effective abdominal exercises, especially for targeting the upper and lower abs and obliques.

Lie on your back, hands behind your head, and bring opposite elbow to opposite knee in a pedaling motion. Go slowly to get the most muscle activation. The twist is key—it brings the obliques into play while the lifting of the legs targets the lower abs.

Doing 3 sets of 20 reps, slowly and with control, can significantly increase ab definition over time. It’s one of the best workouts for core strength that also improves coordination.

5. Dead Bug

Don’t let the name fool you—this movement is a staple in physical therapy and performance training for core stability. It’s fantastic for beginners and pros alike.

Lie on your back with arms and legs raised, knees bent at 90 degrees. Lower opposite arm and leg simultaneously, keeping your lower back pressed into the floor. Alternate sides.

This movement teaches you how to engage your core while moving your limbs—a fundamental skill that prevents injury and builds lasting strength. It’s subtle but incredibly effective for building functional abs.

6. Flutter Kicks

Want to target the lower abs and improve endurance at the same time? Flutter kicks do just that while also challenging your hip flexors.

Lie flat on your back, hands under your glutes, and lift your legs slightly off the ground. Alternate kicking them up and down in a fluttering motion. Keep your core braced and don’t let your lower back arch.

This move may burn, but that’s a good sign. Incorporate it into your daily ab routine or core circuit for best results.

7. Leg Raises

Leg raises are a tried-and-true exercise for toning the lower belly and building strength in your hip and pelvic regions. They’re simple but not easy—and that’s what makes them effective.

Lie on your back, legs straight, and raise them up to a 90-degree angle. Slowly lower without touching the ground. Keep your hands by your sides or under your hips for support.

This move is ideal for anyone struggling with lower belly fat. It not only strengthens your lower abdominals but also improves flexibility and control.

8. V-Ups

A true full-core move, V-ups engage your upper and lower abdominals at the same time. Plus, they work your hip flexors and challenge your balance.

Lie flat and lift both your arms and legs up to meet in a V-shape. The key is keeping everything controlled. Don’t rush it—slow and steady activates more muscle fibers.

V-ups are excellent for defining ab lines and improving overall core coordination. Even just 10 reps per set can create a serious burn.

9. Side Plank with Hip Dips

This variation of the traditional side plank is amazing for targeting the obliques and improving lateral stability.

From a side plank position, slowly lower your hips a few inches, then raise them back up. Repeat for 10–15 reps before switching sides. It might look simple, but it’s a serious burner.

This is one of those exercises for love handles that really works. It tightens the waistline and strengthens shoulder stabilizers at the same time.

10. Reverse Crunches

Unlike traditional crunches, reverse crunches target the lower abs without putting strain on your neck or upper spine.

Lie down with knees bent, feet off the floor. Lift your hips off the mat and curl your knees toward your chest. Focus on using your abs to initiate the movement.

This is a beginner-friendly move that offers huge results when done consistently. Try pairing it with flutter kicks for a flat belly home workout combo.

11. Standing Oblique Crunches

No floor? No problem. Standing oblique crunches are perfect when you need a quick, equipment-free option.

Stand with feet shoulder-width apart, lift one knee while bringing the same-side elbow down to meet it. Alternate sides in a rhythmic motion.

This move engages your core and gets your blood flowing. Add it as a warm-up or as part of a dynamic flat belly fitness plan.

12. High Knees

This cardio-driven move burns belly fat while engaging the core. It’s fast, simple, and highly effective.

Run in place, bringing your knees up as high as possible. Swing your arms to keep momentum and maintain a tight core throughout.

This is an excellent choice for any HIIT core routine. Try doing it in 30-second bursts for maximum fat-burning impact.

13. Hollow Body Hold

Popular in gymnastics, the hollow body hold builds isometric core strength and teaches body control.

Lie on your back, arms extended overhead, legs lifted and slightly off the floor. Your back should stay flat against the mat as you hold the position.

Even 20 seconds of holding this position can light up your midsection. It’s one of the best core balance workouts out there.

14. Spiderman Plank

This advanced plank variation boosts your core and upper body strength while improving mobility.

From a forearm or high plank, bring your knee to the outside of your elbow, alternating sides. Focus on keeping your hips low and body steady.

This move works deep abdominal muscles, obliques, and even your lats. It’s a great way to level up your abdominal muscle exercises.

15. Tuck Jumps

This explosive move builds power, burns fat, and challenges your entire core. It’s high-impact, so make sure to warm up first.

Jump straight up, tucking your knees toward your chest. Land softly and reset. Try sets of 8–10 reps for a quick burn.

Tuck jumps spike your heart rate, making them a great addition to any fat-loss workout. They’re the cherry on top of a killer core day.
