10 Minutes Flat Belly Workout to Shrink Your Waist and Burn Fat

1. Pike and Extend

Targets: Upper abs (rectus abdominis), lower abs, hip flexors, shoulders, legs

How to do it step by step:

1. Lie faceup on mat, legs extended straight up over hips (90° angle), arms extended overhead (palms facing up).
2. Engage core — press lower back into mat.
3. Exhale → crunch upper body up, reaching hands toward feet (pike position — try to touch toes).
4. Inhale → slowly lower upper back toward floor while simultaneously lowering one leg straight toward floor (hover 2–6 inches above ground — keep leg straight).
5. Exhale → crunch back up, lifting lowered leg over hips again and reaching hands to toes.
6. Switch legs on next rep (alternate sides).
7. Continue for full time.
8. Reps estimate: 10–15 per side (20–30 total)

Why it works: This dynamic move combines a pike crunch, which intensely contracts the upper abs, with a leg extension, which deeply burns the lower abs and hip flexors. The reach-to-toe phase requires strong core engagement to lift the upper body, while the controlled lowering of the legs challenges the anti-extension muscles (the transverse abdominis). This exercise increases your heart rate to burn fat, improves coordination and tightens your entire midsection, making it one of the most effective bodyweight exercises for achieving overall core definition and reducing belly fat.

2. Chest Flye with Leg Extension

Targets: Chest (pectorals), abs (especially lower), hip flexors, core stability

How to do it step by step:

1. Lie faceup on mat, knees bent 90° over hips (shins parallel to ceiling).
2. Hold light dumbbells (or water bottles) in each hand, arms extended over chest, palms facing in.
3. Engage core — press lower back into mat.
4. Keeping right knee bent and stable, exhale → straighten left leg toward floor (hover 2–6 inches above ground).
5. Simultaneously lower both arms out to sides (like a chest flye — slight bend in elbows).
6. Hold bottom position 1 second — feel stretch in chest and burn in lower abs.
7. Inhale → return arms to center over chest and bend left knee back to 90°.
8. Switch legs on next rep (alternate).
9. Reps estimate: 10–12 per side (20–24 total)

Why it works: This leg extension targets the lower abdominal muscles and hip flexors, while the chest fly engages the pectoral muscles and requires you to brace your core in order to stabilise your torso. This combination increases your heart rate, burns fat and strengthens the anti-extension muscles (the transverse abdominis), toning your midsection while working your upper body — excellent for burning calories and achieving a tighter waistline!

3. Knee-Up with Overhead Press

Targets: Shoulders (deltoids), abs (deep core & hip flexors), glutes, lower back stabilizers

How to do it step by step:

1. Sit on mat with knees bent, feet flat on floor, holding light dumbbells (or water bottles) near shoulders (elbows by sides, palms facing in).
2. Lean back slightly (≈45° angle) — core engaged, back straight.
3. Exhale → extend both arms overhead (straight up) while simultaneously lifting feet a few inches off floor and bringing knees toward chest.
4. Hold top position 1–3 seconds — squeeze abs and glutes.
5. Inhale → slowly lower feet back down and bend arms to return dumbbells to shoulders.
6. Repeat continuously.
7. Reps estimate: 12–18 reps

Why it works: The overhead press builds shoulder strength and improves posture, while the knee-up activates the deep core muscles (the transverse abdominis) and the hip flexors. Leaning back slightly increases the demand on the core for stability. This exercise improves anti-extension strength, tones the midsection, boosts metabolism and enhances shoulder mobility, making it excellent for achieving overall core definition and improving functional fitness.

4. Lunge and Twist

Targets: Obliques, rectus abdominis, transverse abdominis, glutes (maximus & medius), quadriceps, hamstrings, hip flexors

How to do it step by step:

1. Stand tall with feet together, core lightly engaged, shoulders relaxed.
2. Exhale → step your left leg straight back into a lunge — both knees bend ≈90 degrees (front knee over ankle, back knee hovers just above floor).
3. At the same time, reach your left hand down toward your right foot (or shin) — feel the stretch in left hip flexor and oblique.
4. Inhale → push through your right heel to stand tall, lifting your left knee up in front of you to hip height (balance on right leg).
5. Bring both fists to chest level, elbows bent out to sides.
6. Exhale → twist your torso to the left (fists move toward left side) — keep core tight, hips facing forward.
7. Inhale → twist back to center.
8. Immediately step left leg back into lunge again and repeat.
9. Complete all reps on left side, then switch (right leg back).
10. 15 reps per side of 3 set

Why it works: This dynamic compound move combines lower-body strength (the lunge) with rotational core power (the twist). The lunge strengthens the glutes and legs, while the twist engages the obliques and deep core stabilisers (transverse abdominis) to resist rotation and stabilise the torso. It increases heart rate for calorie burning and fat loss, improves functional core strength (useful for everyday twisting movements), enhances balance and tones the waist by targeting the side abs. Adding a knee lift activates the hip flexors for extra lower ab work.

5. Standing Side Crunch

Targets: Obliques (internal & external), quadriceps (standing leg), hip flexors, core stability

How to do it step by step:

1. Stand tall on your left leg — left knee soft (slight bend), core engaged.
2. Extend left arm straight out to the side at shoulder height (for balance).
3. Lift right foot a few inches off the floor to the side (or keep toes lightly touching for support).
4. Place right hand behind your head, elbow bent out to the side at shoulder level.
5. Exhale → lift right knee up and out to the side while simultaneously crunching right elbow toward right knee (side crunch).
6. Squeeze obliques hard at the top — feel contraction along right side of waist.
7. Inhale → slowly lower right leg back down (don’t let it touch floor if possible).
8. Repeat on same side for full time, then switch sides (stand on right leg).
9. Reps estimate: 12–18 reps per side

Why it works: This standing exercise targets the obliques through lateral flexion (a side crunch), while also testing your balance and single-leg stability. The knee-to-elbow action activates the hip flexors and lower abdominal muscles, while the standing leg engages the quadriceps and gluteus medius to provide support. It improves functional core strength (side bending and rotation), sculpts the waistline (oblique definition) and boosts coordination. It is excellent for tightening the sides of the midsection and burning calories through standing instability.

These flat belly workout are excellent for sculpting the obliques and lower abdominal muscles, while also improving balance, coordination and functional core strength. They’re ideal for toning your waist, burning calories through standing instability and adding variety to your flat-belly routine.
