7 Easy Exercises for a Flat Stomach and Small Waist

Sculpt your core, melt fat and enhance your posture — all without ever leaving home — with these seven easy at-home exercises, just a few minutes of which you need to do each day.

1. Turning Torso (Seated or Standing Twist)

Target: The muscles that are responsible for these actions are the obliques, the rectus abdominis, and the transverse abdominis.

How to Do It:

1. Either sit on the floor with one leg extended forward and the other bent with your foot near your inner thigh, or stand tall with your feet hip-width apart.
2. Place your opposite hand behind you for support, or place your hands on your hips if you are standing.
3. Exhale and twist your upper body toward your bent knee (or to the right or left if you are standing), keeping your back straight.
4. Place your opposite arm over your knee or reach across your body.
5. Hold for 10 seconds and feel your obliques squeeze.
6. Inhale and slowly return to center.
7. Repeat on the other side.
8. Do 10 reps per side, 3 sets.

Tip: Keep your hips stable and twist from your waist or core only, not your arms or neck.

Why It Works: This gentle twist engages the obliques and deep core muscles through rotation. It cinches the waist, reduces side fat (i.e., love handles), improves spinal mobility, and helps create a slimmer, more tapered midsection. Additionally, it supports better posture.

2. Single Leg Lift Circles – Hip, Waist & Lower Abs

Targets: Hip flexors, lower abs, obliques, glutes, and abductors.

How to Do It:

1. Lie flat on your back with your arms stretched out to your sides (palms facing down) to maintain stability.
2. Lift one leg straight up (or bend it slightly if it is tight) while keeping the other leg on the floor or slightly lifted.
3. Exhale and begin making slow, controlled circles in the air (forward for 20 seconds, then reverse).
4. Keep your hips grounded and avoid rocking or arching your back.
5. Switch legs after 20 seconds.
6. Time: 20 seconds per direction per leg × 3 sets

Why It Works: Circles engage the hip stabilisers and deep core muscles, while lengthening the lower abdominal muscles. This tones the sides of the waist, strengthens the lower belly, improves hip mobility and helps create a slimmer, more defined transition from leg to waist.

3. Heel Touches – Obliques & Side Waist Sculptor

Targets: Obliques, rectus abdominis, and core stability are all important for a well-balanced workout.

How to Do It:

1. Lie on your back with your knees bent and your feet flat on the floor, hip-width apart.
2. Extend your arms along your thighs with your palms facing inward or behind your head with your elbows wide.
3. Lift your head and shoulders slightly off the floor to engage your core.
4. Exhale and slide your right hand toward your right heel to crunch your obliques.
5. Hold for one second and feel your side waist contract.
6. Inhale and slowly return to center.
7. Repeat on the left side, alternating continuously.
8. Do 30 total touches (15 per side) for 3 sets.

Tip: Keep your lower back pressed down and move from your core, not your arms.

Why It Works: Heel touches isolate the obliques through side flexion. They carve the waist, reduce love handles and improve coordination. They also help to create a tighter, more defined midsection without putting strain on the lower back.

4. Side Plank – Ultimate Waist & Core Tightener

Targets: The muscles that are targeted are the obliques, the transverse abdominis, the hips, and the shoulders.

How to Do It:

1. Lie on your side with legs stacked and forearm on the ground.
2. Lift your body so it forms a straight line from head to toe.
3. Hold for 3 seconds, then lower.
4. Switch sides and repeat.
5. Do 20 total touches (10 per side).

Why It Works: The side plank intensely targets the obliques to define the waist and the deep core (the transverse abdominis) to create a pulled-in belly. It strengthens lateral stability, reduces love handles and creates a tighter, firmer waistline, while also improving posture and balance.

5. Oblique V Crunch (Side V-Up)

Targets: Obliques, rectus abdominis, and hip flexors.

How to Do It:

1. Lie on your right side with your legs together and your right forearm on the ground for support.
2. Place your left hand behind your head with your elbow wide.
3. Exhale and lift both legs straight up, bringing your torso forward to meet them and forming a “V” shape.
4. Squeeze your obliques hard at the top.
5. Inhale and slowly lower with control.
6. Complete all reps, then switch sides.
7. Reps: 10 per side × 3 sets

Beginner Modification: Bend your knees or only lift your upper body.

Why It Works: This advanced crunch tones the obliques and the entire abdominal region, improving core endurance and definition. With consistent practice, it carves the sides of the waist, lifts the lower belly and helps create a V-shaped midsection.

6. Bicycle Crunches

Target: Rectus Abdominis (Upper and Lower), Obliques, and Hip Flexors

How to Do It:

1. Lie flat on your back with your hands lightly behind your head (keep your elbows wide and don’t pull on your neck).
2. Bend your knees and keep your shins parallel to the ceiling.
3. Press your lower back flat and engage your core.
4. Exhale and lift your right shoulder toward your left knee while straightening your right leg (keep it low).
5. Twist your torso and squeeze your obliques hard at the top.
6. Inhale and switch: Bring your left shoulder to your right knee and straighten your left leg.
7. Alternate smoothly, keeping your lower back pressed down.
8. Do 20 controlled reps per side (40 total) for 3 sets.

Why It Works: Bicycle crunches are one of the exercises that activate the core the most. They target the upper and lower abs through flexion and the obliques through rotation, sculpting the sides of the waist, tightening the midsection and boosting calorie burn for fat loss.

7. Windshield Wiper – Obliques & Lower Abs Finisher

Target: Obliques, lower abs, and core stability

How to Do It:

1. Lie on your back with your arms extended out to the sides in a T-shape (with your palms facing down for stability).
2. Lift your legs straight up toward the ceiling with your knees together and your legs perpendicular to the floor.
3. Engage your core and press your lower back flat.
4. Exhale and slowly lower both legs to the right, as close to the floor as is comfortable without lifting the left shoulder.
5. Pause for one second at the bottom.
6. Inhale and bring your legs back to the center using your abs.
7. Repeat on the left side, alternating slowly.
8. Do 15 reps per side (30 total) for 3 sets.

Tip: If your back arches or your legs feel too heavy, bend your knees slightly. Keep your movements controlled.

Why It Works: The Windshield Wiper controlled rotation deeply engages obliques and lower abs. It carves the waist. It reduces love handles. It flattens the lower belly pooch. It improves rotational strength and core control.
