15-Minute At-Home Abs Workout Routine for a Flat Stomach

You’re going to lose belly fat with this 15-minute HIIT circuit that includes fat-burning aerobic intervals and standing core workouts that do double duty as your belly actively heals.

Even though you can’t see your body losing weight, research has shown that high-intensity interval training (HIIT) sessions are more effective than standard cardio in decreasing abdominal body fat.

HIIT also helps to develop your core muscles, which helps to improve your posture and generate more drawn-in abs, resulting in a flatter stomach and sculpted core.

Eat flat-belly meals and avoid high-calorie items that contribute to weight gain.

How does it work?

Perform as many reps as possible for each exercise in a row with no rest.

The core strength moves twice as fast as the warm-up, recovery, and cool-down.

Rep the circuit three times more.

There is no equipment necessary and the total time required is 15 minutes.

1. Squat to Knee Lift Twist

Move 1:

Place your feet hip-width apart and your arms by your sides.

As you sit back into your hips, lower yourself into a deep squat and stretch your arms in front of your chest, palms facing in.

Move 2:

Stand up from a squat with your left leg balanced your right knee elevated in front of your hip, and your arms extended to the sides of your shoulders as your upper body rotates right.

Return to the beginning and retry it while switching sides.

Inhale while squatting and exhale on the twist as you bring your abs tighter to the spine while exhaling for a greater sensation.

Sets:

Perform three sets of as many repetitions as you can in less than a minute.

2. Side Leap and Balance

Move 1:

Lower yourself into a single-leg squat while balancing on your right leg, with your arm driving forward and your left arm back with elbows bent.

Move 2:

Push off with your right foot and leap up and over to your left foot, swinging your arms open the sides of your shoulders as though leaping sideways over a puddle.

Simultaneously, you should land in a single-leg squat on your left leg with your left arm facing forward.

Sets:

Rep the entire exercise on the opposing side, doing a high number of reps for a minute in three sets.

3. Crossing Climber

Start in a plank stance with your feet hip-width apart.

Bend one of your knees across to your opposite elbow, touch your keen to the arm, and leap rapidly to swap legs.

Sets:

Perform three sets of as many repetitions as you can in under a minute.

4. 180 Squat Jump

Move 1:

Stand with your feet hip-width apart and drop into a squat while swinging your arms back by your hips.

Jump up rapidly, spin to the right, then turn 180 degrees midair while swinging your arms in front of your body for momentum.

Move 2:

Squat down and swing your arms back by your hips.

Begin the cycle on the opposite side right away.

Sets:

Perform three sets of as many repetitions as you can in around a minute.

5. Laying Straight-Leg Bicycle

Move 1:

Begin by laying down with your feet together, knees slightly bent, hands clasped behind your head, and abs engaged.

Move 2:

While balancing, stretch your right leg in front of you with your toes pointed and rotate your upper body to the right.

Return to the starting position and repeat on the opposing side.

To bring your abs in tighter on expiration, always inhale while your feet are together and exhale when on rotation.

Sets:

Perform three sets of all the repetitions you can handle for a minute.
