This guide brings you 30 quick flat belly workouts—perfect for busy schedules and effective for all fitness levels. These exercises combine bodyweight movements, cardio bursts, and core toning techniques to help you lose belly fat fast and feel fantastic.

1. Standing Oblique Crunches

Standing oblique crunches are a great way to target the side of your waist while staying upright. Unlike traditional crunches, they’re easy on the back and accessible to all levels.

This move works your obliques and helps define your waistline. It also improves your balance and posture, making it perfect for quick core activation sessions.

To perform, stand tall, bring your right elbow toward your right knee as you crunch sideways, then switch sides. Perform 20–30 reps for a solid burn.

2. Plank Jacks

This core-focused cardio move elevates your heart rate while challenging your abdominal endurance. Start in a plank position and hop your feet in and out like a jumping jack.

Not only does it torch calories, but it also strengthens your shoulders, core, and lower body.

Modify by stepping one foot out at a time for a low-impact version. Try 30 seconds of plank jacks followed by a rest for 10 seconds, then repeat for 3–4 sets.

3. Reverse Crunches

This low-impact yet highly effective ab move targets the lower belly—a notorious trouble spot.
