4 Power Moves That Flatten Your Stomach in 30 Days

Blast belly fat and tighten your core with these 4 dynamic, full-body power moves.

A flat stomach isn’t about endless crunches—it’s about choosing exercises that engage the entire core while burning extra calories. After 40, the midsection often holds on to stubborn fat, but the right moves build strength, stability, and definition at once. Power-focused exercises train your abs to work with your hips, back, and shoulders, creating a leaner, tighter core.

The secret lies in intensity and muscle recruitment. These movements challenge balance, coordination, and strength at the same time, turning each rep into a full-body fat burner. You’ll feel the difference in how your core supports you during workouts and everyday life.

Stick with these four moves for 30 days, and your stomach won’t just look flatter—it will feel stronger, tighter, and more powerful. Here’s how to make it happen.

  • Keeping hips steady, lift one hand to tap the opposite shoulder.
  • Alternate sides, moving slowly and with control.
  • Perform 10–12 taps per side.
