4 Effective Exercises to Tone Your Stomach in Just 30 Days

A flat stomach isn’t about performing endless crunches—it’s instead about selecting exercises that engage the entire core while burning additional calories. After the age of 40, the midsection tends to hold onto stubborn fat, but the right exercises can simultaneously build strength, stability, and definition. Power-based exercises train your abs to work effectively with your hips, back, and shoulders, forming a leaner, more defined core.

The key is in the intensity and muscle engagement. These exercises test your balance, coordination, and strength simultaneously, making each repetition a full-body fat-burning workout. You’ll notice a difference in how your core supports you during both workouts and daily activities.

Commit to these four exercises for 30 days, and not only will your stomach appear flatter, but it will also feel stronger, tighter, and more powerful. Here’s how to achieve that goal.
