Anyone who's tried endless abdominal exercises knows how tough it is to eliminate that "belly bulge."
Fortunately, combining targeted training with smart nutrition—like the proven 4-week program below—makes it achievable. Ready to transform your core? Watch and get started:

As a fitness professional with years guiding clients to six-pack success, I can confirm this challenge is straightforward and effective. Follow these rules to shed belly fat in 4 weeks:
1. Perform the 6 exercises below for 1 minute each, without pausing between them. Complete 3 sets, resting no more than 2 minutes between sets.
2. Train 3 days a week, rest 1 day, train 2 days, rest 1 day. Repeat for 4 weeks.
3. Start on Monday; rest on Thursdays and Sundays.
4. Add 30-60 minutes of walking, running, or jogging daily—every day.
5. Avoid bread, pasta, sugary, or high-fat foods.
6. Prioritize vegetables, poultry, and fruit.
7. Enjoy occasional dairy, lean meats, eggs, nuts, and similar in moderation.
Stick to this program for at least 4 weeks. Noticeable changes in your waistline typically appear after the first month.
If you feel a burn in the early days, that's your abs adapting—keep going until you hit your goal!
