6 Best HIIT Treadmill Workouts for a Flat Belly


Looking to shed some belly fat and improve your cardiovascular health? Consider incorporating high-intensity interval training (HIIT) treadmill workouts into your routine. HIIT involves intense bursts of exercise followed by short recovery periods, maximizing calorie burn and boosting metabolism long after your workout is done. By combining the benefits of running with the fat-burning power of interval training, HIIT treadmill workouts can be a great tool for weight loss.


As we age, maintaining a flat belly becomes more challenging due to hormonal changes and a decrease in muscle mass. However, regular HIIT sessions can help combat these changes by burning calories quickly and building lean muscle, essential for boosting metabolism and achieving a toned physique.


If you're unsure where to start, certified personal trainers have shared their top HIIT treadmill workouts for a flatter belly. Check out the workouts and detailed instructions below.
