High-intensity interval training (HIIT) methods often include exercises that are almost exhausting for 20 seconds to a few minutes, alternating with breaks or light exercises.
HIIT is famous for being good for the heart and burning many calories in a short time. This is thanks to the body using two energy systems at the same time: anaerobic (quick explosion) and aerobic (longer maintenance), creating a fast and stable energy burning effect.
Meanwhile, super-short high-intensity exercises focus on very strong waves of exercise but only last about 30 seconds or less. This form is mainly based on anaerobic systems.
Although short, these exercises still stimulate strong metabolism, creating the after-exercise calorie burning effect (EPOC) - meaning the body continues to burn energy even after resting. Just 30 seconds of extreme exercise, the body has entered a high energy burning state, helping to increase fat reduction efficiency and activate muscles better than light, long-lasting exercises.
Another plus point is that short exercises cause less psychological pressure. Only 30 seconds, so it is easy to start, easy to maintain, especially suitable for busy people. When exercising regularly, these short periods of time are still accumulated and bring clear effects in burning calories and reducing fat.
Regarding cardiovascular health, high-intensity exercise in a short time also brings its own benefits. If jogging or cycling help increase endurance gradually, short but strong exercises make the heart adapt faster, thereby improving the ability to regulate heart rate and increasing cardiovascular health.
In addition, this form of exercise also helps the body be more flexible in using energy, switching between sugar and fat more effectively. This not only supports fat reduction but also improves metabolism, including increasing insulin sensitivity and better blood sugar utilization.
