Strictly speaking, HIIT is not a simple aerobic exercise, but it is an effective training for burning fat (some even recommend it as the fastest way to burn fat).

The traditional concept is to link exercise to reduce fat and aerobic training. In fact, aerobic energy supply must start after 2 or 3 minutes of continuous exercise and reach its peak in about 30 minutes. The popular view now is that high-intensity exercise can also effectively consume fat, and exercise design such as HIIT can improve the basal metabolic rate after exercise and maintain it for a long time. High metabolic rate means more fat consumption, so its fat-reducing effect is longer and stronger than that of ordinary low-intensity aerobic exercise.
