High-intensity interval training (HIIT) is one of the most effective forms of exercise for burning fat. This training method involves alternating short bursts of intense activity with periods of rest or lower-intensity exercises. HIIT boosts metabolism and encourages greater caloric burn during and after workouts, a phenomenon known as excess post-exercise oxygen consumption (EPOC). Additionally, HIIT can improve cardiovascular fitness in a shorter time compared to traditional steady-state cardio, making it a popular choice for those aiming to lose fat efficiently without lengthy workouts.
