High-intensity interval training (HIIT) has been shown to significantly enhance fat loss. This training method involves alternating between short bursts of intense activity and periods of low-intensity recovery or rest. HIIT can elevate the heart rate and increase the metabolic rate both during and after workouts, leading to greater caloric burn compared to steady-state cardio. It may also boost fat oxidation and improve insulin sensitivity. The efficiency of HIIT workouts allows participants to achieve fat loss results in a shorter duration, making it an effective strategy for maximizing fitness goals.
