High-Intensity Interval Training (HIIT) is the most time-efficient fat-burning workout method available. Here is the science behind why 30 minutes of HIIT beats 60 minutes of steady-state jogging.
When you run on a treadmill at a steady pace, you burn calories only while running. HIIT is different. By spiking your heart rate near its maximum for short intervals, you create an oxygen debt in your body. Your body takes up to 24 hours to recover, meaning you continue burning calories while sitting at your desk or sleeping.
Crash diets and excessive cardio lead to muscle loss. HIIT incorporates explosive, resistance-based movements like squat jumps and mountain climbers that signal your body to preserve muscle while shedding fat.
