The high-intensity interval training (HIIT) strategy focuses on maximizing workout efficiency by alternating between intense exercise and short recovery periods. This method accelerates the heart rate and burns calories in a shorter time frame compared to traditional workouts. HIIT can maximize fat loss while improving cardiovascular fitness and can be adapted to various fitness levels. It also fits well into busy lifestyles as it requires less time than longer, steady-state cardio sessions, maintaining the benefits of physical activity.
