HIIT, or High-Intensity Interval Training, involves alternating between intense bursts of exercise and short recovery periods, leading to efficient cardiovascular benefits and increased caloric burn. In contrast, traditional cardio workouts, like steady-state jogging, maintain a consistent pace for an extended duration. HIIT can typically yield faster results in fat loss and fitness improvements due to its intensity, making it a time-effective alternative. Both methods have unique advantages, and incorporating a mix can optimize overall fitness.
