Day 1: Benefits of High-Intensity Interval Training (HIIT)

High-Intensity Interval Training (HIIT) has gained popularity for its effectiveness in burning calories and improving cardiovascular fitness in a short amount of time. By alternating between periods of intense exercise and short rest periods, HIIT workouts challenge your body to work at its maximum capacity, leading to increased calorie burn both during and after the workout. Additionally, HIIT has been shown to improve insulin sensitivity, boost metabolism, and enhance fat loss while preserving muscle mass. Whether you're short on time or looking to take your fitness to the next level, incorporating HIIT into your workout routine can help you achieve your goals efficiently and effectively.
