High-Intensity Interval Training (HIIT) is a workout method that alternates between short bursts of intense exercise and periods of rest or lower-intensity activity. This approach can improve cardiovascular fitness, burn calories, and enhance overall endurance in a shorter amount of time compared to traditional workouts. HIIT can include various exercises, such as sprinting, cycling, or bodyweight movements like burpees and jump squats. Sessions typically last from 10 to 30 minutes, making it a convenient option for those with busy schedules. It is suitable for different fitness levels and can be easily modified to meet individual needs.
