Hiit

HIIT

HIIT stands for high-intensity interval training, a workout style that alternates short bursts of very hard effort with periods of rest or easier activity. A typical session might include repeated 20–60 second sprints or intense exercises followed by a minute or two of light activity to recover. This format lets you get a lot of cardiovascular and metabolic benefit in a shorter time than steady-state exercise, which is why many people find it efficient for improving fitness and burning calories. HIIT can boost heart and lung fitness, increase calorie burn after the workout, and improve blood sugar control for many people. Because the work intervals are intense, workouts can be adapted to different fitness levels by changing the length, intensity, or rest periods. It is not right for everyone: people with certain medical conditions, very low baseline fitness, or no recent exercise history should ease in gradually and consider medical advice first. Proper warm-up, good technique, and gradually increasing intensity help reduce the risk of injury and overtraining. Done sensibly, HIIT is a powerful tool for improving fitness in less time, but it should be matched to each person’s abilities and health status.
