High-intensity interval training (HIIT) is an effective workout that alternates between periods of working at maximum capacity and low-intensity recovery. Here are three reasons to incorporate HIIT into your workout.
1) Burns more fat in less time. One study found that people lost more fat by doing 30-second sprints over a period of four to six minutes, with rest periods in between, than they did through 60 minutes of walking at an incline on a treadmill. Furthermore, HIIT increases the metabolic rate for as much as 24 hours and increases the muscles’ ability to use fat for energy.
2) Better at preserving muscle. Muscles, which burn more calories per hour than fat, are key to losing and maintaining weight loss. Cardio-based exercises preserve fewer muscles as they lead to a calorie deficit while HIIT increases weight loss and preserves muscles.
3) Curbs cravings. As cardio leads to a calorie deficit, food cravings increase. Studies have shown that HIIT can result in brain changes that decrease hunger and increase fullness from consumed food.
