The surprising thing about HIIT is that it involves such a small total amount of exercise. Reduced abdominal and subcutaneous (just under the skin) fat.Decreased fasting insulin and increased insulin sensitivity.Significantly increased aerobic and anaerobic fitness.The payoffs of pushing yourself with HIIT are plentiful, and include: Sprint interval training (SIT) is a type of high-intensity interval training that pushes beyond this level to 100% or more of maximal aerobic capacity, or an exertion level of 10. High-intensity interval training is done at a submaximal level around 80-95% of maximal aerobic capacity. Recovery intervals are equal to or longer than the speed intervals. High-intensity intervals are done at an exertion level of 7 or higher, and are typically sustained for 30 seconds to 3 minutes, although they can be as short as 8-10 seconds or as long as 5 minutes the higher the intensity, the shorter the speed interval.

Most endurance workouts, such as walking, running, or stair-climbing-are performed at a moderate intensity, or an exertion level of 5-6 on a scale of 0-10. HIIT is used by athletes and everyday exercise enthusiasts to reach performance goals and enhance fitness and well-being. Looking for a way to add variety to your exercise plan while taking your fitness to the next level? High-intensity interval training (HIIT) is a cardiorespiratory training technique that alternates brief speed and recovery intervals to increase the overall intensity of your workout.
