What are the benefits of interval training?
1. Intervals vastly reduce boredom. Traditional steady state cardio training can become quite boring. HIT offers more variety and excitement to your workouts.
2. Interval training increases post-exercise energy expenditure (calories burned following exercise) more than steady-state exercise, which means that more fat is burned. After intense exercise, the body needs extra calories as it works to repair muscles, replace energy stores (i.e. carbohydrate) and restore the body to its normal state (e.g. reduce heart rate). As this can take many hours, you will keep on burning more calories long after the workout is over. In fact, research shows that metabolic rate is higher for several hours following interval training compared to steady state exercise.
3. Interval training stimulates the respiratory system, cardiovascular system and nervous system to a greater degree. Therefore, more fat and carbohydrates are burned to support the expanding energy demands of the body during, and after, intense exercise.
4. Interval training increases the activity of enzymes involved in fat burning. Research has shown that after a bout of interval training there is more fat in the blood (i.e. free fatty acids), which is an indication of more fat, being used for energy production.
5. HIT burns more calories. As an example, 30 minutes on an Elliptical machine using a steady state program will burn roughly 292 calories, whereas 30 minutes of intervals will burn approximately 584 calories!
