Marissa Nieves, Fitness Expert for the September 28 Day Challenge provides information on 3 ways high intensity interval training increases metabolism to help you lose weight:
High-intensity interval training, also known as HIIT, has become extremely popular in the fitness and health world as one of the simplest ways to increase cardiovascular health and metabolic function.
Here are 3 top reasons why HIIT is so well known for increasing metabolism.

1) EPOC

One possible outcome of HIIT is excess post-exercise oxygen consumption (EPOC) which increases caloric expenditure and also fat burning. The body’s metabolism has no choice but to increase to burn calories, sometimes up to 36 hours post-exercise. A recent study performed to ascertain the amount of fat and calories burned in high intensity training showed that HIIT workouts actually doubled the amount of fat burned to calories. Doubled! That’s something to talk about.

2) Lean Muscle

Another metabolic benefit to HIIT training is how easy it is to build and maintain lean muscle. When lean muscle is created, your body burns more calories than it would without the muscle. Building lean muscle is a simple way to increase your body’s average resting metabolic rate.

 3) Just Keep Swimming

While rest days are vital for recovery and reducing stress on the body, resting for two days in a row with no activity at all can slow your metabolic rate down fast. The 28 Day Challenges recommend at least one active recovery day per week. Active recovery allows the body to recover from training while supporting a healthy metabolism.
There is an endless list of reasons to include HIIT in your daily workout regime to boost your resting metabolic rate and improve overall health and bodily function through short bursts of high intensity exercise.
