HIIT training allows us to access the higher level energy need followed by recovery only to rebound back to the higher state of energy need. This back and forth helps us burn more calories than sustained longer workouts at a lower training rate and do so in less time.

HIIT is a wonderful way to fit exercise into your life in short bursts of time. The body has 3 energy systems and we need to train them all. The Creatine Phosphate (CP) system is for explosive energy – often used in weight training, Anaerobic Glycolytic System (A-G) system gets used in stop and go movement, bursts of energy, and at the top ends of our endurance curves – think team sports, sprints, etc., and finally the Aerobic System is where we sit most of the time. Cardiovascular training is about making this system broader. The other two have some issues – the side effects shorten how much work we can do for how long. Creatine gets used up quick in the CP system, the byproduct of the A-G system is acid build up that results in cramping and the muscle’s inability to use the oxygen for production of ATP (the body’s energy), but in the aerobic system we only get CO2 and sweat plus more energy as we continue to breathe. In this system we feel like we can go on and on and on. This is the system we want to expand to get more efficient at movement. Then life becomes easier for us to move within every day.
