The benefits of HIIT training (High Intensity Interval Training) can be particularly beneficial if you are time poor or training for endurance.  These short focused bouts of intense exercise impact positively on performance when competing and also fit in with busy lifestyles.


HIIT involves short bursts of intense exercise alternated with recovery periods and is a time-efficient way to exercise. Typically, a HIIT workout will be 20 minutes in duration and it can produce health benefits similar to twice as much moderate-intensity exercise; it also trains the different energy systems leading to increased physical fitness and performance in other activities. HIIT uses our anaerobic energy system as opposed to our aerobic system which is typically used in cardio exercise.


Let’s look at how the aerobic and anaerobic energy systems use oxygen.  Aerobic means “with oxygen” and anaerobic means “without oxygen.” Aerobic exercises such as running, cycling and swimming require oxygen for fuel; they cause you to breathe faster and more deeply, maximising the amount of oxygen you can take in.

Anaerobic exercises do not rely on oxygen for fuel. With short and intense periods of exercise you can’t take in as much oxygen, so muscles fatigue more quickly. However, the benefits of anaerobic exercise don’t rely on endurance, so this response isn’t a bad thing!


At FastTrack Fitness we deploy a range of training techniques to exercise both energy systems. We incorporate cardio, strength and HIIT. If you are looking for great results in a short time we’d recommend looking into training with EMS

We are qualified to deliver both traditional personal training methods and EMS to get you great results.
