For the purpose of this blog I am going to dive into exactly what high intensity interval training (HIIT) is, why it is often confused with sprint interval training (SIT) and guide you through getting the most out of your workouts. There are host of physiological adaptations that take place within the body depending on your modality of exercise, however after reading this post I hope you have gained more clarity on the how and why of the situation and can further implement a more structured approach to your workout regime.
