High Intensity Interval Training

High Intensity Interval Training (HIIT) is an exercise modality where exercise is performed at a high intensity or all out effort for a period of time (normally 10-30seconds) followed by a period of lesser intensity training. These periods are referred to as intervals. 

An example of HIIT Training is Tabata. 

Other intensity based exercise modalities commonly used are:

• Moderate-Intensity Continuous Training (MICT)
