In this block, we will focus on creating high-intensity stimulus, followed by rest. Performed at least 5 rounds.

General HIIT Guidelines

* High intensity should be above 80%HR max (higher or lower depending on ability). Durations can be anywhere from 10s per interval to 4 minutes. 
* Duration of Interval and Intensity are inversely proportional
* Recovery periods can be active using aerobic intensities or complete rest
* W:R Ratio are 1:1 or greater rest than work, as much as 1:12 for intervals with maximal intensity.
* Choose from the 4 main modalities (Cyclical, PHA, WBI, ADL’s) when designing a workout or section of a workout
