In this block, we will focus on creating very high-intensity stimulus, followed by minimal rest. Perform for maximum 7 minutes

General HISS Guidelines

* High intensity should be above 80%HR max (higher or lower depending on ability). 
* HISS workouts are typically 4-15 minutes. Elite athletes may train as long as 20 minutes.
* Rest is minimal during and between a working block.
* W:R Ratio are 2:1 or greater work than rest
* Choose from 3 modalities (Cyclical, PHA, WBI) when designing a workout or section of a workout. A combination of these modalities may be best (Mixed-Modal).
