> One way to conceptualize, Specificity Rating, especially if you plan on performing adhoc workouts:
> 
> - Pure – You spent a majority of your time at or near the Focus intensity.
> - Polar – You spent a majority of your time at Endurance intensity with efforts above your Focus intensity.
> - Mixed – You had a mix of Endurance, Focus intensity and efforts above and below it.
