Is There a Rest in the Workout?

If woeu're going to do short and really aggressive efforts, take more rest than you need. As that draws out towards purely an endurance style effort, the rest periods are going to be reduced but so is the intensity of the effort. Even though we've been predominantly talking about sprint days, rest is needed. You can see that in a five by five back squad as well which layers in very nicely with what you just said about class structure.
