Dynamic/Repetitin Effort (DE/RE) on Texas MEthod Volume Day
In PPST2 on pages 126-127 you go into detail about Dynamic Effort work in conjunction with the Texas Method. Most templates and questions that I've seen stem from the idea of using RE/DE work on the Intensity Day. However near the end of the section you briefly mention the idea of using the RE/DE work as the stresser on the Volume Day with some maximal work, heavy singles, etc... as the stresser on the Intensity Day.
My questions are thus:
When would a trainee find it appropriate to institute the DE/RE work on Volume Day?
Would it be a requisite that DE/RE work was done on Intensity Day prior to it being used on Volume Day?
Would moving the 5x5 work on Volume Day into a DE/RE rep scheme be a viable alternative when a stall is looming/occurs?
