Thank you for elaborating.
I maybe make a mistake in mentally letting intensiveness fall under the umbrella of intensity. I suppose another word worth using in this context is that the 1A wants their training to be hard. A grueling slow tempo, despite using relatively less weight, is this subjectively hard work. Sure, a pump set can also be painful it’s that straining quality which is somehow so appealing to the 1A if I’m not mistaken?
If correct, the appeal of that straining quality drives a lot of consequences with regards to programming? Methods such as clusters, rest-pause, ramping, waves overloaded eccentrics,… are all applicable tools that align with the intensiveness need.
