I was struck by how the peak heart rate was almost exactly the same for every rep starting with about the 3rd one. I was also surprised by some of the stuff Jakob said about doing the same sessions week in, week out, year in, year out., giving your body a fairly constant load. Also he said that you should have periods where you are carrying fatigue from one workout to the next but you do the workouts anyway.
To me, this is kind of the opposite of what Renato preaches. My interpretation of Renato's training is to always keep the body guessing by switching things up. Also, Renato gives an athlete a hard workout and the schedule isn't written in stone for the next workout because he wants to see how the athlete recovered from that hard workout.
I'd be curious what Renato thinks of Jakob's training and the double threshold concept. Some of Renato's "Special Blocks" might superficially look like double threshold a la Jakob but they are much harder. One of Renato's principles for the "Special Blocks" is to go into them well recovered and to also recover well after you do them.
