I believe there are more conclusive studies out that show the testosterone/GH secreting benefits of heavy compound movements. I'll stick to those.
Maybe your right! But I have tried this the past few days in the gym and I feel like it is working because like u say your body does let u no but It feels my body is already telling me to carry on with this. I feel the pump in my muscles is more intense and the next day my testosterone seems to be increasing..... Whether its all in the mind I no but I'm just gunna carry on with this for a few weeks and see the outcome.
Maybe by rushing more, you are obviously increasing the intensity of your W/O's, no!?
Also, by changing things up, you are no longer adapted to what you were doing
The one problem I see with it for me, is on the big exercises ie: squats, deadlifts, heavy rows, OHP's or BP's where the weight I would be using 80%-85%-90% of my 1RM, is going to be hard for me to be at optimum recovery and ready to go again in under 60 secs, especially as I get past the 3rd/4th/5th... sets.
Sure smaller muscle groups or iso moves why not!?
The definition of intensity is percentage of 1RM i.e. if you lift at a higher intensity you are lifting a heavier weight on that given lift.
Decreasing rest periods will result in using lower weights and therefore you would be training at a lower intensity.
Disagree with definition specifics.
Many "could" use the same weight, but shorten rest time, increasing power out put to finish the set, say an rpe scale (rate of perceived exertion).
20 rep squats can be more intense than a heavier weight for 2x10 reps. It depends on the RPE at the 20th compared to the RPE at 10th. So I can't say it is "more" weight alone, that determines intensity factors.
But I see what "you're saying" too.

Now we are getting into semantics.
What you are describing Paul is a mix of relative intensity (How close to failure you are working) and RPE.
Absolute intensity, or when you see intensity in a strength and conditioning program refers to the % of the 1rm.
So, although 3 x 10 @ 70% is not working at 100% absolute intensity (you are not using your 1rm) it could be at 100% relative intensity.
Either way, manipulation of rest periods to achieve a certain goal is what separates a good programmer apart from a "mix that sh*t up" bro.
What I am saying is the true definition of intensity in weightlifting is the percentage of 1RM and has nothing to do with perceived exertion.
High rep workouts may feel more intense in terms of exertion but do not fit the actual definition of intensity because a lower weight is used e.g. a back squat of 90% 1RM is a higher intensity than a back squat at 60% 1RM irrespective of the number of repetitions.
