CNS - Workout Planning

Hey!

I have been trying to get most of my heavy CNS-training on mondays and tuesdays, to get 5 days off. But the thing is: I have understood it this way, that exercises that doesen’t involve much weight, but still are heavy (for example: i don’t barbell-biceps-curl more than maybe 40-50kgs, compared to my squat this is light weight, even though i get totally worn out biceps wise doing the exercise) is not very cns-exhausting.

Therefore I have heavy squats, heavy deadlifting, heavy benching all gathered on monday and tuesday, and do things like front-squat with lighter weights, chins, narrow grip bench… you get the picture: thursday and friday… am i thinking the right way?
