Do you go with all out intensity every day? Or do you just squat what you can without putting so much of a grunt?
I read an interesting article on the bulgarian method that goes into some detail about the psychological effects of how hard you try to lift... they squat to a daily max WITHOUT any kind of mental arousal. the idea is that the CNS will not burn out if you are not very mentally aroused for your lifts, yet you are lifting 90% or more every day.
i cant find it now, but maybe youve heard of this? Related:
"In Squat Every Day, Perryman makes a compelling argument that, in many cases, the psychological stress of a workout contributes as much, if not more, to recovery debt than the actual workload of the physical activity itself."
