disagree. you should be training as hard as possible, as smart as possible.
also you are completely ignoring work capacity. if I train harder than you for longer than you, intelligently pushing my volume/intensity, I am going to outpace your "medium" pretty quickly. and in a year I will be able to recover from more overall work in a training week than you can.
are we trending away from the "TRANE HARD UFC BRO" mentality and the new fad is everybody gonna train like pussies all the time now? walking home at a slow pace because our heart rate variability monitor says were in the red?
Im sorry I entered this thread just to dump on you but a) this is sherdog and b) I am serious.
volume and intensity are both important. you dont have to choose one according to whichever training fad is fashionable. just manage them appropriately in a progressive fashion.
