i'll take your word for it, and agree for the most part with you and brownbrown...
ive done weeks on weeks on months of brutally long and heavy workouts... though im slowing down a lot with age...
i do think sometimes less is more, but only after you reach a certain point...
idk how new you are (ill look at your log next) to lifting, but it is much harder imo for someone newer to training to overtrain... this is probably opposite of what many think, but as the intensity and weight increases, you need more rest to recover...
when you are new and training to muscular failure, imo your CNS will give out last... it can take a beating, but once its beat it can take a while to recover...
