Ok, I see your point, however what this topic USUALLYis refering to is much less extreme. With that advent of HIT training, hitting a body part once a week became very popular, when all of the scientific research suggests that not only is a much higher frequincy of training usually not overtraining, it actaully yields faster gains. I'm not advocating weight training 8 hours a day 7 days a week for optimal gains, however if that person limited their other researches to recovery, one could do this without overtraining, yes. With a perfect diet, 10-12 hours of sleep a day, possibly a little extra help from drugs, this could be done without overtraining for an extended period of time, and ther person could see gains in size and strength, and would probably find it very easy to remain fairly lean year round.
