Well, who knows if he was training other bodyparts. I don't know.
As stated, I have trained 7 days per weeks for weeks straight, however I did rotate all my bodyparts. According to Coach, you can do this and not overtrain. Dont get me wrong, I do not advocate training the same bodypart every day, but you can train 7 days per week as long as you rotate the muscles you work each day.
Ive never had any negative experiences from training this much.
I've tried the 7 day thing, would love for it to work. I think the fact i rely on stimulants too much, it backfires against me. Stims work great when used 4 days and that's my best split. Would like to do 5 day split, but the part where you train 3 days in a row, no matter how easy the 3rd day, just breaks me.
Mike Mentzer had a great saying on this topic. Something along the lines of "One's ability to sustain a 20, 30 or 60 minute workout is like one's ability to stay out in the sun. Some get a sunburn after 20, 30 or 60 minutes. It's about finding out how much time you can spend in the sun without getting burned"
