The layout is a 6-8 set, 15-20 rep workout, Bill. I have tried it 2x before, on a chest workout and once on a shoulders workout. If the muscle was severely broken down the first day with a high intensity workout (the point where your pecs hurt just from bouncing em), i found the 2nd workouts to be a bitch, lol and i mean seeing a big guy like me sitting there Cable pressing 40lbs and feeling a burn, BUT the following day, did not feel too broken at all.
Also Bill, from what i read, it is NOT something that should be employed often. Its recommended you do Back to backs no more than once a week, and that you should space it about 2 or 3 months between muscle groups. Having a 4 day split like i do, i could essentially cycle a 1 month on 1 month off and keep a 2month gap between muscle groups.[/quote]
Yes. The Smolov routine, for example, does it only once per week, and for only three weeks in succession. And if discussing the full Smolov routine (as opposed to "Smolov Jr,: which is only those 3 weeks) it is only those 3 weeks out of 12 weeks, or 13 if counting the end taper.
And no one recommends doing Smolov’s back-to-back-to-back-to-back through the training year, either.
My point just was that it can be doable and productive, yet here in the West most of us have been pretty thoroughly programmed to fear this and to consider it an absolute to not train a muscle on consecutive days, except for calves and forearms widely being considered acceptable.
And with regard to the original question of the second workout being a much lighter one on the immediately following day, I agree that that should not be done all the time either, but that (contrary to fears) it can be doable and productive when used judiciously. Based on experiences of others: I haven’t myself done that.
