First off, that is overtraining - especially if you don't have a refeed of some sort (supplements, snack of carbs, protein shake, etc..) in between.
After your first bout of training, your body will be in catabolism - breaking down the muscle, yada yada yada
This is why post WO nutrition is important. This is also why you shouldn't do cardio immediately after weight training (unless you had slow-acting preWO protein and carbs/some sort of glucose before the cardio)
In AM/PM splits, it is recommended that there be at least three hours between the training sessions... so in theory you could do all of this if you had the right nutrition, and at least three hours between, but then think of how much time is spent at the gym.
na i think those exercises are all thts needed really. i trained mentzer style for years and found that they are perfect in that thers no/very little overlapping.
Not to get this thread off topic but looking at jonny routine reminded me of Brian routine in the faq...which i have always been a little puzzled by.
Brian says for his routine he uses 2 sets per exercise. So say for Chest does he do 4 sets a day, like 2 sets for chest in morning and 2 in evening? Or is it 1 set in morning and 1 in the evening? I got confused on his total sets per week for his bodyparts...I only ask this b/c he is a condition lifter like myself and i was seeing what kind of volume he uses per week for this muscle groups.
