Ahh you know you have had a good night if you wake in morning to find you have shit the bed
On day 4 don't know if your planning on doing your cardio with your workout, I wouldnt advise it, should be aleast 4 hours before your workout (only on this day)
For your depletion workouts I would up your volume abit, it's take 12 sets to deplete your glycogen. So if your doing it over two days 6 sets each day would be good, you can do less on your secondary muscles such as arms ect
