I asked CT about training while doing the pulse fast in the training lab a little while ago. If I remember correctly, he said that he likes to do a neural charge WO in the morning and a little extra stuff (20-30 min blasts workout is what I do) at night on the day of the fast. For the day after he said you don't need to train twice. Just increase the overall volume of the workout your doing, making sure you don't over do it on the eccentric portion of the lift. Just control the weight on the way down but don't purposely go slow.
I like to do a circuit of about 3-4 exercises for chest with basically no rest in between exercises and then 3-4 exercises for back and I repeat for 4-5 circuits each. I really feel like Im shuttling all the MAG-10 to the muscles Im working and the pump is insane.
Hope that helps.
