I just started my routine based on CC I and II.

I went with Veterano (six-day per week protocol, you work one of the big 6 in each day) with some modifications based on coach Wade opinion on bridge and handstand pushups work. He says for bridge work it's important to master close squats (progression number 6) and hanging knee raises (progression number 6).
And for handstand pushups you need to be able to get to step 6/7 for the pushup series to start training vertically.

So I'm doing grip and calf work instead (CC II).
