I watched one of the first videos of CJ doing the program, and he does say it’s 10 sets of 10, with a specific rest period (i think they said 90 seconds). This is basically German volume training, except when I was reading about GVT, it was just one compound movement, not any support exercises, and 60 seconds of rest. This seems like he’s more or less using that template, but bumping up the volume even more. I hadn’t heard of Alan before they made this blog post though, so I can’t comment on his qualifications. All I can say, is that Charles Poliquin claims to be the one who introduced Americans to German Volume Training and he complained about people trying to modify it. It’s already a tried and true system, and people think they can make a better version, but most of the time, they can’t. That said, I don’t see anything wrong with this one, but it is a boatload of volume, and if done properly, could likely push a lot of people into an overtraining state. Still interesting though.
