Stumbled across this "study" a few days ago, just wondered what people thought of it. If you don't know it read below. An example of Casey's routine. A bit of text written by one of the subjects in Casey Vitor. Source for the above texts and images Now as you can see this growth seems to be too much to comprehend, it goes against every single fact we've been told before. My theory on how he did it is pretty simple, Casey was an absolute freak who had colossal mass before yet lost that before the experiment. Now as seems to be common knowledge it's easier to recreate muscle then to grow it in the first place. However even if the case of the man who conducted the experiment the growth was phenomenal, Arthur Jones gained 16lbs in 22 days later on after the success Casey gained. This was a man, who with my little research didn't have any history of body building. So how did he do it? Is there an actual truth to this idea? More on muscle memory Now I believe the result numbers will be difficult to replicate but do we have the formula correct? Is an increase in effort a direct correlation to the gains, or is there a way to get a large percentage of the results without putting in the equal effort? One advocate is Tim Ferriss and his 80/20 approach epitomized by the Geek to Freak concept ( here it is ) So a few questions to finish up : 1) How did Jones and Casey gain the mass or didn't they at all? 2) Is there a way to optimize or "hack" muscle gain, less effort = better gains? 3) How do you feel about decreasing the volume of one workout, instead working one heavy set to failure? Is it an approach you'd trial or something you don't believe would work? 4) What do you feel about the "Geek to Freak" concept? Please try to back up opinions with some kind of evidence, ideally contradicting studies but other informed opinions from message boards are fine. Just don't go "herp derp impossible i never do it".
