Ok, so I tried Poliquin's one day arm cure this past Friday with 14 15/16" arms, currently i'm at 15 3/16". So far i've gained 2/8" which isn't bad for only one day of training. So my point is, if there is anyone there with lagging arms and you have neglected their training for a while, the one day arm cure is going to do you some good.
If, on the other hand, you regularly train your arms with a high volume, I think you're not going to benefit much from it. I'm posting because a lot of you were questioning this program in the article discussion section and in another thread about a similar program.
