This is what I've read and based on my personal experience I believe it.
I hope my explanation makes sense.
That sounds reasonable.
I'm always a little suspicious of these products - I don't see how they are going to change your 1 rep max or anything, but I guess the mental aspect might come into play in terms of effort level.
I wonder if the CNS can be stimulated by other external factors (loud metal music, the presence of a hot chick nearby in the gym etc) enough to give a training response.
