The work of activation is a lot like sex.
If you force it, it is rape, not sex.
So when the going gets really tough, when you find yourself stupid, let up... allow yourself to breathe.
It needs to be voluntary...
I am watching a bunch of you forcing, as if you had to... whatever.
If you are ready, and muscle test said yes, then allowing the muscles relax, allowing yourself to feel safe, and try again later is the way to go.
How much later? An hour?
