The training for Apollo continues with the Dogtra collar. The Collar uses an electronic muscle stimulator to reinforce a dogs good behavior. He is barking less when people come to the door and is sitting in his place. We still have the unmodified behavior of Shadow however.
I feel like I have the same thing going on with my back. I'm Ok if I sit in the chair. If I attempt to get up and bend it anyway I get negative feedback that pushes me back into the chair.
So I'm OK until get up from the chair and it's like someone has a large remote control that gives me pain in my back if attempt to bend it.
