Yes, your body is already doing it automatically or you would be flying off into the weeds and bramble bushes.
Completely relax both hands so the bike is using physics to go in a straight line, then gently push straight forward on the bars with one hand or the other- you are going to gently turn in that direction.
Than forget you ever heard this.
I think they drill this into peoples heads so much that they start to have to think about it, and once a human has to think about something they will screw it up. Than they will be in the brambles, happens all the time on the open harley rides. They get people going uncomfortably fast trying to keep up, next thing someone goes wide in a corner.
I would say if you have ever taken a corner at more than 20 MPH you have already done this without thinking about it at all.
