I was practicing my set-up in the mirror, making sure my right forearm is on plane. I noticed my back is not in a straight line from the base of the neck to the tail bone, in other words I am in a slightly slouched position. I have the same amount of slouch when standing (bad habit, I know). When I try to straighten my back, it is both ridged and slightly painfull. Is this something I should look to change or is it ok since it is my natural standing position. I am not talking hunchback of notre dome here, just slightly slouched
