I constantly shifted around so that the strain was never in the same place. Otherwise it would end up killing my tailbone in no time. I would raise and lower my chair. Shift my ass from close to the edge, to right on the edge, to hanging off the edge. My feet would be on the floor, on the feet of the chair, off the floor with my knees jammed into the desk, or all the way up on my desk.
ok so u tend to vary very much your position. thanks for the answer. I’ll have to do that to as my tailbone is in pain after the sets.
