Crankin - it sounds like you can get away with less rest than I can. I DO try to do mobility work on rest days, and am trying to get into the habit of going for a walk on the second half of my lunch break. I don't consider it as exercise, but it gets me out from behind the desk and gives my hip flexors a chance to stretch. Unsure if I would still have this problem if I had been able to continue to ride as I liked, but that is water under a bridge that can't return.
