This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.

Yeah, I suspect it only really makes a difference if you're dealing with another issue or stressor on top of the statins. I've seen studies indicating that yes it doesn't change much in day to day life but that it increases the cardiovascular benefits of aerobic exercise in the population on statins, and anecdotally (DANGER! DANGER!) it made a sudden large difference in energy level and strength for a family member knocked for a loop by chemotherapy who had resumed their statins after completing treatment.
