@Peaceful A female friend of mine has a rather slim figure and on the other hand has quite a tough job in retail. She once said she always has aching muscles the first day of work after 2 weeks long holidays, in which she sometimes receives professional massages.
@Peaceful I don't know actually. All she said was that "sometimes it's just necessary". Yesterday she also told me that she does expressive dancing, I really don't know how that looks like.
@scooogy muscles have a memory to them innately. So massaging them wouldn't destroy them. Perhaps it would create healing pathways that could make a person feel like it in the moment. 馃
