When speaking of muscle mechanics, does not "relax" mean exactly that -- go limp?

I understand that that's not generally what people mean when they tell you to "relax", but then you ask "how" and they delve into a discussion of mechanics, and then they run into the problem that this is exactly what "relax" means. It's bad vocabulary to use "relax" when you mean something much more complex, as per Jon's example.
