Hello Liz Davidson,
Exercise is any activity that is done to train the body and mind.
It can also be described as anything that is done while awake; because, there are many who can only breathe with assistance and still manage to exert themselves.
You may also think about how reading and thinking slow the recovery process after a concussion.
Lastly, where there’s a will, there’s a way. How is that for mind-body connection?
