Hi-welcome to the forum..
I was wondering do you have arthritis or chronic pain?
I do have Osteoarhtirits amongst alot of other autoimmune diseases..The only part I can agree with is that exercising lightly keeps me moving..If I did strenuous exercise I would not be able to move due to the inflammation it would cause in my muscles..
I do have chronic pain also and have for years-unfortuantely exercie has not stopped the pain but it keeps me moving-I would freeze up if I didn't do some exercise..
Exercie would be a true healer (if) it worked that way for so many of us..I wish it did-I really do..For anyone it takes the pain away for I say go for it and congratulations..FOr me I can't hardly write anymore-certainly not that legiable so I type..Typing is getting to where it hurts more after the last fall I had..But, I continue to keep fingers moving..
