Reflection about exercise for today 7/1/15

I realize that I was and still am right.  Exercise does a body good.  I have been lazy and tired to do a blog entry yesterday.  I have been extremely tired last night.  Using a computer was the last thing on my mind. Tonight I plan to do P90X.  I know that it is not for beginners but it is well worth it.  I am not sure how much exercise I should do.  Should I exercise daily?  Should I exercise per week?  I am tired of being just a beginner.  Lately I have come to realize that exercise has been of great help for me.  I no longer see it as a chore.
