If you don't know what you're doing you're wasting your time. Go to a gym to learn form. Pick up a book or a video. Something like that. Otherwise you're going to wear yourself out with nothing much to show for it. Once you can do the exercises correctly knock yourself out.
God, so atrocious in the Old Testament, so attractive in the New--the Jekyl and Hyde of sacred romance.
-Mark Twain
If people are good only because they fear punishment and hope for reward, then we are a sorry lot indeed.
-Albert Einstein
