Too Much?

It seems I won't have a chance to work out Thursday, so I'm making up for it today. Or am I? Working out the same muscle groups 3 days in a row without a day off may work, or it may over-stress those muscles and joints giving a diminished return, with increased risk of injury. I guess we'll see.
