I've linked to blog into shape before, but this post really does lay out the basics of cardio and weight training - clearly and concisely.  The description covers the basics that I've read about in every exercise plan I have looked at.

Missing would be diet and stretching, but the exercise portion is covered, in about 10 short paragraphs.  You can buy books that go on about the same basic program, that go on for 10 chapters!

It's worth a look. 

Saw this.  Thought it was cute!
