Jamie Eason's LiveFit Trainer - Phase This is a 12 week program, print the workouts and take them to the gym. They have videos for all the moves so you can learn them before you go. I am on week 8 and have never felt better! I HIGHLY recommend!
Bodyrock TV just introduced Bodyrock lite for those of us who are just starting out on this whole regular exercise thing. Works on building your core strength which is really the key to upping your workout intensity.
