Here is a quick YouTube video from Vince DelMonte titled "Get Back In Shape Plan", which is a great workout for anyone getting back into the gym or starting for the first time.
Vince has dozens of excellent videos on his YouTube channel for all levels of fitness, and also specialises in weight training and nautral bodybuilding. Visit his page here: http://www.youtube.com/user/VinceDelMonte.
He is also the author of several fitness packs including some of the best instructional dvd's I have seen, which will allow you to learn the correct technique for all of the workouts. As a personal trainer, I have used many of his workouts with my own personal training clients.
