Personally, I like Jackie Warner's DVD's. She has two DVD's out, you can check them out on Amazon.
The one with the purple on the cover is the first one, the blue one is the newer one released end of last year or beginning of this year.
What I like about her DVD's: Each is divided into 3 sections (upper body, lower body, abs). You can either play all three, or only one or two. You can also determine the order. For example - I hate doing legs so I always do lower body first (to have it out of the way).
The weights that you use are entirely up to you. You can start with 2 or 3 lbs (I would go with 5 - JMHO) and increase as you improve. For each exercise, there is one person of the team doing the modified version (one is doing the lighter version and another person is doing a more intense version).
I like Jackie's style very much. She does not waste time chatting (I cannot stand that). Also, I liked that her DVD's don't have any wasted time (or at least it's cut down to the minimum) - you know, the stuff you have to watch but are not interested in every time you play the DVD.
I would recommend the first DVD (purple) over the blue as the individual sections are 20 minutes each. On the blue one, they are 15 minutes each and a bit more advanced. Or, get both and alternate.
