I've used it in the past and enjoyed it. The only reason I stopped is that I generally prefer gym workouts. The strength routine is really great. I think you'll enjoy it.
If you go down to the fitness video section (two below this) there are a lot of people who use Turbo Jam including a lot of preexisting threads about it. I've actually thought about buying it too, but I'm not very coordinated either. It does seem like fun though!
Does Anyone Use Turbo Jam?
