The Wo-man with the Plan

Given that the winter is frigidly cold and has been preventing me from proper training, I've decided to take action. Indoor action. I've added about ten fitness DVD's to my Netflix queue focusing on those that play instantly. One is even a two-volume set for New York City Ballet exercises. I am sure that these workout DVD’s will help fulfill my childhood desire to be a ballerina (if only they had fitness DVD's on how to be a gymnast and astronaut). With a plan like this, how can I not be in tip-top shape for the October marathon?
