Welcome to Nose-Campus: Polyvagal Theorie explained by its inventor:

www.fitnessblender.com

Just a tiny bit of advice regarding fitnessblender. It is a very reasonable site for wide range of fitness classes with a strong focus on body functionality. There is plenty of free stuff to choose from. You may need a exercise mat or if you like weights, but you can also google for "no equipement" and "fitnessblender". I recommend to open a free account. It comes with the advantage of a search engine for which kind, which body part, how long and which level you want to exercise. Besides that it allows you to track your exercises via a calendar, what can be a great motivational factor. (www.fitnessblender.com)
