First off, we are very pleased to hear that you are enjoying the community! Thank you for your kind words!
To answer your question, we post a new Master Trainer Audio Podcast once a month (a new one, "Simplicity" by Master Trainer Clare Dunphy, was just posted. Link to it here: http://peakpilates.com/community/files/folders/instructor_resources/entry619.aspx).
As for the Weekly Exercise Podcasts, a brand-new download is added to the series every Monday.
Please let us know should you have any questions or comments.
Enjoy!
