I wanted to share a few of my blog/podcast resources:
Jennifer Gianni's blog has amazing, anatomically correct information for working different areas of your body.
Pilates on Fifth is a video podcast produced at a great studio just outside of Times Square in New York City. This is a great, no cost way to learn exercises when you can't make it into a studio.
Pilates Digest & Pilates-Pro are both great online magazines dealing with every aspect of Pilates and studio ownership. There are also discussion forums on each site.
