I tried the series hoping it would be fun for a beginner. I found it too rigorous "flowing" from one position to the next a little bit too often to ensure proper posturing for me. Thanks, but no thanks. I want to feel centered and revitalized after a yoga session - not Jane Fonda exhausted. I'm sure some instructor somwhere loves it. I'm an average size 16 and it just moved too fast for me, after one year of yoga experience.
