I just started getting interested in Yoga. I didnt really know where to start. I took a normal class and felt a little intimidated cause everything was moving way to fast. My friend recommended talking a beginner series so when I went to a regular class I wouldnt feel so out of place. I live in NYC and searched craigslist and found a bunch. I settled for a place at West 14th Street called Practice Yoga. Anyway it was a great idea cause it was four weeks and they taught me all the basics. I started going to the normal classes now and its great. Anyway I just thought I would pass this info along in case there are you beginners out there like me. I bet you could find them in a lot of cities if you dont live in NY. It is a great thing cause sometimes the other Level 1 classes can be to advanced for those of us who dont know much other than downward dog. lol.
Best Luck to Everyone!

Taking one or two private lessons also helps, so the instructor can give you his or her full attention.
