Going to an Ashtanga Yoga class can be pretty intimidating. There are tons of poses, it moves pretty fast, and everyone seems to know what they're doing. As if that wasn't hard enough, your instructor might be calling the poses by their Sanskrit names.
Don't get stressed out. Yoga is supposed to be relaxing, remember? Before going to a class it'll help to know the poses ahead of time. So doing a little research is a good thing - there are books to help you out. Or you can hang a poster on your bedroom wall and study the poses whenever you're bored. Like to practice at home? Then pop this DVD in the machine and follow along.
Fit's Tip: When I was first learning Ashtanga, I brought a waterproof study guide to take to class with me. It'll put your mind at ease and help you learn the order so you don't feel lost.
