I've been practicing for 12 years and have taught on and off as time allows. I'd strongly urge you to find a studio and a teacher as it is much easier (and safer) to learn with an instructor observing. There are many styles of yoga and I urge you to shop around and see what you like. I checked the yoga journal teacher directory for Des Moines and they didn't have anyone listed so I can't help you there but if you have any specific questions I'll help as I can.
