Even in the age of the Internet, don't underestimate the value of looking at photos and reading descriptions in a book. For one thing, you can keep the book open on the floor while honing your asanas at home. Browse your bookstore or book website such as amazon.com and search for “yoga” and whatever other terms interest you, such as “bikram yoga DVDs,” “ashtanga yoga books,” “yoga for kids,” or any yoga type you want.
