So I recently bought this DVD because I saw Sara Ivanhoe on a Netflix Watch Instant yoga session and really liked her style. I've been doing this routine every morning because its only 20 minutes- and I can already see a difference in my posture and core. She's fun, calming and with a price of $6.99, its totally worth it. I just light some incense and candles and I'm on my! The only reason I didn't give it 5 Stars was because there's 2 work outs that require a ball or strap or something which I don't own. But hey, if you've got these tools, even better! And if you don't, just skip them and do a different routine!
