Pocket yoga was definately worth the download! I have been frequenting both Sun Salutations as they are great for a quick yoga fix. The calming music is a great touch to the program, and really helps you to relax. I have yet to try the longer verions (ie. Desert, Mountain, etc.), but will do so promptly. The narration of this program is good, but is not great for absolute beginners. I recommend learning proper breathing techniques and correct posture in order to get the greatest benefit out of this program. Still, it is a very good program for improving flexability, even if youre not as interested in becomning a yogi and doing it more for the benefits! For me, the feature that would put this over the top would be if the pictures of the poses throughout the program were animated, thus flowing more smoothly. I find the transition between images to be a bit abrupt, but the narration makes up for it. I definately recommend downloading this app for beginners and advanced yogis alike!
