This is a fun book--nothing deep but just a fun book to have by your bedside to grab when you need to un-kink. This is a perfect birthday gift for a friend.
If you're like me, you aren't sure when you became old enough to wake up a little stiff and sore and are wondering if this is the age you should look into expensive mattresses, pillows, or therapy? And you're not THAT old? Or, you could stop wondering this and invest less than $12 and a few minutes each morning and evening following these simple yoga poses. I can't tell you enough how much better I feel after about a week of this. The book is very attractively bound, easy to follow, and well worth it. I'm out of shape and it works - this is a great way to get active each day. I actually look forward to waking up and that has never, never been true. Try it!
