My best present this year came from one of my yoga teachers--my very own yoga bolster for my home practice. (If you are picturing someone doing something crazy difficult, don't!) Here's how I use it, except I add a yoga block instead of the towel suggested in the text) under my head. Without it, my neck is bent back and my chin juts into the air. This is a great shoulder opener. Sometimes I also bend my knees, put the soles of my feet together, and put blocks under my knees for support. That's a hip opener. Restorative yoga is a gentle, comfortable way to increase flexibility.
