I am totally into Yoga right now and it is the best form of relaxing exercise there is out there. If you didn't know, Erin just got a Wii Fit for her birthday and Yoga is a very popular "game" to play on the fit so hopefully these poses will inspire her to flex her limbs and stretch herself out. The pose above is the very general meditation pose (that actually I've never sat in in an actual Yoga class, but it is still very popular). And below is my ALL time favorite... The Bow.
Lastly, what I just learned to do (and my boyfriend mastered before me) the headstand.. here's a little step-by-step how-to in case your feeling courageous.
