(Sorry, all! I have been side-tracked with my Ignite Your Life program the last few weeks and haven't posted much. I have a few ideas I still want to post before moving on to this month's pose.)
I spoke about grounding points in a previous pose. Here is great photo of really grounded hands. This student is pressing so firmly through the palms. When the palms are pressed firmly, you are able to lift up and out of them more easily so you can open the chest more fully.
You can see MuseKaren here getting a huge lift in her chest with her shoulders drawing firmly down. I like to have students practice in this position (I call it "The Sitting Dog" :-) ) because there is no strength needed and they can get the feel of what I want them to do without needing to struggle.
