Our model today was Trace Devai. Instead of a demonstration I showed you the video I posted online last week. I will post it below this week as well.
There are many ways to simplify the human form in order to see gesture and the interaction of various anatomy. The interaction between torso and hips is usually the core of a poses movement. If you can get that relationship right you will usually capture the essential gesture of the pose. With that in mind I think the approach outlined in the video is worth considering and practicing.
Take a moment to watch the video and I would suggest practicing the exercise with some of the reference photo's available at their website: www.proko.com
