Classic! I couldn’t describe the work better myself. Below are two videos of the woman who created ‘Rolfing’ or Structural Integration, Ida P. Rolf. Back in her day there was a lot more use of the metaphor of stacked blocks to describe the body and it’s alignment, though her understanding was incredibly nuanced. I remember hearing Joseph Heller (created Hellerwork) tell a story about how they were at a restaurant and when a waiter walked in wearing a suit, she could pick out that his quadratus lumborum was short. Amazing.
