Appreciate the responses.
Good distinction; there is a global extension drill using a keg in BASL. I don’t believe there is any mention of global flexion…
Do the concepts midline stabilization and organization (body mechanics) Kelly teaches apply to yoga? For instance, in the Yoga position cobra (http://www.dofitnessnow.com/wp-content/uploads/2013/01/Cobra-style-yoga.jpg), should one squeeze the glutes or leave them relaxed? Would you classify this position as a local extension? Are local extensions good?
What is a “movement practice”? I’d imagine that means performing some permutation of the Category 1, 2, and 3 movements outlined in BASL, on a regular basis?
