I seriously hate this progression. I know that when I retract my shoulders tend to elevate for some reason. Other than that I feel like I'm getting good enough ROM, no? I also feel pretty certain that the mobility is pretty much mastered. I know I can go a little bit deeper on the im, but seeing as how I've not yet mastered the strength element, I've got time to open the hips the remaining centimeters until they're to the floor. Let me know others' thoughts.
