My observation is I need to keep my feet away from the wall quite a bit (Wall exercises), my lower back is definitely stiff but what I also find is that that in Pilates stance, my glutes are very much engaged so when they are squeezed my glutes and bottom is quite big and feels like the actual flesh keeping me away from the wall as they are sticking out, Hope it makes sense. I am naturally blessed with a big, juicy bottom which is also muscular from athletic training. #so is it possible that because of that I can never reach the wall? I mean I have lots to work on but want to check.
