So I'm about ready to make a run for the next level.
I have a kyphotic back and the part of the cat cow where you curl your spine around a ball has always been problematic for me. I'm doing this cold and you'll see the first rep is pretty inflexible, which is pretty much how I was when I started GST, but you'll see more flexibility in the last rep. I'm always open to anyone with some tips or links on fixing this. My progress has been slooooooow, even with physio and GST.
