Major element of Breath Support = Abs (more specifically, the Transversus Abdominus)
It can be difficult to get a sense of where the Transversus is because it is the deepest ab muscle. Most crunches work the surface muscles, the Rectus Abdominus. Here is a tweak to move some of the work to the Transversus so that you can feel where it is and how it works. (This is the Core muscle that Pilates work is targeting so much of the time.)
