Short box - thoracic mobility
I wanted to show the hyperextension done in the reformer short box and the way I believe it should be done to be "good for the body" in Joe Pilates words. First both Bruno (the boy) and Zorica (the girl) hyperextend by letting themselves falling backwards arching mainly in their lombar spine. Actually this is what I've seen mostly people doing in this particular exercise. In the second attempt both practitioners kind of stop when they reach horizontal with their spine and from their they arch mainly through their thoracic spine. I'm helping Zorica by placing my hand/arm approximately in the middle of her thoracic spine and Bruno is using his elbows against the edge of the box to help support and direct his arch correctly. Of course, the aim is to do the bridging with no help from an external support. According to Michael Boyle's "joint by joint approach", the thoracic spine should be trained, in most people, to increase mobility whereas the lumbar spi...
