Here, Kipling Solid MMP LA, of Solid Bodies in Highland Park, Illinois shows one of her "Roller on the Low Chair" exercises.

In this Eye Test
the question is
which is the better posture.

The photos were taken in the order presented. Left to right or top to bottom. I like the first one. In asking for more height of the legs, in the second shot the legs are higher but Kipling loses that connection of head on her shoulders.
