This is a commonly used Pilates term, meaning a position where the knees are bent so that the thighs are perpendicular to the floor and the shins are parallel to the floor. A must-have top ten Pilates move!
To put it simply – the bones in your behind! These are the protruding bones that you feel underneath you when sitting up straight; they are part of the pelvic girdle and medically known as the Ischial Tuberosity (that’s bum bones to you and me!)
When our lovely personal trainers say, “DEEPEN THE ABS; BELLY BUTTON TO SPINE”, over our reformer beds, this is what we mean! The scooping of the abs is desired to lengthen and deepen the abs in towards the spine, to create a feeling of hollowness.
