A common modification made in paschimottanansana, is to sit on the edge of a blanket to elevate the hips and create a slight anterior tilt to assist the forward bend and prevent rounding in the lower back – the cue I have often heard and used is to “hinge from the hips”. I have understood this to be because in our natural structure the pelvis does tilt forward slightly. In this lecture, the instruction is to keep the tops of the hips back and bend from the naval which seems to me would result in rounding of the lower back. Perhaps I’ve got it all wrong.
Could someone please clarify and is it wrong to suggest sitting on something to elevate the hips and keep a slight forward tilt in the hips?
