Here is a very simple exercise to practice stabilising your torso to elicit greater freedom on the hips.
When we learn to stabilise the torso in optimal alignment (neutral spine) we give ourselves the opportunity to disassociate the femur from the pelvis. In doing so we can truly exploit glide in that area in a very gentle way. Juicing up the hip joint, without all of that aggressive “stretching” usually associated with hip opening. Remember the core muscles are volumus and respond to exhalation. We are not scooping, or pulling navel to spine. We are simply trying to communicate with the centre of the torso- wide from pelvis to neck. Add it to your daily practice at the warm up stage. Enjoy.
