This might be my favorite exercise using the Wingmaster. When I used to teach online Wingmaster classes, this exercise, in either Setting 2 or Setting 3, would be included in almost every class. The feeling of this exercise is one of the most satisfying of all the Wingmaster material.
There are 6 spinal ranges of motion. In our Activities of Daily Living, circumduction is the movement we most likely use the least. That doesn’t mean it has no value. This motion is excellent for the health of the intervertebral discs.
Our discs don’t have any direct blood flow. Movement pumps our discs through a process called imbibition. While all the spinal ranges of motion help with this, the rolling of the discs between the vertebrae in circumduction ensures the whole circumference of the disc gets some pressure and release. Circumduction is also the only spinal range of motion that has no end. It’s a circle. Circles have no end.
