This is Yoga Synergy’s trademark exercise: Spinal Movement, as taught by Simon Borg-Olivier in 2018. Spinal movement is the foundation for Yoga Synergy style of practice. It consists of seven movements that mobilize the spine in seven directions: lengthening, flexing, extending, lateral extending right and left sides, axial rotation to the right and left sides.
It is interesting to point out that these movements rarely happen in our daily life because most of our “spinal movement” is combined with shoulders or(and) hips through associated movement, or a combined spinal movement involving more than one direction at a time (ie. flexion with lateral extension, axial rotation with extension etc). More information about the benefit of spinal movement can be found in my earlier post: “Why Spinal Movement?” https://artanvaya.com/2019/02/15/why-spinal-movements/
