Twelve-hour chair mobility

Twelve-hour days in a fixed chair cost you posture, then focus, then money. These eight movements take four minutes and can be done seated between hands: neck rotations, thoracic opener, seated hip hinge, ankle circles, wrist flexion, scapular squeeze, glute activation, and a long diaphragm stretch. Run one set every two levels. It is unglamorous and it is the single cheapest edge in this library.
