HOW: Begin by sitting sideways in a chair. Try to have the knees as high or higher than the hips. Wedge the thigh closest to the backrest into the support. Begin to turn towards the backrest as far as you can. Use your upper body to pull on the backrest for added overpressure and further motion. Exhale as you deepen the stretch.
Repeat for duration or reps.
FEEL: You should feel a stretch in your mid back.
COMPENSATION: Avoid straining in the neck. Avoid holding your breath.
