Instructions
Seat yourself on a solid chair, with your back straight and unsupported. Keep your feet firmly planted on the ground at a comfortable width.
Place your hands on your upper chest, crossed at the wrists.
When ready, turn your body to one side while keeping your glutes in full contact with the chair, maintain an upright posture.
Twist your body until you feel a light stretch in your lower back, hold, and then return to the starting position.
