Ribcage

During the arm reach, the ribcage should drop back into the chair rather than flare upward. Reaching the opposite arm overhead helps open the opposite-side ribcage and intercostals. The back of the ribcage should remain connected to the chair near the T8-T9 region during the reach. The reach is intended to occur while maintaining contact between the back of the ribcage and the chair. The forward reach should be performed without the ribcage kicking upward. The activity is designed to expand the opposite-side ribcage and intercostal muscles. The drill targets the ribcage and intercostals on the side opposite the elevated foot.
