Pectoral Mobility

The reach should gradually increase during the long exhale to enhance pec opening. Sliding the opposite arm forward helps open the chest on that side. Positioning one arm reaching down and inward while the opposite arm reaches across the body addresses the pecs on both sides. The reaching portion uses the arms forward and outward during the exhale. Overhead arm placement is part of the drill's intended mobility and activation effect. Chest opening is one component of the supported movement pattern used in the activity. The arms are placed slightly overhead rather than fully relaxed. The arm opposite the wall-pushing leg is used for the forward reach. The drill is designed to open the chest on both sides. The drill is intended to open the chest.
