Sit comfortably in an upright position. Place a therapy band behind your shoulder blades and grasp one handle in each hand. Your hands are at chest level and your elbows are elevated to approximately 90 degrees. Press your hands forward, extending your elbows, so your arms become parallel to the floor. Be careful not to lock your elbows at the end of the motion. The therapy band provides resistance. You'll feel your chest muscles contracting. Relax and return to the starting position.
