BACK FLY
Preparation
Attach handles to both sides of a resistance band. Run the band around your body and grab the band by the handles. Raise your hands forward and upward until they are horizontal to your shoulder. Keep your feet hip width apart.
Execution
Move your arms to the sides and back. Keep your arms extended and parallel to the floor. Continue the movement until the arms are extended to your sides. After a pause, return to the original position and repeat.
