Many well-intentioned exercisers extend their elbow when trying to strengthen the rotator cuff. This is WRONG! Elbow extension keeps the shoulder from rotating and, as a result, renders the exercise USELESS. This is where the CUFF BOARD saves the day - or the shoulder! Because your forearm rests on the board, it PREVENTS the elbow from extending, and KEEPS the shoulder rotating. By allowing the shoulder to better rotate, the CUFF BOARD helps effectively BUILD strength.
