PRODUCT DESCRIPTION The Bolster paddles develop an early vertical forearm (EVF) position and increase stroke efficiency. An EVF position utilizes the entire forearm during the pull, from fingertips to elbow. The wide paddle design provides added resistance to build upper body strength. Specific stroke refinement is promoted through muscle memory of proper hand, wrist and forearm position. The Bolster paddles are a versatile tool for all four swim strokes.
