1、Forearm Fulcrums develop an early vertical forearm (EVF) position and increase stroke efficiency by connecting the forearm and hand into a single surface. 2、Promotes stroke refinement through muscle memory of proper hand, wrist and forearm position. 3、Improves efficiency by maintaining a strong, uninterrupted pull from the beginning of the stroke to the end. 4、Calls for a high catch by lifting the elbow, ideal for open water and triathlon training. 5、Great for all four swim strokes: butterfly, backstroke, breaststroke and freestyle. Develop Early Vertical Forearm (EVF) and increase stroke efficiency with the Forearm Fulcrum Paddles. An EVF position utilizes the entire forearm during the pull, from the fingertips to the elbow. When using the Forearm Fulcrum for stroke refinement, the paddles promote muscle memory of the proper hand, wrist and forearm position. Gain efficiency and maintain a strong, uninterrupted pull from the very beginning to the end of the stroke. The Forearm Fulcrum is beneficial for all four competitive strokes. Specification: Material: TPE / TPP Function: Correct the swimming stroke, make the stroke more standard, and the stroke efficiency is higher Application: swimming and other wading sports Applicable swimming styles: freestyle, backstroke, breaststroke, butterfly stroke 1 pair Elbow Straightene
