Engineered for training on all levels, the Catalyst Contour Training Paddles from TYR Sport, Inc., follow the form of an athlete's palm to provide a natural swim experience when training. Designed to build strength and improve technique, the curved surface paddles guide the arm through the stroke to accentuate proper form and maximize training. A proper stroke with the Catalyst Contour Training Paddle guides the arm straight back through the water with minimal resistance, building muscle memory for proper alignment. In contrast, an improper stroke will be exaggerated and the arm will be thrown off course. Showcasing Polypropylene construction and multiple lacing options, the Catalyst Contour Training Paddles offer the perfect balance between impact resistance, flexibility, and fit.
