The document provides guidance on functional training for endurance athletes. It discusses the importance of functional training for injury prevention, biomechanics, and performance. The document outlines sample routines for proprioception, range of motion, tissue management, core development, and strength training. It emphasizes proper progression of training frequency, intensity, and time to avoid injury. The routines shown are meant to be integrated into a full training program over multiple phases to develop an athlete's strength, power, stability, and range of motion.
