On rest and recovery days it is important to avoid doing the worst thing you can do for your body... nothing. Examples of rest and recovery activities are walking, static stretch exercises (after a warm up and loosening up period), dynamic stretching, swimming, water running, and riding a bike.
This includes walking (after running activities) and the performance of the RD at the end of all PRT sessions. Recovery gradually and safely tapers off activities to bring the body back to its pre-exercise state. The element of recovery carries over until the next exercise session is performed. Restoring adequate hydration and energy balance through proper nutrition and ensuring adequate sleep allows the body to refuel and rest. This results in a positive adaptation to the stress of training, improves Soldier resiliency, and optimizes gains in strength, endurance, and mobility while controlling injuries.
