Always maintain good posture and body alignment. Head should stay in a natural extension of the spine with chin parallel to the ground and eyes focused on the horizon. The chest is lifted with shoulders back and relaxed with arms swinging naturally at your sides. Rehydrate - Always replenish your body with fluids depleted by aerobic activity. Drink 8-10 ounces of water for every 20 minutes of activity.
Water is the preferred drink for exercise sessions lasting one hour or less.
For activities exceeding one hour, consider rehydrating sports drinks to replenish lost electrolytes. Clothing - Choose loose fitting garments that allow your body's heat to evaporate. Consider the new sport fibers that whisk away moisture, preventing chafing of the skin. Wear reflective clothing at night. Shoes - Select a lighter weight walking shoe.
