The purpose of pre-workout nutrition is to fuel the body for optimal performance during exercise, typically consisting of easily digestible carbohydrates and some form of protein. This combination can enhance endurance and prevent muscle breakdown. Post-workout nutrition focuses on recovery, emphasizing the replenishment of glycogen stores and providing protein for muscle repair and growth. Consuming the right nutrients after exercise can significantly aid in reducing muscle soreness and fatigue, thus promoting quicker return to training and improved overall fitness levels.
