balance
During vigorous activity, the body increases its metabolic work and free-radical production may rise. Glutathione is one antioxidant the body naturally makes and part of the systems studied in relation to oxidative stress and physical activity. Hydration, rest, and balanced nutrition also contribute to a well-rounded training routine.
