Nutrition before and after cardio can help support energy, performance, and recovery. A pre-workout meal or snack can provide fuel for your session, particularly for longer or more demanding workouts. Carbohydrates are an important source of energy for many forms of cardio. After training, a balanced meal containing protein and carbohydrates can support recovery and replenish energy stores. Hydration is also important before, during, and after exercise. Your nutrition needs can vary depending on workout intensity, duration, and individual goals.
